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 face plate of the Iron Maiden, to Jeanne's helmet and even a pair of iron bolts.

Babylon Gate
In the anime, Shamash is the key to opening the Babylon Gate, an inescapable portal to another dimension. This is how the X-Laws' plan to defeat Asakura Hao. Once it is opened, everyone, including Hao's team and Yoh's friends, are sucked into it. However, before the gate closes, the Spirit of Fire grabs Shamash and pulls it in with them, devouring him and gaining his powers, after which it easily broke out of the gate. Jeanne's attempt to seal away Hao fails and almost costs Jeanne her life.
