Miho Kirishima is a central character in the alternate storyline presented in the film Kamen Rider Ryuki Episode Final. She is a con artist who seduces wealthy men to steal money and valuables, a livelihood she adopts to fund the cryogenic preservation of her older sister's body. Her sister was murdered by Takeshi Asakura, the violent Kamen Rider Ouja, and Miho enters the Rider War with two intertwined goals: to resurrect her sister by winning the conflict and to personally kill Asakura for his crime. Her motivations are therefore rooted in grief and revenge, and she is willing to employ any means, including deception and manipulation, to secure victory. Despite this ruthless exterior, she develops a begrudging fondness for Shinji Kido after they meet while she is attempting to swindle a man. She initially tries to steal his Rider deck out of desperation but gradually begins to show genuine kindness toward him, and a brief romantic tension forms between them. In the story, Miho is one of the six remaining Riders given a three‑day deadline to settle the war. She confronts Asakura multiple times but is outmatched in combat. With the help of Kamen Rider Ryuga's intervention, she manages to destroy Asakura's Advent Deck, causing him to disintegrate in the Mirror World. Later, she is deceived by Ryuga, who impersonates Shinji, and attacks her. She transforms into Kamen Rider Femme and fights Ryuga but suffers critical injuries. Shinji, as Ryuki, arrives too late to save her. Her final moments are spent hiding her wounds, sharing a smile with Shinji, and apologizing to her sister for failing to bring her back. As Kamen Rider Femme, Miho uses the Advent Deck bonded with the swan‑themed contract monster Blancwing. Her Visor is a rapier called the Blanc Visor. Her abilities include summoning Blancwing, the Wing Slasher twin‑blade naginata, the Wing Shield, and the Final Vent technique Misty Slash, in which Blancwing creates a gust that propels the enemy into her slashing weapon. Her fighting style emphasizes agility and the ability to engage multiple opponents, though she is physically weaker than some other Riders. Her character arc moves from a cynical, revenge‑driven fighter to someone who experiences genuine connection and sacrifice, ending in a tragic but dignified death.
