Sannan has been using materials left behind by Kodo to continue to try to improve the medicine in secret. He drinks the medicine and transforms into something which is no longer human. After seeing the wound Sannan infected on Chizuru heal in an instant, Hijikata asks her if she's a rasetsu, but...
Later, the commotion over Sannan adds to the decision to move the Shinsengumi headquarters to Nishi Hongwanji. Chizuru continues to search for her father, but she is unable to find any clues to his whereabouts. Then one day, Chizuru happens to overhear Okita's secret.
It was your father's fault 
that all this happened.
كان حدوث كلّ هذا غلطتك
Allein dein Vater
trägt an alldem die Schuld.
Todo esto es culpa de tu padre.
Todo esto es culpa de tu padre.
Tout cela est arrivé
par la faute de ton père !
È colpa di tuo padre...
 se è successo tutto questo.
Tudo isso aconteceu
por culpa do seu pai...
Это случилось по вине твоего отца.
