At the same time, they were tasked with protecting Shogun Iemochi during his visit to Kyoto, prompting Hijikata and others to investigate. Meanwhile, several rasetsu escape the Shinsengumi with the help of someone resembling Chizuru. Chizuru, who had gone to the city with Sakai, becomes involved in the events and goes missing. The Satsuma domain learns of a plot by Tosa domain ronin to assassinate the Shogun, prompting Kazama and others to travel to Kyoto.
