Houkouin stands as one of the most chilling antagonists in the series, pledging her blade to Hitotsubashi Shigeyoshi while maintaining a clandestine partnership with the Shinsengumi. A warrior of exceptional skill, she takes the helm of a devastating Steam Puppet to crush any who dare oppose her masters. Her speech carries the refined, lilting cadence of an oiran courtesan, and her beauty is as captivating as it is deceptive — beneath that elegant facade lies a deeply fractured psyche and an insatiable hunger for violence, making her one of the most unpredictable and perilous figures in the story.
