M "Morphe"

About

M is a killer who goes on a rampage in Ikebukuro one day, causing the deaths of 10 people before he is arrested. He is dubbed "M" by a fansite and has a mysterious interest in Madoka.


The source of his powers is unknown, but thought to have been developed through researching various esoterical philosophies from all over the world. He is capable of "bilocation", a technique where he can multiply himself and teleport the doubles to other places. He has been impossible to identify, having burned off his face and removed all his teeth.

He considers Madoka a kindred spirit, and the one to kill him.
