A young looking boy with mint eyes and short black "emo" hair. He doesn't seem to care much about anything. Lonely, distant… hides his emotions frequently, however he’s a very loyal and caring friend. Has a certain affinity to darkness. His right arm seems to be burnt and always covered by bandages.

This bandages turn black with mint markings while Azoa makes use of his "Cursed Bandages" ability. If used for too long, it can burn him wherever the bandages touch his skin. Other powers of his include the capability of absolute control over shadows, as well as bending with them. However, if used on excess, it can led to an extreme tired state.

The human who summoned Azoa was called Mast. The reason of the summoning was... a deep wish to make a friend. Mast was chronically ill, and despite Azoa trying to refuse, he ended up agreeing to the pact. As a result, Mast gifted it's body and soul to Azoa, who followed the contract, making that body as his.
