Азазель

A tall and muscular demon with a serious demeanour, silver hair and brown eyes who used to be a Cherub. Despite his serious appearance he is actually extremely kind and friendly. He almost never speaks out loud, preferring to communicate with messages written on display boards. He secretly loves cute things like puppies and kittens and collects stuffed toys he keeps in his room, especially teddy bears. The only meal he will eat from the castles canteen is teddy bear pancakes. He is skilled enough at sewing that he can make his own stuffed animals, which he frequently is asked to do by Beelzebub, and is also able to bake his own cookies.

He has a crush on Belphegor and hates that his appearance frightens her and has tried several methods of making himself seem less scary. (Source: Wikipedia)
