Journal of the Mysterious Creatures

Synopsis

The work centers on Ren Hao, a 23-year-old man who has no job or girlfriend. In order to make ends meet he rents out one of the rooms in his house. While he’s showing Lili, his first tenant, around the house, she’s suddenly attacked by a vampire named Vivian, and Ren Hao notices that Lili is actually a werewolf. As Ren Hao and Lili start living in the same house, Ren Hao is scouted for an organization that maintains order of the parallel universes, and strange creatures one after another become tenants in his house. source: anilist.co
