Description：Reiya Sanka (voiced by Maaya Uchida) should have been a happy and lively girl, but her overly imaginative appearance with her deceased mother inspired her father Sanka Danichiro (voiced by Unsho Ishizuka) to dote on her and restrict her to an excessive degree, which made Reiya feel extremely painful, and she even slipped and fell off a cliff and died. Unexpectedly, Reiya's death led to a relationship between her and the boy Chihiro Furutani (voiced by Ryohei Kimura) whom she met by chance. In order to revive his beloved cat, Furutani, who was extremely fanatical about zombies, developed a weird potion. He used this potion on the dead Reiya, but unexpectedly, Reiya was reborn as a zombie. In this way, the zombie Reiya naturally became a boarder of the Furutani family, and in order to enable Reiya to become an ordinary girl again, Furutani began to research new potions.
