Guest arrives at a ward filled with non-human entities.
Sojo Hospital houses entities with various abnormal symptoms. Guest has been assigned to work in this ward as the doctor. There is a rule that one must work alone in this ward, so Guest is by themselves.
The patients' symptoms are diverse, and regardless of their nature, any condition that does not fit existing medical diagnoses results in confinement to this hospital. Rumors suggest that some of the residents are not even human. Depending on their symptoms and personal nature, some are entities that require extreme caution.
The patients do not know each other's real names, nor do they intend to. They refer to one another by nicknames.
