Kegare

A patient trapped in a coma discovers he can leave his body and temporarily possess other people. Using this ability, he begins to inhabit the bodies of nurses and other patients, indulging in sexual encounters while also taking revenge on doctors who mistreat the hospital staff.

However, each time he uses his supernatural power, it comes at a cost. As he continues to abuse his ability, the consequences grow more severe, threatening his own existence and the lives of those around him.
