HAAHAHAHAHA HE RECALLED HIS PAST LIFE 💀💀 KNOCK HIM OUT MAI!!! (っ•`Д' •)っ

He didn't. In the og story mai was the first to die, so he could use her as his substitute(to make it as if was the one who died so he could carry out his plan), but in the panel here there were other people that were dead.

Ohhhh :0
