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.
I feel like I tell you all the time 
not to go off and do things on your own.
أشعر وكأنّني أخبركِ طوال الوقت ألّا
تذهبي بمفردكِ وتتصرّفي من تلقاء نفسكِ
Ständig sage ich dir, dass du nicht
auf eigene Faust losziehen sollst.
Estoy harto de decirte
que no hagas nada por tu cuenta.
Estoy harto de decirte
que no hagas nada por tu cuenta.
On te répète constamment
d’éviter de faire des vagues.
Mi sembra di averti detto più volte 
di non andartene in giro di tua iniziativa.
Eu já te falei para não sair por aí
fazendo as coisas sem avisar...
Я вроде не раз говорил
не позволять себе вольности.
