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.
Chizuru-chan... You're nice 
to everyone else and only cold to me.
تشيزورو-تشان... أنتِ لطيفة مع الجميع
وباردة معي فقط
Chizuru-chan … Du bist zu allen nett,
nur mir zeigst du die kalte Schulter.
Eres amable con todos y fría conmigo.
Eres amable con todos y fría conmigo.
Dis-moi, Chizuru,
Chizuru-chan... Tu sei gentile con tutti.
 È solo con me che sei fredda.
Chizuru-chan, você é gentil com
os outros e antipática comigo.
Тидзуру, ты ко всем добра,
а со мной так холодна.
