Villain Overview
After being sealed away within this box, I have no clue about what has happened outside and I don't know how much time has passed. The hatred in my heart only keeps growing. After thousands years, I was imprisoned in darkness. But then one day, that priestess opened the box. Yes, in that priestess' heart I found a similar resentment. Hatred. Anger. A perfect tool for my revenge upon humankind.
~ Herrscher of the Erosion in Sakura Samsara.
Evil? I? You hurt me like that. What's so wrong killing humans? Why it's so bad making them suffer? Why it's so bad to crush their children like bugs? Why it's so wrong to cut their head off while they are alive? Why it's so wrong to make them suffer right in front of their children and lovers? They are toys! Toys! Get it right.
~ Herrscher of the Erosion showing her psychopathy.
Finally! The light has been defeated! Once the scar appears in your heart, this will be the moment that you and I become one! Finally... this is the moment I've been waiting for for 500 years! I love you, Sakura. Now, you will be trapped inside me... and live a painful eternal nightmare.
~ Herrscher of the Erosion rising to power.
You should be thanking for making the foolish delusions of the villagers become reality! To be devoured by a God you love and believe in, isn't that a blessing?! Don't you think it's hilarious when both demon bear that is feared and the fox god that is loved are basically the same thing?!
~ Herrcher of the Erosion to Kallen.

Herrscher of the Erosion, also known as 12th Herrscher, HellmaruRuler of the Erosion12th Ruler or self-called as Yakujin or God of Disaster, is the overarching antagonist of the popular iOS/Android mobile game Guns Girl Z (also known as Houkai Gakuen 2) and appears as a major antagonist in its sequel Honkai Impact 3. Herrscher of the Erosion is introduced as the main antagonist of the School Dayz manhua, the overarching antagonist of Honkai Impact 3rd - Purple Kite's Tales, the central antagonist of Honkai Impact 3rd - The Secret of God Keys, the main antagonist of Honkai Impact 3rd - Gratitude Arc and the main antagonist of Honkai Impact 3rd - Sakura Samsara story arc. Due to her machinations in the Old World and starting the Second Apocalypse, she is considered to be one of the most important antagonists of the franchise alongside her successor Herrscher of the Void.

The 12th Herrscher was a Houkai self-aware lethal virus which infected everybody and turned all life forms into zombies and was capable of controlling machines, launching nuclear missiles and destroyed a part of the old world. In an attempt to destroy mankind to create a world where she could rule everything, she planned to destroy all life existent but Professor Mei sealed her inside of the Purple Box before she could  destroy the rest of human civilization. 49,000 years later after God Kiana reseted the world, she was still sealed inside of the Purple Box until it fell into Schicksal's hand, causing the Black Death in Europe during the Medieval Era of the New World, killing 1/3 of the population of the world. After witnessing the inhumane experimentation of Schicksal using Crystal Disillusionment, Kallen stole the Purple Box and ran away to Yae Village in Japan after being atally wounded by Shicksal's hunters. Yae Sakura later unwittingly opened the box, releasing the Herrscher of the Erosion and all her stored hate all over the past time and possessed Sakura, turning her into a large fox beast that was later defeated and sealed by Kallen.

In another attempt to escape, Herrscher of the Erosion managed to drag Theresa Apocalypse to her Stigmata World (a weapon that used to belong to her predecessor Kallen Apocalypse) and took control of her body for a short period of time until the interference of the Shicksal Valkyries. She was sealed by Theresa again but later returned in during the events of Sakura Samsara in another attempt to break free but was permanetly sealed inside of a katana inside of the Stigmata World with the help of her previous vessel, Higyokumaru.

As Higyokumaru (the only vessel she got to be dubbed as) she is voiced by Shiori Izawa in the Japanese version, whom also voiced Mary Hughes in Fairy Tail and Matsuri Mizusawa in Citrus.

Official Description

So many suffered because of this demon. Seal that beast away and let her to rot in eternal darkness.
~ A scientist of Fire Moth about Herrscher of the Erosion.

The 12th Herrscher was a Houkai creature that had the ability to project her own consciousness onto any object and control it freely. In reality, this Herrscher was actually a self-aware lethal virus which was coloured black, which infected everybody and turned them into zombies. Not only that, but she was also able to control machines, launching nuclear missiles and destroyed a part of the old world. Professor Mei had to seal her into the purple box before she could destroy the rest of human civilization during the crisis of God Kiana's awakening.


Herrscher of the Erosion, the 12th Herrscher, burning in hatred for all life.

50,000 years later, the purple box later fell into Schicksal's hand and was experimented but it resulted in the start of the Black Death on Europe and wiped out 1/3 of all world's population. Eleanor Schariac injected a fragment of this Herrscher onto herself, becoming a large spider beast and later got defeated by Kallen and Otto. After witnessing the inhumane experimentation of Schicksal using the Crystal Disillusionment, Kallen stole the purple box and ran away to Yae Village but later got fatally wounded. Yae Sakura later unwittingly opened the box, releasing Hellmaru and all her stored hatred all over the past time and possessed Sakura, turning her into a large fox beast that was later defeated and sealed by Kallen.

Hellmaru serves as the boss of the 3rd storyline of Sakura Samsara mode. A Honkai Beast in the shape of a Kitsune, it was the beast that corrupted Sakura as she held Kallen's Honkai box, causing her to turn into a pseudo-Herrscher. The 3rd storyline event causes it to come out of Sakura's body to become fightable. Her previous vessel, Higyokumaru, currently resides in the Stimgata dimension after the events of the Sakura Samsara.

Valkyrie Armor Story 1

In the Stigmata Dimension, Yae Sakura's appearance is affected by Higokumaru's powers. The miko attire was replaced in favor of durable armor, and her long hair was bundled up for battle. Compared to an average miko, maybe she is closer to a [samurai] now.
~ Valkyrie Armor Story 1.

Valkyrie Armor Story 2

Yae Sakura, who had never left the village, was never properly trained in the arts of handling a sword. Her mastery of the blade comes soley from her own study and practice. However, in this stance Yae Sakura can easily wield her katana and wakizashi and cut down her enemies with precision. This may also be the result of Higokumaru's powers, as she can only achieve such might in the Stigmata Dimension.
~ Valkyrie Armor Story 2.

Valkyrie Armor Story 3

In the end, Yae Sakura chose to stay in the Stigmata Dimension forever. After 500 years, those whom she loved as well as those whom she hated have all passed away. This fantasyland of hers is the only place she is truly familiar with in this strange world.

his is the battlesuit used by the Far East Vixen, the final boss of the game "Kallen Fantasy VII". The Fixen is the queen bee of St. Freya High and reigns supreme from the chapel tower, waiting for anyone foolish enough to challenge her...
~ Valkyrie Armor Story 1.

Valkyrie Armor Story 2

Be warned. The Vixen has 2 attack modes: close quarter sword slashes and cold magic spells. She is also extremely agile. Targeting her with ranged weaponry is a nightmare. Although her battlesuit looks high tech, it only provides minimum protection. Counter-attack her when she exposes her weakness between her onslaughts to deal maximum damage.
~ Valkyrie Armor Story 2.

Valkyrie Armor Story 3

Although Memento is a battlesuit featured in another game title, it is surprisingly comprehensive and features design-for-manufacturability. It is also extremely similar to Ritual Imayoh, another battlesuit featured in-game. Perhaps "Kallen Fantasy VII" is not a simple game.

Stigma Memory Clip 1

Higokumaru had many names. She hated some of them, and couldn't remember others. When people asked about her name, she would feign hesitation and then give an innocent smile: "Higokumaru! That's what Aneki would call me!"
~ Stigma Memory Clip 1.

Stigma Memory Clip 2

She likes Yae Sakura... and gives an equal amount of love to fried tofu as well. In fact, she would stay up all night waiting outside the village snack shop to munch on the first batch of freshly fried tofu. This simply means she would sleep through the day.

Stigma Memory Clip 3

Higokumaru enjoys addressing any girl as "Aneki" (elder sis), no matter how old they may be. The word "Aneki" is super special to Higokumaru. It spans 50,000 years of lost time and allows her to reminisce about her times as a young girl.

Yae Sakura and the 12th Herrscher.

God? You call that thing God?! That thing is a Houkai! A pure monster!
~ Theresa Apocalypse about the "God" of Yae Village.

The sadistic, narcissistic, arrogant and vicious Herrscher of the Erosion was the 12th Herrscher of the Old World that came to existence during the crisis of God Kiana, the Last Herrscher of the Old World who would later become the Herrscher of the Void. Unlike other Herrschers, the 12th Herrscher was a peculiar entity who was revealed to be a sentient virus who could think and act like a normal person. She was born as a self-aware virus entity that sought to bring as much pain as possible and crossed the bounds of even the most heinous Houkais. Unlike other Herrschers that had their hatred focused on mankind only, the Herrscher of the Erosion was a cruel monster who sought to dominate everything, including other life forms, something that Houkai were not supposed to do as their mission was only to only cause the extinction of humankind.

The Herrscher of the Erosion was different from any known Herrscher in terms of sadism and preferred to inflict pain and despair upon her victims by using human methods. While Herrschers refused to have contact with the human world and chose to cause random destruction, the Herrscher of the Erosion liked to use humans to do her dirty work and played with their feelings to destroy people's bonds so they could reveal their true nature. The Herrscher of the Erosion makes herself unique due to how she represents the humanity on its dark side: someone hopelessly in love with cruelty, savagery and all the worst aspects of human nature with no qualms about witnessing or causing others' suffering. Another interesting fact about the Herrscher of the Erosion is that she was a manipulative genius who had people to do her bidding instead of using her god-like strength to get what she wanted, showing how much of a mastermind the 12th Herrscher was. She also possessed both uncommon charisma and a true gift for persuasive speech for a Herrscher who (mostly) sees everything in a manner of hate and genocide while the 12th Herrscher was cold, calculating and a genius in human's psychology.

The Herrscher of the Erosion has no compunction about dealing death to those who either stand in her way or those of whom she has grown tired of abusing mentally, either with her own hands or breaking their will to live to make them commit suicide. Using the hatred of her vessel, the 12th Herrscher used her energy to spread herself across the world and attempted to destroy the world in a nuclear war that wiped out most of the surface of the planet to set herself as a God for being "too perfect" for this world but failed when she was sealed inside of a Purple Box. More than 50,000 years later, she was freed by Shicksal's scientists that used the Purple Box to academic purposes. However, the results were catastrophic when the vicious Herrscher evolved and spread the bubonic plague across Europe, starting the Black Death.


The bloody sakura flower.

The Black Death, pandemic that ravaged Europe between 1470 and 147X, taking a proportionately greater toll of life than any other known epidemic or war up to that time. The plague created a number of religious, social and economic upheavals which had profound effects on the course of European history. The Black Death is estimated to have killed 30% to 60% of Europe's population. In total, the plague may have reduced the world population from an estimated 450 million to 350–375 million in the 14th century. Because of the Herrscher of the Erosion, the world changed completely and gave birth to extremists like Otto Apocalypse who was separated from his love interest Kallen Kaslana and set the events of the game in motion.

The thing that truly separates the Herrscher of the Erosion from the rest of the Herrschers and Houkai, however, is the fact that despite her diabolical intentions and actions she serves no God (unlike other Herrscher that serve the Houkai God) and does everything to set herself as the superior being of the world.

Secret of the God Keys comic revealing the past of the Herrscher of the Erosion and Yae Sakura.

Long ago when I was a child, I always thought that the greatest evil humankind could evoke in this world was done in the name of the greater good, for justice. For me there was not true evil even after seeing Houkai. But then, that Herrscher appeared and proved I was wrong. There is such evil that exists only for destruction. There is evil in this world which exists merely because of hatred and spite. A purely evil entity does exist.
~ Yae Sakura about the Herrscher of the Erosion.

The Herrscher of the Erosion was proclaimed God of Disaster and considered itself as the superior life-form of all living beings, hating everything that was not herself for being inferior and was a complete psychopathic narcissist who hated all human beings for self-proclaiming as the superior race of the planet. Despite her hatred for all life forms, she holds respect for other Herrschers for having the same mission that was given by "God", the only thing that the 12th Herrscher fear, for they were misanthropic figures like who could strike fear into the hearts of even the strongest Valkyries but she was not above looking down on them to set herself as "mankind's destroyer".

The Herrscher of the Erosion despises human values like justice and honor, which is why she hates how the New World's organizations founded to fight the Houkai, she especially hated civilized people as much as she hated people simply for being born humans, a race she considered fragile in a senses. She also dislikes religion to an absurd level. By her early actions, she is displayed as sadistic and cruel and even insane as she shows no importance who will win in a war as long her machinations inflict pain in her victims and show to be useful for her own purposes (if they are suitable vessels). She sees everyone and everything not as a living being, but as an object to be dominated and controlled—including her own vessel who gave herself to her so she could have her revenge on Fire Moth for hurting and killing her with no apparent reason. 


The 12th Herrscher forcing Yae Sakura to kill her sister once again.

She has little respect or regard for most others around her, and was even willing to turn animals, species that are not target of the Houkai, into monstruous beasts just to sent them to villages to spread chaos and destruction to make the villages worship her in order to have more children and infants sacrificed to grow more powerful. As a Herrscher, the Herrscher of the Erosion despises love, as she believes this emotion is the most disgusting feeling a living being can feel thanks to the affection people feel for each other. However, she does have an intense sadistic pleasure in breaking the relationship of two people in love with each other to a cruel level where she forces one of them to kill their loved one so the "killer" can live forever with depression and lose their sanity, becoming insane psychotic killers. In other cases, she let them live just so she can watch them commit suicide.

She is described as cold, haughty, and self-assured. She tends to capture the darker side of humanity and does her best to represent the greatest monster humans can be, often portraying herself as a pure and compltete monster to make people fall under her grasp. On the surface, when she is not being a Herrscher, she is a well-mannered, charismatic and compassionate young woman who passes the image of an innocent beautiful girl (in Yae Sakura's body). Pretending to be a human, she possesses a myriad of favorable traits and can easily overwhelm individuals with her seemingly flawless nature and can easily steal the identity of a person without doing putting much efforts in her actions. This makes it easy for her to make manipulate the citzens of Yae Village into doing various deeds for her, including killing babies of the town. With such skill in creating this facade of perfection and pureness, the 12th Herrscher can hide her true motives with ease. Within this perfect contrived exterior, however, the 12th Herrscher could study humankind's behavior and callously delivers destruction and suffering to those who happen to fall prey to her schemes without moving a finger, something that even her successor, Herrscher of the Void lacks as she prefers to do everything with her own hands rather than using her minions to do her dirty work (and avoids having contact with humans at best). The Herrscher of the Erosion also exhibits psychopathic tendencies despite self-proclaiming to be above humans. For example, most of her murders, have been premeditated and calculated.


Herrscher of the Erosion speaking with her vessel, with the latter amazingly tryin' to ignore the Herrscher's murders.

The Herrscher is also an entity shrouded in mystery. At times, she expresses her eccentric personality through her unique method of talking, and is amazingly both polite, calm and serious. She sometimes acts suggestive, likely as a means to creep others out, calling Theresa a "cute" and stroking Yae Sakura on her cheek like if she was trying to seduce her victims with an attractive casanova personality. She is rather bold and manipulative; she remains civil even during rituals where she watches Yase Sakura sacrificing children, patronizingly so, even in the face of hostility, and perhaps even to attract hostility from her enemies whom shows anger and disgust for how calm she can be even after committing an atrocity. When amused, her behavior is performative, and her expressions and movements are exaggerated.

Herrscher of the Erosion's ruthlessness grows until her true personality is revealed: she is not calm at all but wrathful, arrogant, evil, vicious, calculative, and twisted. Behaving unpredictably, the Herrscher remains casual and unfazed by the world around her when she sees her victory is ensure. She also has a dark sense of humor and an utter lack of empathy, finding cruel ways to taunt others using their emotions and worst memories (such as torture and death of friends, lovers and families) to break her enemies so she can expose them to physical torture.

Honkai impact 3 yae sakura 1

Herrscher of the Erosion's sadistic smile.

The Herrscher of the Erosion could be considered the only known Houka who was at least interest in mankind's dark saide and was hopelessly in love with cruelty, savagery, and all the worst aspects of human nature and had no qualms about witnessing other people's suffering and considered it to humans' true nature, which she embraced it and tried to wipe out pure people like who believe in peace and harmony to clean the world from those "disgusting" humans. 

She was also depicted as a very disturbing child-murder who had an obsession with killing innocent children and babies to eat their souls and use their vital essence as energy to grow more powerful than before. She is pleased to mentally abuse minors with the power she has over the village, and she does not care about the well-being or the people around her begging for her help for a better life. She does not regret anything cruel in what she does, seeing them as nothing more than another step to achieve her goals to get revenge on mankind and even after failing to destroy mankind once she did not give up and used Japanese villages to regain her lost power just so she could do the same thing over again. She also immensely enjoys the physical and psychological suffering of Valkyries, mercilessly oppressing them and making them fear her using their memories. All those who openly opposed her were subjected to extremely brutal abuse. 


Guns Girl Z - Old World

The world after Herrscher of the Erosion activated all nuclear missiles.

Herrscher of the Erosion, or also known as the 12th Herrscher, was a sentient self-aware virus that was fused with Houkai energy and gained free will to act and think by herself, which infected humans and animals and turned them into zombies.

The year that came to exist is unknown but it's expected she was born during the rampage of God Kiana, also known as the Last Herrscher of the Old World, who brought the end of mankind and destroyed the world. After Erosion gained freedom to think and act by herself, the disease immediately considered herself to be superior and saw all living beings as her playthings and deemed them to be unnecessary to her new world she is going to create

The virus then infected a little innocent girl known as Higokumaru and used her as a vessel to spread one of mankind's most deadly plagues that killed 90,000,000 people in just a few months. When the innocent girl was discovered to be the host of the disease, the now Herrscher of the Erosion used her energy to bring the army of Fire Moth straight at her, resulting in the innocent girl being tortured by scientists to discover a cure for the plague and then executed in cold-blood when they considered her to be too dangerous to be kept alive.

Once her vessel was was killed, the Herrscher merged her mind with Higokumaru's and manipulated her hatred to turn her into mankind's deadliest enemy. The virus quickly left Higokumaru's body and infected all civilians in the North Asia, turning half of China's population into zombies and hacked into America and Asia's nuclear bases, launching nuclear missiles of Fire Moth and destroying half of the world, killing billions more just to create her own Plague Kingdom. At some point, the Fire Moth captured her and had Professor Mei sealing the Herrscher inside of a Purple Box full of anti-Houkai energy, where Herrscher of the Erosion would be kept sealed for 49,500 years alongside her vessel Higokumaru

Honkai Impact 3 - New World

Medieval Era


The Black Death starts in Europe.

49,500 years later after God Kiana/Sirin reseted the world, the Herrscher of the Erosion continued locked inside of the Purple Box until one day in the year of 1490 D.C., the organization Shicksal (Entrophy) found the Purple Box and began to experiment on it in an attempt to use its majestic power in a weapon against the Houkai beasts that were wrecking havoc the continent of Europe, leaving entire villages destroyed.

However, the experiment resulted in the opening of the Purple Box, ensuring the freedom of the Herrscher of the Erosion in the New World. Taken by hatred, Higokumaru allowed Herrscher of the Erosion to take over her mind and spread its virus in a new form of disease known as Bubonic Plague. Her bubonic plague became an infection of the lymphatic system, usually resulting from the bite of an infected flea. The disease could be transmitted by direct contact with infected tissue or exposure to the cough of another human. Herrscher's flea was parasitic on house and field rats, and seeked out other prey when its rodent hosts die. The bacteria remained harmless to the flea, allowing the new host to spread the bacteria and gave a chance of Herrscher of the Erosion to spread all over Europe. The bacteria form aggregated in the gut of infected fleas and this results in the flea regurgitating ingested blood, which is now infected, into the bite site of a rodent or human host. Once established, bacteria rapidly spread to the lymph nodes and multiply.


Otto testing drugs in patients infected with the Houkai disease.

Medieval doctors had no idea about such microscopic organisms as bacteria, and so they were helpless in terms of treatment, and where they might have had the best chance of helping people, in prevention, they were hampered by the level of sanitation which was appalling compared to modern standards. Another helpful strategy would have been to quarantine areas but, as people fled in panic whenever a case of plague broke out, they unknowingly carried the disease with them and spread it even further afield; the rats did the rest.

In a matter of a few months, Herrscher of the Erosion had already infected half of Europe with the Bubonic plague, starting officially the Black Death and the Second Apocalypse, wiping out 1/3 of the world's population. There were so many deaths and so many bodies that the authorities did not know what to do with them, and carts piled high with corpses became a common sight across Europe. It seemed the only course of action was to stay put, avoid people, and pray.  To save Europe from the Houkai, the current Bishop of Shicksal allowed Otto Apocalypse and his doctors start human experiments with the Purple Box to seek out the truth behind the plague and put an end to not only the plague but also all Houkai creatures of the world.

When Kallen Kaslena discovered her best friend, Otto Apocalypse (who was still a good guy back then and became the story's Big Bad thanks to Herrscher of the Erosion), was perfoming human experiments to save mankind from the Houkai plague, she was arrested for discovering the dark secret of Shicksal. With the help of Otto Apocalypse, she later escaped and fought the paladin Eleanor Shariac who was taken by envy due to Kallen's relationship with Otto Apocalypse. During the fight, Eleanor injected the energy of the Purple Box  onto her body and was controlled by Herrscher of the Erosion for a short period of time, transforming her into a monstruous spider-Houkai creature. Otto Apocalypse then shot the creature and helped Kallen escape with the Purple Box from Europe. 

Arrival in Japan (Old Script)


A plague doctor using a fragment of the Purple Box in a woman to transform her into a monster.

In the old script (old manhua of Guns Girl Z), the Purple Box was not being controlled by the Bishop or Otto Apocalypse but was discovered by a small faction of doctors that studied the box and started the Black Death by accident. To rise above God, the leader of the faction used its power to transform humans, mainly heretics captured by the Shicksal to transform them into Houkai beasts, allowing them to create the supreme race under the control of God.

When the Purple Box was going to be transported to Europe in a boat of Shicksal Kallen Kaslana, a devoted nun of their sect couldn't hold her anger towards her leaders when she watched one of her comrades being transformed into a Houkai beast by a Doctor Plague and stole the Purple Box from the crew but had to fight her way through other nun protecting the Purple Box. She defeated most of the nuns but was wounded by a bullet and fell into the ocean with the Purple Box.

Days after, her body arrived in a Japanese village in Japan where she was rescued by the young Yae Sakura. During her rescue, the priestess Sakura opened the box and accidentally freed the Herrscher of the Erosion.

Arrival in Japan (New Script)

During her escape to Asian on foot, Kallen was severely injured by Shicksal's hunters and was rescued by the innocent Yae Sakura who found her by conscident in a nearby river. Like her old script, Yae Sakura opened the box by curiousity which freed he Herrscher of the Erosion and allowed her to take over Yae Sakura's body to use it as her new vessel. The Herrscher proceeded to self-call herself as Yakujin, the God of Disaster and infected Yae's memories to manipulate her emotions.

Yae Village's Curse

As the years passed, Yae Sakura and Kallen Kaslana formed a intimate relationship, something Herrscher of the Erosion planned to use in the future. At some point, the Herrscher of the Erosion cursed the village with plagues and scarcity of food and water, leading the villagers to adopt cruel methods to save their village; sacrificing children to the Gods to answer their prayers. Inside of her body, Herrscher of the Erosion forced Yae Sakura to kill children and infants in sacrificial rituals that were supposedly to be sacrifices to "please the Gods" when in fact it was only giving more power to Herrscher of the Erosion by causing the precious and loved children. 


Erosion feeding a Honkai monster with the kidnapped girl.

One night, Herrscher of the Erosion took over Yae's body and kidnapped a young girl from the village. In the forest, she tied up the girl in a tree and killed a bear that was just passing by before turning the animal into a Houkai creature and gave the defenseless girl to the Houkai to be devoured alive to strengthen the creature. One day later, Herrscher of the Erosion dispatched the creature to attack the village, killing dozens of men, women and children to force the villagers to sacrifice even more children for their safety. Before the creature could cause more damage, Yae Sakura put down the beast, passing the image of a heroine to give Yae Sakura more familiar power over the population.

The next night, Yae Sakura begun a sacrificial ritual but their ceremony was interrupted by Kallen who considered their ceremony heartless and inhuman. Annoyed by her presence, Herrscher of the Erosion transformed herself into a giant ghost fox and devoured the child before crushing her mother with her paws as "thanks" for their efforts. Kallen then faced the white fox creature in a deadly combat but before she could put an end to the creature a masked figure entered in the combat and chained her body. The masked figure said it was just normal for the villagers to be devoured by the God they worship. Angered, Kallen said the white fox was not a God but a Houka creature full of Apocalyptic energy. Kallen then shoots the masked figure and breaks their mask, revealing the identity of the mysterious person as Yae Sakura who was being controlled by the fox. The Herrscher of the Erosion then explains how she was freed from the box and blames Yae Sakura for everything she did so far due to her hatred for this village that sacrificed her young sister a long time ago. Herrscher of the Erosion then says she is going to destroy the village and destroy everything she and Yae loves the most to make the two suffer for being born human.


Herrscher of the Erosion devouring Sakura.

After devouring and killing all the villagers, Herrscher of the Erosion burned down the village as a "favor" to Yae Sakura. Arriving at the village, Kallen sees Herrscher of the Erosion seated on the top of a burning temple and challenged her to a death combat. Erosion accepted her challenge but stated she is not going to spare her life anymore. After a long fight, Herrscher of the Erosion overpowered Kallen and forces Yae Sakura (who is currently watching inside of her subconscious) to watch she killing her lover but before Herrscher of the Erosion could cut her in half with her katana Yae Skaura breaks out of her mind control and use the katana she was holding to commit suicide to prevent Herrscher of the Erosion from killing Kallen using her own body.

Enraged, the Herrscher of the Erosion returns to her Fox Houkai form and angrily hold her with her mouth while threatening to kill Sakura right in front of Kallen to show how much she is powerless before a "God". Sakura is then devoured by the Houkai beast while Kallen fought the creature in one last fight. Due to her immortality, Kallen Kaslana was forced to seal the creature inside of her own Judah stigmata where Herrscher of the Erosion and Yae Sakura would be kept sealed for the next 500 years. Inside of the stigmata world, the Herrscher of the Erosion altered its space and time and kept repeating the same day that Yae's young sister was sacrificed for 5 centuries to make her suffer even more for betraying her.

Mordern Era


Erosion disguised as Sakura's father to propose the sacrifice of another child.

In the modern era (2016 D.C.), when Theresa's Stigmata (Kallen's former stigmata) causes her to lose her consciouness, Bronya concluded something happened with her stigmata which was originally from Kallen (the deceased lover of both Otto Apocalypse and Yae Sakura 500 years ago). To investigate what happened, Raiden Mei is sent to Theresa's stigmata world where she meets a fallen Past!Kallen on the middle of a burning village that turned out to be Yae's village after Herrscher of the Erosion destroyed it.

Theresa then awakes inside of the stigmata world and meets Yae Sakura from that world. Knowing they finally had a chance to return to the real world, Erosion took the form of Yae's father and dispatched a horde of Honkai monsters to attack the village and devour the civilians alive to blame Theresa for luring the Honkai creatures to their peaceful village. In a reunion, Erosion (as Sakura's father) proposes sacrificing more children to protect their villages from the Gods' wrath but when Theresa invaded the room to rise her opnion about killing children, Erosion threw a rock at Sakura as a way to punish her from bringing such young girl to the village. 

Leaving of the room, Erosion discovered Theresa was Sakura's last hope and vowed to destroy her so they can be free again. They later had a chat with Sakura to taunt her about all the victims they killed 500 years ago, including remembering her of when she killed hundreds of children in the name of a God that didn't even exist when was in fact none other than Erosion themselves. At night, Erosion sent their women to capture a sleeping Theresa to sacrifice her. When she resisted, Erosion ordered to cut her both of her feet so she couldn't escape.


Erosion disposing Theresa after forcing Yae Sakura to kill her.

At the sacrificial ritual, Erosion revealed their plans to sacrifice Theresa so they can take over Theresa's body in the real world and escape from the stigmata world. When Yae Sakura refused to kill her, Herrscher of the Erosion invaded her mind and forced her to remember when she killed her own sister in a similar sacrificial ritual, while in her mind, Erosion controlled her body and impaled Theresa with her katana before disposing of her body. As Yae began to dissolve, Erosion embraces her they love her and now are going to drag her to an eternal nightmare.

In the real world, Erosion takes control of Theresa's body and happily laughs for finally being revived after500 years. They proceeded to attack Kiana and Bronya to celebrate their revival but was quickly knocked down by Theresa's will. With their defeat, Erosion returned to the stigmata and faced Mei in combat. During the combat, Erosion caught the sight of Theresa and Sakura and returned to their original goal of destroying their minds and taking over Theresa's body but a revived Kallen Kaslana appeared before them after 500 years dead. Without wasting time, Kallen began to seal the Herrscher again but before the ritual could success Erosion invaded Kallen's mind and searched for hatred inside of her memories.

There, they found the source of her hatred, Otto Apocalypse and used his form to corrupt her as one last resource to avoid being sealed, however, Theresa showed affection and love for Otto, refusing to fall for Erosion's temptation. With nothing more to do, Erosion accepts her fate of being sealed again for the time being.

Virtual World

Soul Throne Raid

Equipament - Florid Sakura

  • Demonblade - Florid Sakura.
  • Sakura Blossom.

Sakura Blossom is the weapon of choice of Herrscher of the Erosion's vessel, Yae Sakura, a japanese katana forged in the Yae village. It's a spiritual blade once enshrined in the Yae Jinjia to protect the village from Houkai beasts and sacrifice children to the Gods to be blessed by the divine beings.

While being a Herrscher who primarily uses bruth strength or mental powers to get what she wants, the Herrscher of the Erosion is not above using katanas and other swords to fight. When the Herrscher possessed Yae Sakura, she slaughtered many innocent humans using this weapon, tainting it to become Demonblade - Florid Sakura

After killing hundreds of children and babies with the katana, the crimson katana now radiates raw Honkai energy that strengthens the Herrscher of the Erosion.

~ Herrscher of the Erosion to her victim.
Ha... Ha... Ha... everything had just begun.
~ Herrscher of the Erosion seeing her dead monster.
Leave her body? It was she herself who sought for my help, I did absolutely nothing! Her heart is filled with hate towards humans. It was me who gave her the strength to realize her dream of wiping out all the humans she hated.
~ Herrscher of the Erosion about Yae Sakura.
I am the dark harbinger of your death, humans. I am the nightmare in all mortals that exist in this plane of existence. I am the 12th Herrscher who seeks revenge upon your inferior kond. I am your living nightmare. Your greatest fear. I am YOUR DEMISE!
~ Herrscher of the Erosion.
Do you want to come along too? Doing things on a whim will make you feel really good, you know?
~ Herrscher of the Erosion inviting Kallen to join her.
Erosion: I'll let you off this time on behalf of Sakura, she likes you a lot, you see.
Erosion: If I'm not going to kill you then at least I should do something else... Of course I am going to destroy everything you love and want to protect! HAHAHAHAHAHAHAHA!!!
~ Herrscher of the Erosion speaking to Kallen Kaslana.
Evil? I? You hurt me like that. What's so wrong killing humans? Why it's so bad making them suffer? Why it's so bad to crush their children like bugs? Why it's so wrong to cut their head off while they are alive? Why it's so wrong to make them suffer right in front of their children and lovers? They are toys! Toys! Get it right.
~ Herrscher of the Erosion showing her psychopathy.
Do you still resist me? Girl. Well, nevermind. If I kill you with Sakura's hands I can sever away Sakura's lingering attachments. Just then her body will be mine!
~ Herrscher of the Erosion threatning to kill Kallen.
You are too gullible, Kallen Kaslana. Are you still clinging to your childish delusions even at this point? Don't you get it?! The one who pushed Yae Sakura to the brink of despair again... was you, Kallen Kaslana!
~ Herrscher of the Erosion blaming Kallen for turning Sakura in a bad person.
Four years ago, she had lost her beloved sister. And endured four years of loniless and hardship... And she finally met you. Someone who was unrelated to the village and found warmth again. She thought she had finally found her own beacon of light. But that light chose to shine on others instead. In many dreams, she had dreamt of making you belong to her only. This is beautiful, right?
~ Herrscher of the Erosion explaining Sakura's backstory.
Miko-sama, you see the shadow of your little sister in this girl, am I right? But please remember... protect the village is your duty. This little girl is your last hope? Haha. After I destroy her, Sakura, soon... you will be all mine.
~ Herrscher of the Erosion as Yae's father.
Do you really want me to kill another child? I can do the same million times until you beg to me to stop!
~ Herrscher of the Erosion.
You are already out of time. The ritual will begin now!
~ Herrscher of the Erosion to Theresa.
Why I'm spreading so much pain? If they had the chance to make me suffer again, they would do it again. So I'll go beyond them and deliver in pain a thousand times worse. So why not?
~ Herrscher of the Erosion.
Finally! Once our offering is sacrificed, Yae Sakura's body and soul will be mine! Heh. Your feet have been severed, you can't even move anymore. What do you think you can do. In this dimension, you're nothing but a little girl.
~ Herrscher of the Erosion about to start the ritual.
Let me tell you a little secret. If your spirit die in this dimension, your body in the real world will die along with it.
~ Herrscher of the Erosion to Theresa.
I've lived for many millennia and I watched the rise and fall of different eras and nations. Humans always say they don't lik hate and evil but they still causes conflict to find peace. All evil will wipe out all living beings. And when I finish here? I'm just going to do it somewhere else...
~ Herrscher of the Erosion.
Killing may not stop nothing, but seeing your body rotting on the floor will bring a smile to my face.
~ Herrscher of the Erosion to Raiden Mei.
If you want a picture of your future, imagine a me ripping out your guts.
~ Herrscher of the Erosion.
Work for the Gods. Sacrifice for the Gods. This is a miko's duty. And I the God of your stupid race known as human! Now. KILL HER!
~ Herrscher of the Erosion ordering Sakura to sacrifice Theresa.
Are you still praying for the dead villagers? This place is so unfortunate... unfortunate indeed. Do you wish to protect this village? Isn't it obvious? The only thing you have to do to protect this village is to offer provide offering to the Gods as you once did!
~ Herrscher of the Erosion tormenting Sakura.
Let me bestow my tusks upon you! Let me bestow my blade upon you! Let me bestow my darkness upon you!
~ Herrscher of the Erosion to her vessels.
What, did you think I consider humans as ants? No. For me. They are not even living things.
~ Herrscher of the Erosion to Sakura.
I'm so happy. You finally recognized me! And to think it was you who personally sealed me into that box half a year ago... it's all thanks to this Sakura girl that I could break open the seal of the box and contine with my mission of cleansing this world of filth.
~ Herrscher of the Erosion controlling Sakura's body.

~ Herrscher of the Erosion to Kellan.
~ Herrscher of the Erosion, after taking over another host.
I'll use your deaths to celebrate my revival!
~ Herrscher of the Erosio after taking over Theresa's body.
~ Herrscher of the Erosion.
Hah! I can feel Houkai beast body composition mixed in this vessel. Insignificant humans dared to touch the realm of Gods? Even better, I'll be able to use all my strength now!
~ Herrscher of the Erosion.
I'll use your deaths to celebrate my revival!
~ Herrscher of the Erosio after taking over another host.
Unforgivable! You opposed me all this time, but what can you do with the mere strength of a human? Let me say it once more! You are powerless before me! Watch closely and despair! You shall never be reunited with this girl again!
~ Herrscher of the Erosion before devouring Yae Sakura.
All you had to do was to stay in my body and live an eternal dream! Why! Why do you resist?! Fine... If you want to die, I shall grant your wish! It's time for you to burn to ashes!

  • Higyokumaru and Sakura both share a fox-like motif, which is why Herrscher of the Erosion took the form a Nine-Tailed Fox as her primary form once she arrived in Japan.
  • "Higyokumaru's first half of her name is based in the name of the Higo Province (肥後国 Higo no kuni) that was an old province of Japan in the area that is today Kumamoto Prefecture on the island of Kyūshū. It was sometimes called Hishū (肥州), with Hizen Province. Higo bordered on Chikugo, Bungo, Hyūga, Ōsumi, and Satsuma Provinces.
    • In Japanese "Kuma" means bear, something that is not really related to her Kitsune-theme.
  • Sakura doesn't have Herrscher Core inside, just stigmata of the Herrscher of the Erosion only but she was a suitable vessel for her Herrscher, something that happens rarely.
  • In-universe, she is easily considered to be one of the most evil Houkai entity to have ever existed alongside the Herrscher of the Void and Houkai God who happens to be the Herrscher of the Void of the Old World.
  • The sacrifice rituals of children started by the Yae Village was heavily based in the sacrifice rituals of children in the name of the demon Moloch in the ancient times. Rabbinical tradition depicted Moloch as a bronze statue heated with fire into which the victims were thrown. This has been associated with reports by Greco-Roman authors on the child sacrifices in Carthage to Baal Hammon, especially since archaeological excavations since the 1920s have produced evidence for child sacrifice in Carthage as well as inscriptions including the term MLK, either a theonym or a technical term associated with sacrifice. In interpretatio graeca, the Phoenician god was identified with Cronus, due to the parallel mytheme of Cronus devouring his children. The Herrscher of the Erosion had the Yae Village sacrifice children in her name for power while "blessing" their village so she could keep with tha facade of being a God.
  • In the world of Honkai Impact 3rd, the Herrscher of the Erosion ignited the Black Death in 1470 while in the real world the Black Death broke out in 1347 to 1351.
  • The 12th Herrscher is the only known Herrscher who uses a katana as her weapon of choice. At the same time, it's the only Herrscher associated to the Japanese culture.
  • The Herrscher of the Erosion is the character with the third largest body count ever, with the total of 4 billions or more. Aside from that, it's the only Herrscher who had a more personal body count instead of committing disaster of large scale. While in Yae village, the Herrscher controlled Sakura and killed hundreds of children and infants with a single katana.
  • One of Sakura's skin, Moshinsou Memento is actually a character from an in universe video game called "Kallen Fantasy VII" made by Otto Entertainment. There, she's described as a runaway failed experiment who goes on a rampage until she meets Kallen.
  • The Herrscher of the Erosion is the only non-human Herrscher there is while many others started as humans. Herrscher of the Void for example is represented with human appearance while Herrscher of the Erosion is reprsented as a fox-demonic creature.
  • Like many others character, the Herrscher of the Erosion (both vessel and fox form) were underwent to a character re-design at the launch of Honkai Impact 3rd. Yae Sakura for example had her length of her ears reduced and had her tail removed while Hellmaru is way bigger and possess many japanese accessories.
  • In Honkai Impact 3rd, Sakura doesn't have a tail due to technical difficulties, unlike her first version of Houkai Gakuen 2 where she possess one.
  • The name "Sakura" literally means "cherry blossom" (桜), a flower which is cherished in Japan due to its beauty and its almost-tragically short life span (cherry blossoms have historically been associated with the samurai). It also serves as the national flower for the nation of Japan.
  • In her new form, Erosion becomes a Kitsune. Kitsune is the Japanese word for the fox. Foxes are a common subject of Japanese folklore; in English, kitsune refers to them in this context. Stories depict them as intelligent beings and as possessing paranormal abilities that increase with their age and wisdom. According to Yōkai folklore, all foxes have the ability to shapeshift into human form. While some folktales speak of kitsune employing this ability to trick others—as foxes in folklore often do—other stories portray them as faithful guardians, friends, lovers, and wives. Foxes and humans lived close together in ancient Japan; this companionship gave rise to legends about the creatures. Kitsune have become closely associated with Inari, a Shinto kami or spirit, and serve as its messengers. This role has reinforced the fox's supernatural significance. The more tails a kitsune has—they may have as many as nine—the older, wiser, and more powerful it is. Because of their potential power and influence, some people make sacrifices to them as to a deity. Conversely foxes were often seen as "witch animals", especially during the superstitious Edo period (1603–1867), and were goblins who could not be trusted (similar to some badgers and cats).
  • Tengen Toppa Gurren Lagann

    Tengen Toppa Gurren Lagann, the titular mecha of the series with the same name.

    The 12th Herrscher is the only Herrscher who has an animal-motif.
  • In earth science, erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location (not to be confused with weathering which involves no movement). Despite being called "Herrscher of the Erosion", it has nothing related to erosion but to plagues and fogs.
  • Her Jizo Mitami Samurai form is oddly similar to many mechas of the popular Tengen Toppa Gurren Lagann anime series that served as base to many other mecha animes and parodies in countless fictional works. At the same time, the legless samurai is very similar to Susanoo from Naruto franchise that is a gigantic, humanoid avatar made of the Rinnengan user's chakra which surrounds them and fights on their behalf. It is the strongest ability available to those who have awakened the Mangekyō Sharingan in both eyes. In Naruto, Sasuke Uchiha and Madara Uchiha are one of the few people who can summon the Susanoo avatar.
  • The Herrscher of the Erosion is the first villain of the franchise to have originated in the manhua while all others made their debut in the games.
