Villain Overview

A vile man who betrayed, and tried to erase me, his partner. That's your father's true form, boy!
~ Vail speaking to a young Ikki while possessing Genta.
I exist for no purpose other than serve you. I will do anything to get revenge on the devil killed your parents, buddy.
~ Vail speaking to Junpei after their first battle.

Vail is the secondary antagonist of Kamen Rider Revice. He is a demon who was originally tied to Genta Igarashi before it came to inhabit the Demons Driver, the transformation belt used to transform into Kamen Rider Demons. The Demons Driver was initially used by Fenix Squad Leader Hiromi Kadota, who was unaware it housed a demon and Vail that was feeding on his life force every time he transformed. He is also Vice's arch-enemy.

Vail would later exit the Demons Driver and return to its original host of Genta Igarashi, using him and the Vail Driver to transform into Kamen Rider Vail.

He is voiced by Kenjiro Tsuda, who previously voiced Redyue in Kamen Rider Gaim and also voiced Seto Kaiba in Yu-Gi-Oh.


As a inner demon to Junpei Shiranami/Genta Igarashi, Vail express joy when it first speaking with Junpei, desire to help him with his revenge; however this changed after Junpei changed his name into "Genta Igarashi" and down for a family, making Vail believe its closest partner choose to abandon him, thus leading to grow hates Yukimi Igarashi, which extended to their child's too.

It is also very manipulates towards others to achieve his personal objectives, while it will allow anyone to use the Demons Driver, their life force will be devour by it as does not relate to them in a personal matter, as well as prevent them from using multiple Genomix forms. When Olteca lost to Holy Live, Vail mocked him for his defeat, showing it does not tolerate failure.

However, after being unlocked to his full strength by Dr. George Karizaki, Vail immediately possesses Genta and uses him to attack his children.



Vail's birth came about when NOAH scientist Masumi Karizaki was delivered a man who had been fatally injured. To heal him, Masumi performed an experimental treatment by infusing his patient with cells he had extracted from Giff's casket, resulting in Vail being born. Vail was then awakened by Agariyama and used to kill Junpei's parents, to give Junpei hatred to motivate him so NOAH could use him as an "exterminator" for their failed experiments. Vail coaxed Junpei into using the Vail Driver, resulting in him gradually losing his memories from the strain of using the Driver. Junpei later escaped and was found by Yukimi, who gave him the name "Genta". Genta was soon recaptured by NOAH along with Yukimi, but now desired to leave NOAH and be with Yukimi and escaped again. However, Vail was able to trick Genta into setting him free, revealing his true form to Genta and that he was the demon who killed his parents. Vail possessed Genta to make him become Kamen Rider Vail again and go on a rampage, but Yukimi was able to reach out to Genta and get him to resist Vail. After killing Agariyama, Vail fought Genta, who became Kamen Rider Vail again and vowed to kill Vail even though that would result in him dying as well. Genta was able to defeat Vail, but before Vail died he was sealed in the Demons Driver by Masumi, allowing Genta to live.

Genta Igarashi would go on to marry Yukimi and have three children, all of whom inherited Giff's cells and developed their own inner demons as a result of Vail's ties to Genta. While Yukimi was still pregnant with her and Genta's third child, Vail possessed Genta and used him to set fire to the Igarashi family bathhouse in an attempt to kill them all. It was at that moment that Vice manifested from within a young Ikki and formed a contract with him to protect his family, with Vice wiping his memories of the incident in the process. Genta was then able to resist Vail and save everyone, but kept the true circumstances of the incident a secret from his children.

At some point, Vail met George Karizaki and was inserted by him into the Demons Driver he had been developing, which would allow any human to become a Kamen Rider regardless of if they had an inner demon or not.

As the Demons Driver

The Demons Driver was given to Hiromi by George Karizaki, who did not tell him it carried a demon within it. Hiromi initially used the belt to transform into Demons to fight Kagero, but he was unable to use the belt's full power as would feed on his life force every time he transformed. The effects of the Demons Driver became apparent when Hiromi was examined by Fenix medical officer Akemi Mikoshiba and discovered to have the physicality of an 80 year old man, despite being in his twenties. At the same time, George and Hideo Akaishi observed that the demon inside was about to awaken from Giff's pulsations.

The Demons Driver is revealed to be possessed by Vail.

Soon after, the Demons Driver would speak to Hiromi for the first time and reveal itself as a sentient demon that was feeding on his life force. This prompted Hiromi to confront George Karizaki on the effects of the Driver, to which George nonchalantly mocked Hiromi's catchphrase of laying down his life to save the world.

The Demons Driver was later stolen by Olteca during his escape from Fenix Skybase, who used it to transform to fight Kamen Rider Live. Upon his transformation, Olteca was acknowledged by the Driver as being a fellow demon. Unlike Hiromi, Olteca was able to draw out the full power of the Driver as Kamen Rider Demons, effortlessly defeating Kamen Riders Live, Revi, Vice and Jeanne.

Olteca would later use the Demons Driver again to fight Jack Revice and Jeanne. During the fight, Olteca attempted to use three Remixes but was blocked by the Driver. After being defeated and fleeing, Olteca angrily demanded to know why the Demons Driver hadn't let him use three Remixes, believing Karizaki had tricked him. However, the demon within the Demons Driver then spoke to him and revealed it was the one who had blocked him, before leaving the Driver to "return home".

Returning to Genta

Vail then possessed the new Driver Masumi Karizaki had been working on and used it to speak to him. Masumi warned Vail not to touch his son, but Vail asked why he should take orders from him and remarked that Karizaki was his one and only partner before leaving. He later possessed Genta Igarashi to intervene in the fight between the Deadmans and the Kamen Riders. Showing up right after the Queen Bee Deadman had blown the Riders out of their transformations, Vail used his own Driver to transform into Kamen Rider Vail and easily swatted the Queen Bee Deadman aside, knocking Aguilera out of her transformation. An awed Olteca sent more Gifftarians, to which Vail destroyed them both and allowed Giff to absorb their energy. Vail then turned to the Igarashi siblings and attempted to kill them, but Genta was able to resist Vail and cancel their transformation before collapsing to the ground.

Vail's ethereal form.

Following Giff's reawakening, Vail would approached Hideo Akaishi and ask him why he hadn't made a move yet despite Giff returning, to which Akaishi answered that human society comes with its own set of "processes".

Vail later met with Akaishi again after he captured Akemi. Akaishi opened a portal to Giff, who bestowed onto Vail a physical body. After remarking that the air tasted better than he expected, Vail left to go hunt for Genta. Vail approached Ikki while he was watching his sister play with Aguilera at an amusement park. He demanded Ikki tell him where his father was, but Ikki refused, leading Vail to declare he would beat him to a pulp and get his sister to tell him instead. Ikki and Vice transformed into Kamen Riders Revi and Vice to fight Vail, who battled them with his physical form. After going through several forms, Ikki and Vice merged together into Revice and performed their finisher on Vail, pushing him back. Vail then declared that they both had a long way to go to get stronger before teleporting away.

Vail would then attempt to attack Yukimi as she was shopping, but Vice, who had gone with her to protect her, fought Vail to protect her. As the two demons faced off against each other, Vail claimed to Vice that Ikki would at some point abandon him and that it was the destiny for all humans to eventually leave their demons. As they were fighting, Yukimi called Ikki and asked him to come help. Ikki soon arrived and transformed both himself and Vice into their Kamen Rider forms before fighting Vail. During their fight, Vice hesitated, allowing Vail to overpower both him and Ikki. After forcing both of them out of their transformations, Vail told Vice to think on what he had said before choosing to exit the scene rather than finish either of them off. Vail would later appear as the Kamen Riders were attempting to defeat Hideo Akaishi to fight the Riders alongside the True Gifftarians.

While Vail had the Riders at his mercy, he soon began to run out of power. It was at this point that, Akaishi closed the portal to Giff and teleported himself, along with Vail, Giffdemos and all of the True Gifftarians, away. Akaishi later met with Vail and stamped him with several Vistamps to power him up, but told him not to kill any of the Igarashi siblings. Vail asked what would happen if he did, to which Akaishi answered that their arrangement would come to an end. Vail then agreed not to kill them and stated he would beat them within an inch of death instead before teleporting away. When Daiji Igarashi and his siblings crashed a Fenix press conference in an attempt to kill Akaishi, Vail and several True Gifftarians appeared to fight them. Aided by Giffdemos, Vail was able to decisively defeat the Riders, but before he could finish them off, Hikaru Ushijima appeared, transformed into Kamen Rider Over Demons and rescued the Igarashi siblings before exiting the scene with them.

Vail would later confront Sakura again to get her to divulge her father's location to him, but Sakura refused and became Kamen Rider Jeanne to fight him. Vail beat her down, prompting Hana to intervene and try shooting Vail. Vail turned his attention to her, but Tamaki suddenly threw himself in the way to defend Hana. Vail decided to capture him instead and leave, so he could use him as a hostage to get Genta to reveal himself. Vail exited the scene and brought Tamaki to his hideout, where he tied him up and interrogated him as to where Genta was, but Tamaki claimed not to know. Sakura then showed up to rescue Tamaki and hand him the Week Endriver to transform with. Before Tamaki could insert his Vistamp into the Driver however, Vail swiped it and stamped it on himself. It was then however that Hana appeared and swiped the Driver before using it to transform into Kamen Rider Aguilera. In her new Kamen Rider form, Hana was able to beat down Vail and force him to retreat.

Vail would later intervene in a battle between Weekend and Fenix's demon forces, prompting Revi and Vice to show up to oppose him. Vail fought the two, but during the fight his body began to deteriorate, causing him to retreat. Vail returned to the ARARAT HQ, where he accused Akaishi of lying to him for saying Giff's grace would make him immortal. Akaishi simply stated that Vail should have known he was living on borrowed time when Akaishi found him 25 years ago and that his body was only temporary. With a limited amount of time in his lifespan, Vail resolved to use it to finally settle his grudge against Genta by killing him and joined the Fenix forces in another attack on Weekend. Akaishi accompanied them this time and transformed into his Giffdemos form to do battle. Vail and Akaishi fought Vice and Revi respectively and were beaten back by them. Although Akaishi broke away from the fight, Vail stayed behind to fight both Kamen Riders, even as his body began to wear out again. Despite this, Ikki did not want to kill him as doing so would also kill his father. It was then that Masumi Karizaki appeared with a WeekenDriver equipped and a Tricera Vistamp in hand, declaring he would settle his old sins.

Vail then swiped the Vistamp and stamped it on himself so he could continue fighting Revice, only to suddenly be teleported away to a parking garage. It was there that Masumi approached him again and offered him the Crimson Vail Vistamp. Vail at first refused it, believing it to be another trap, but Masumi told him it would be the only way he could fight Junpei again and convinced him to accept it. Vail then went to confront Genta to finally settle his score with him. Daiji and Akaishi both showed up to intervene in the fight, but Ikki and Sakura transformed into their Rider forms to hold them off while Genta and Vail faced each other. Vail asked if Genta worried at all about his family, but Genta responded that he didn't anymore and that his children had become far stronger than he ever was. Vail and Genta then transformed into Crimson Vail and Kamen Rider Destream respectively and duked it out. Destream managed to defeat Crimson Vail, but before Vail could disappear, Destream grabbed the Crimson Vail Vistamp and used it to seal Vail within him. Vail then spoke to Genta, who offered him a chance at a new life. Vail asked if Genta would truly allow him to do that given everything he'd done, to which Genta told Vail he would happily forgive him. Vail however told Genta he still hadn't forgiven him before dissipating into Genta's body, no longer at the stage where he could be a threat.
