Sinopsis

Shiro has died temporarily but is told by a mysterious person called "Kanrinin" that he can do a "homestay" i.e. his soul to reside in another dead person's body so as to find the reason for the latter's death. However, Shiro has to do this within 100 days or else his true form will be exposed and he will die for real.
