Shamash

Shamash(シャマシュ, known as "Mash" in the English Anime) is a Kami-class spirit and the guardian ghost of Iron Maiden Jeanne.

About
Shamash is the Babylonian god of justice and Jeanne's guardian ghost. He established the ancient laws concerning justice, seasons and wars in Mesopotamia as their sun god. In one of their religious pilgrimages, the X-Laws found a sacred place within an old church. Jeanne obtained Shamash when she broke the spell that had sealed him there. He's an omnipotent Kami Class spirit, but he seldom does anything because the human world appears boring and dumb to him. He usually stands there with Jeanne just to instil respect, and only occasionally does he show his strength. When he eventually does, Shamash can be used to manifest various torture tools depending on which intermediary object is used. The mediums can variate from the Iron Maiden, to Jeanne's helmet and even a pair of iron bolts.

Shaman Fights Second Round
When fighting against Anatel Pokki, Jeanne uses Shamash to kill him and his teammates.

After Tao Ren is killed by Peyote Diaz, Shamash revived him by kissing him on the lips.
