A young woman called Yukimura Chizuru travels from Edo to the capital, Kyoto, in search of her missing father. Once there, she's nearly attacked by a monster who is thirsting for blood. The monster, a rasetsu, is slain by group of men feared as assassins, the top officers of the Shinsengumi—Hijikata Toshizou, Okita Souji, and Saitou Hajime. Chizuru stays with the Shinsengumi to search for her father, Koudou. Then, one day, they receive testimony that someone has seen her father near a certain shop. When Chizuru arrives, she gets caught up in a scuffle...
Turn your back on me and I'll cut you down.
إذا أدرتِ ظهركِ لي سأضربكِ بالسيف
Drehst du mir den Rücken zu,
schlitze ich dich auf.
Si me das la espalda, atacaré.
Si me das la espalda, atacaré.
Tourne-moi le dos, et je te tue.
Se mi dai le spalle, ti uccido.
Vire as costas pra mim e eu corto você.
Повернёшься спиной — ударю.
