I'd have to say I pick his human form. I despise him either way, but when he's in his human form, he has somewhat of a heart. Though, he's weak and helpless in his human form, he's much more kind than he is as a demon. As a half-demon he's a manipulative sociopath, as a human he's okay, and as a full-demon he's just a violent killing machine.

i think his full-demon form is a bit creepy .-.

I'm saying the same thing- I found his full-blood demon form to be...darker.
