Katsura Kogorou

A key anti-shogunate figure, who historically played a key role in the Meiji Restoration.

She has mastered the Shindō Munen-ryū school of swordplay, and possesses a sharp and intuitive mind. In spite of her remarkably venomous tongue, she is a revered figure among the anti-shogunate faction. Due to the time slip, it becomes Suguha's responsibility to prevent her from being assassinated by the Shinsengumi, so that history will not be altered.
