The biography of Himiko Toga from the My Hero Academia series.
Himiko Toga was born in her family as the oldest daughter of out of her siblings. At a very young age, she found a deceased bird covered in blood. Finding the dead animal both pretty and cute, she could not help herself but drink its blood. Later wanting to share her joy with her parents and make them happy, she presented the dead bird to them with a bloody smile. Her parents were upset with her twisted nature. Worried how society would view their daughter and how that would reflect on them as parents, the two subjected Himiko to Quirk reformation where she was forced to suppress her natural instincts and not develop her Quirk.
Since Himiko's admiration of blood was caused by her Quirk and a natural part of who she was, this only caused her instincts to grow. In middle school, she was considered to be a very bright and friendly girl by her classmates and teachers until she was found drinking the blood of a boy named Saito that she fell "in love" with. Everyone looked at her with nothing but horror and disgust and as a result, she ran away from her middle school graduation.
Since then, she has been on the constant run from the law and became a suspect of a series of serial blood loss cases. Her parents also publicly cut all ties with their daughter after the incident, claiming that she was always a lost cause and branded her as a "creepy demon child", trying to deflect blame on their parenting by claiming that she was just born bad.
Vs. Hero Killer Arc
Himiko Toga was one of the few villains gathering together to the League of Villains, once Stain and his ideology were made public to the media.
Final Exams Arc
Himiko first appeared at Tomura Shigaraki's base with Dabi as new recruits for the League of Villains. Here Toga expresses her psychotic desire to become like Stain and kill him. Tomura was not impressed by their praise of the Hero Killer, and tried to attack them out of spite, but his and their attacks were deflected by Kurogiri. Despite the hostile encounter, Tomura accepted them both into the League of Villains.
Forest Training Camp Arc
Himiko later appeared with a few other villains in the Vanguard Action Squad. Their objectives were to attack the U.A. students at the camp while they trained. During the attack, Himiko encountered Ochaco and Asui. She had a device that was being used to take blood from her targets. As the fight continued, Himiko held a conversation with Ochaco about a crush that she had. As the confrontation continued, Himiko retreated in the woods as the other U.A. students came to their location.
As she left the scene, she glanced at Izuku in his beaten up appearance from Muscular and blushed. She made it to the exit point of the forest where she waited for a villain to bring Katsuki Bakugou with them. Kurogiri appeared and he was able to help the members of the Vanguard Action Squad retreat from the scene and capture Katsuki.
Hideout Raid Arc
Himiko, alongside the rest of the league, kept Katsuki under them intending to make him join the League of Villains. With the help of the heroes and the U.A students, they were able to retrieve Katsuki from the villains. All For One also transported the villains out of the way to deal with All Might.
Hero License Exam Arc
After All For One's defeat, the League of Villains scattered all over the place, in order to stay hidden from the police. On her own time, Himiko took the DNA of a girl named Camie Utsushimi and infiltrated the U.A students during the Hero License Exam. From there, she encountered Izuku Midoriya and attempted to capture his blood, while also wanting to know more about him. Eventually, she managed to make her escape with his blood and went back to the League of Villains caught.
Shie Hassaikai Arc
Himiko reunited with everyone else in the league's new hideout. Twice brought over Kai Chisaki, believing him to be a new recruit, in which Himiko noted how different he is compared to them. When Chisaki departured with the Shie Hassaikai after a chaotic fight, Himiko asked if she could stab him, but Tomura refused.
Himiko and Twice were later briefly recruited as members of the Shie Hassaikai by Chisaki, after a meeting with Shigaraki. Before she meets up with Chisaki, she asks Tomura why she has to be stuck with partnering Chisaki. Tomura believes that she and Twice are capable and places his trust in them, assuring them with a smile.
When the heroes infiltrate and attack the Yakuza base, Himiko and Twice begin to make their move. As Mimic uses his Quirk to separate Rock Lock from his group, Himiko manages to fool him with a clone of herself made by Twice. She then sneaks up behind him and stabs him, sucking up his blood. When Aizawa and Mioriya arrive, Toga disguises herself as Rock Lock and attempts to play off as him. However, Aizawa was able to erase her Quirk, destroying her disguise. Aizawa then engages into a brief fight with her, having her wrapped around his cloth and pinned down. Himiko, however, was able to escape by maneuvering herself and get a stab in his shoulder. Aizawa manages to shrug her off after cutting her cheek with the knife she used. The two are then separated by Mimic once more.
Himiko eventually meets up with Twice, in which she helps keep his sanity stable by wrapping up his head with a bandage. Disappointed and uninterested in the Yakuza as a whole, Himiko abandons the group with Twice, ultimately wanting them to suffer in pain and humiliation. Eventually, the two managed to reach to the surface. Disguised as Midoriya, she falsely leads the heroes to Chisaki and Eri's location. Planning to capture Eri, she and Twice send a clone of Mr. Compress to capture her with his Quirk, but ultimately fails. Later on, she and Twice watch as Midoriya battles Chisaki at his full potential, remarking at how strong he is.
After Chisaki's defeat and arrest, Toga wanders around the street with Twice (who is still trying to maintain his sanity together). She then comes in contact with the real Mr. Compress and helps guide him to where exactly Chisaki is being escorted to. Mr. Compress reveals what he and the rest of the league plan to do with him, much to her pleasure.
Meta Liberation Army Arc
After leading a massacre on the Creation Rejection Clan, Himiko and the other villains continued to keep a low profile while at the same time Tomura tried to get in contact with All For One's doctor. Himiko later takes part in a battle with Gigantomachia, who was seeking for the league to see who the successor of All For One is. After a brutal beating, Himiko and the rest of the league are taken away and introduced to the doctor, who addresses himself as Daruma Ujiko. After a conversation between Daruma and Tomura regarding his convictions, the league is sent back to deal with Gigantomachia.
A month has passed and while Tomura, Compress and Twice battle Gigantomachia, Himiko scouts the area with Spinner. When Spinner asks why she still remains with the league, despite their ideals not matching with Stain's, Himiko replies to him that he simply loves Stain and wishes to become the people she loves. Eventually, the two meet up with the other villains again and headed out to the city after Tomura received a phone call from Rikiya Yotsubashi to save Giran.
With Dabi later meeting up with the league, they headed out into the city where they encounter Rikiya's army and are forced into a battle with them. Himiko in particular battles one of the main executives, Chitose Kizuki, who exploits Himiko's past and her true nature through an interview, while at the same time putting her through a brutal battle. Eventually, Himiko shifts her face to that of Ochaco's and tags Chitose, as well as her followers. She then activates Ochaco's Quirk, causing them to float then releasing them, causing them to drop on the ground in a bloody mess.
Himiko later fled the scene in order to recover from her injuries but collapses from fatigue and blood loss. Twice eventually discovered her, who believed she was on the verge of death. He attempted to escape with her, but is prevented from doing so when Skeptic summons a clone group of Twice to capture the two. The clones attempt to kill Himiko while at the same time try to recruit Twice to join the Meta Liberation Army, but Twice eventually regains his sanity and forms a clone army of himself to save Himiko. Twice then measures and clones Himiko in order to perform a blood transfusion to save her life, whilst Twice's other clones go to assist the League.
Toga later recovers from her injuries at the hospital, revealing to Twice, who was mourning at a picture of her, that she is very much alive. She later watches Re-Destro's speech and comments on Tomura still having one of his hands (the only one that survived). Himiko and the rest of the League then walk to the stage as the League of Villains and Meta Liberation Army unite to become the Paranormal Liberation Front, with Himiko becoming a lieutenant of its Carmine Regiment.
Endeavor Agency Arc
A while later, Himiko fully recovers from her injuries with her eye remaining intact. She is present at Hawks' report that Endeavor would be taking on two new interns and she muses on one of them being Izuku, she soon thanks Hawks for the report and discusses their goal alongside the rest of her allies. Himiko then brings up Tomura's plan to destroy everything once he gains a handling on his powers.
Paranormal Liberation War Arc
After four months, Himiko is assigned as a commander of the Carmine Regiment alongside Skeptic, despite not liking him for trying to kill her and Twice. The villains are initially unaware of the heroes raid until they see the Gunga Mountain Villa mansion splitting apart and destroyed by Cementoss' Quirk.
Unprepared for the attack, the Paranormal Liberation Front send their lower-ranked soldiers to fight while the lieutenants evacuate. Himiko and Mr. Compress end up getting ambushed and nearly captured by a hero who restrains them both with his Quirk. However, Twice arrives and kills the hero with a knife to the back of the head. As the two villains get back on their feet however, Twice explains that he is unable to create anymore clones and begins melting, signifying the original Twice's death. Twice's clone approaches Himiko and gives her handkerchief back that she used to patch up his mask back at the Shie Hassaikai Raid, while explaining that Hawks had betrayed them and apologises for trusting him. Realising her friend has perished, Himiko embraces the clone and thanks Twice for saving her life.
Enraged by Twice's death, Himiko disguises herself as the same hero who attempted to capture her and goes on a blind killing rampage, slaughtering every hero in sight. She laments that it is hard to live and that all she wants is a world where she can be her, and that the heroes keep taking everything away from her. As Himiko's disguise wears off, Gigantomachia retrieves her and the other PLF lieutenants.
Following Tomura's orders, Gigantomachia heads for Jaku City while attempting to throw Mt. Lady out of the way. During this, Himiko and the others comment on what had just happened but the behemoth soon grabs all of them. The students of U.A. manage to subdue Gigantomachia while Red Riot climbs up the giant's arm and prepares to throw a sedative into his mouth, Himiko reacts quickly and throws a knife which shatters the sedative. However, Red Riot reveals to have another jar of sedative and throws it to the giant's mouth.
As more Pro Heroes join the battle, Gigantomachia manages to overwhelm the opposing forces and tears through multiple cities while destroying everything in his wake as the remaining PLF members follow behind.
As Gigantomachia presses forward, Mr. Compress sees Himiko viewing the distance and deduces that she is searching for "those U.A. scamps [she] loves so much." Himiko questions as to where heroes draw the line and asks if Twice was not considered a person in their eyes and if they plan to kill her as well. She then goes to find Midoriya or Uraraka to question them, despite Compress warning her of the dangers. Spinner speaks up saying that she isn't the only one who is shocked over Twice's death and tells her that although that doing as one pleases is "the villain way", that she should come back to them safely. Himiko thanks Spinner with a smile.
Himiko soon finds Uravity and Froppy, using her Quirk she disguises herself as an elderly woman and pleads for Uraraka to help her trapped husband. As Uraraka follows Himiko and comments on how fast this old woman can run, she replies by saying that she loves her husband. Himiko soon drops her disguise, much to Uraraka's shock and leads her into an abandoned house.
Himiko comments on how cute Midoriya and Asui are while the zero-gravity hero searches for her. Fully-clothed, Himiko ambushes Uraraka from behind and holds her down while questioning Uraraka as to what they plan on doing with her. Ochaco incredulously asks her if she lured her all the way out just to ask her that, and questions if she killed the old woman she disguised as for her blood. Ochaco angrily says that she wants to save as many people as she can and that if Himiko gets in her way, she won't hesitate to apprehend her.
Himiko glares at Ochaco in response as the latter manages to throw her off of her. Himiko comments that she is much stronger than last time, she then charges at Uraraka while explaining her way of thinking that she loves others and is unable to resist seeing them bleed out but knows that others don't think like her and can't accept her as a result. Because of this, Himiko finds it hard to live in society. She then explains how used Ochaco's Zero Gravity Quirk against Curious and her underlings, murdering them all in the process. Uraraka is horrified at this information and attacks Himiko with her wires only for Toga to dodge and strike back at her, knocking Uraraka into another room then wrecking everything inside. Uraraka stands up in anger, saying that she'd never use her Quirk to kill anyone and demands to know why Himiko wanted to talk with her.
Uraraka then notices Himiko pick something up and, much to her horror, realises that its the All Might keychain Izuku gave her for Christmas. Uraraka pursues Himiko around the house, demanding for her keychain back. Himiko questions as to if it's something precious to her which Uraraka confirms.
Himiko then mentions that Twice was somebody she cared about as well, and sees that Uraraka is the same as her for liking Izuku, who Himiko correctly guessed gave her the keychain. Uraraka retorts she has chosen to push those feelings down as she uses her new Super Move: Zero Satellite to drop wires and objects down on Himiko. Himiko dodges Uraraka's attacks and responds by saying that she has been doing the same since she was a child and that suppressing her feelings only made them grow further. Ochaco replies by saying that if the way Toga chooses to live harms people then she must also live with the consequences. Himiko responds by saying that she thought so, as tears begin to form in her eyes, which catches Uraraka off-guard.
Toga prepares to throw her knives at Uraraka, but Tsuyu storms in and strikes Himiko with her tongue. Tsuyu asks what Toga is doing here but the three are all distracted when Gigantomachia's movement makes the house shake. Himiko takes this opportunity to escape while Tsuyu prepares for if she plans to attack them again. Uraraka confirms that she ran away however, as she picked up her keychain left on the floor and wondered why Himiko was crying.
