Tenpou Ibun: Ayakashi Ayashi - Ayashi Shinkyoku

Mizuno has fallen from power and the Tenpo reforms are over, yet Edo remains in hardship. When retainers disappear on fishing trips in the bay, the Ayashi follow the case to Tsukuda Island and encounter a covert force serving the Tokugawa family.

Ogasawara is subsequently imprisoned for killing a fisherman. Behind bars, an old acquaintance tells him of a fiery creature called the Red Cat, while a worried Saizo enters the prison in disguise.
