Ichiha Kan'no

Fumiko and Chitose, the second and third sisters of three sisters, work as waitresses at a coffee shop. With her boyfriend's birthday approaching, Fumiko can't concentrate on her work, imagining that Tsutsuji, the eldest sister with bad habits with men, will seduce him. Suddenly, a man with a knife and a modified gun bursts into the shop.

Saburo runs away from home without telling his wife, Kyoko, that he was restructured. Saburo was given the name of Unkokusai when he was told by a mysterious priest, Chinkokusai, who appeared in front of him at a loss to become the same priest as himself. The husband and sister started living together from the married woman Shiori who met, and it is said that this is because the evil spirits possessed them, and they are invited to their home. A fake monk, Unkokusai, tries to enjoy the body of beautiful sisters as a reward.
