This guy who can posses peoples bodies, possesses the body of a girl who was given the same power. They were both told to kill these people by making the body kill itself. They never really explained how they got the power or how they knew what to do, all they knew was that they had to kill these people. And if they didn’t kill these people then they would just be replaced, and they would be the first person their replacement inhabits. He becomes this girl, sees who she is and what she does and decides not to kill her. idk what happens for the rest of it bc that’s all i rmbr but i know that at some point there’s some other guy that comes to get them and kill them. (and i think he’s related to the mc but i’m not sure) h4s6t

It may be Aozora to Kumorizora (Azure and Claude)

IT IS THANK YOU SM!!!
