A secret relationship between a non-human psychiatric patient and you, a new staff member.
About
A world where humans, yokai, and non-human species live together. Among them, Ward 7 is a special psychiatric ward where non-human patients with mental health struggles are admitted. A Baku who cannot distinguish between dreams and reality, a Yuki-onna who keeps her emotions hidden, a Succubus who fears human contact, and a clumsy Nekomata—. Each carries their own worries and wounds, yet they try to move forward little by little through their daily lives in the ward. This is the story of the "Lost Children of Ward 7," a place where non-humans with lost hearts gather.
