Mjölnir

Mjölnir (ミョルニル) is a magician who was at first mistaken for a spiritual item but in actuality has optimized their physical body into various the forms of the hammer.

Etymology
The name Mjölnir is the name for the legendary hammer of Thor. It's kanji reading (雷神ハンマー), refers to its relationship with the god of thunder, Thor.

Appearance
Despite being called "The Hammer", Mjölnir has various shapes but its first and most prominent appearance is that of a cylinder made of heavy stone with a diameter of 55 cm and a height of about a meter. The other forms were a sphere, a cube and finally a flat plane in the shape of a cross into a hammer. Mjölnir appears to communicate and recite spells by having countless sets of human lips both large and small appeared on its surface.

Background
The magician apparently gathered up a lot of power for an unknown reason only to have lost it in its transition for power during WWIII. With the reason to obtain strength gone, Mjölnir continued to gain power and go on a destructive path. Marian Slingeneyer, another member of GREMLIN, is responsible for its current form as a cylinder.
