I was debating whether to upload Unrah with his demon form, but I decided that I might as well, seeing as I'm pleased with the design.
Unrah is a demon who practices magic as a backup for his natural abilities. He usually appears in his human form. Even in that form, he can summon his wings at will. He only uses his full, demonic form when he's so stressed or emotional that he can't keep the illusion of humanity.
Issan Unrah is a name given to him by Sagitta. The two have quite a bit of *ahem* history.
Originally, Unrah had metal wings, but I felt that it didn't suit him as much as these do. He's one of my oldest characters and has gone through a lot of changes. I might draw a few of his old designs all together some time...
