This museum allows the visitor to use high-tech virtual reality to reconstruct a realistic Edo of the Bakumatsu period. However, once the simulation begins, Tokidoki is attacked by a strange creature. After something happens to his left eye, he realizes that he is not wearing the VR goggles - it is no longer a simulation; he's trapped in the virtual world and has no way of getting back.

When Kuchiha is threatened by some samurai, Tokidoki stands up to fight them, only to have Kuchiha save him in the end, by exposing her secret: she's an inugami-tsuki possessed by a dog spirit. The samurai flee for their lives and Kuchiha gets mad at Tokidoki for having interferred in the first place. Unable to let the samurai get away, Tokidoki convinces Shinonome and the watchman, Heihachi, to help him pull a prank on one of the samurai to teach them a lesson.

When Ginshu left, a tengu, which was thought to be a bird by Kosen, spoke to him. Back in the present, Shinonome was in the kitchen, chatting with Kosen on how he was treating Kuchiha like a human despite knowing she was possessed by an Inugami.
