Among the events in this OAV is included a fictionalized version of what became known as the Ikeda-ya affair, when in June 1864 the Shinsengumi in Kyoto raided an inn, the Ikeda-ya, being used as a hideout by pro-Imperial fighters. The alleged plot was to destroy Kyoto through fire, hopefully destabilizing the Shogunate's grip on the people. In the end, the Shinsengumi broke up the ring, killing 8, wounding another 4, and arresting 20. This made them national heroes in the eyes of the Tokugawa bakufu.
