I read it somewhere that the mc really have a sister but that sister died a long time ago but the first wife of mc’s father have a contract to the devil so..... the soul inside the mc sister’s body is not actually the sisters soul but the devil. The devil want to destroy the world to do that he must kill the mc so that the god will be angry and abandon the world.
I read it a long time ago so if I am wrong please understand thank you
