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.
We can't let Ito and the others 
find out about the Water of Life.
لا يمكننا أن ندع إيتو والآخرين
يعلمون بشأن ماء الحياة
Ito und die anderen dürfen nichts
über das Wasser des Lebens erfahren.
Ito y el resto no pueden
descubrir lo del Agua de Vida.
Ito y el resto no pueden
descubrir lo del Agua de Vida.
Itô ne doit rien savoir
sur l’eau de jouvence.
Non possiamo far sapere a Itou 
e ai suoi dell'Acqua della Vita.
Não podemos deixar que Itou e seus
aliados saibam sobre a Água da Vida.
Ни Ито, ни кто-либо ещё
не должен узнать про живую воду.
