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...
It's not like she found out the reason 
they've gone crazy for blood, right?
لا يبدو أنّها اكتشفت سبب تعطّشهم للدماء، صحيح؟
Sie hat nicht herausgefunden,
warum es ihnen nach Blut giert, oder?
No sabe el porqué
de su ansia de sangre, ¿verdad?
No sabe el porqué
de su ansia de sangre, ¿verdad?
Ce n’est pas comme si elle savait
pourquoi il était assoiffé de sang.
Lei non sa perché sono diventati 
assetati di sangue, no?
Ela não deve saber a causa
da sede de sangue deles, né?
Она же не знает,
что он свихнулся из-за крови.
