He has a fair complexion (rather normal). He is of a rather normal build (neither too thin nor too well built, just right). He also has a dark mustache (the same color as the hair), (with that mustache it's so unofficial, I might change it).
In demon form, he doesn't change much. He has horns on his head, wings grow from his back, and he has longer tusks and claws. His eyes also change color to a different color.
(here it is an unofficial look as he may be different in this form)He has the contract sign on his right hand, on the back side. It is a red and white pentagram.
His death scythe is specific. It is a combination of several types of weapons into one.

Dislikes: unnecessary harm to others, disobedience, inappropriate treatment of him
