Dear Anon Cat, let me introduce you to Sin's brother. I'm taking "opposite of Sin" as "Opposing force" that can manage him. His name is Efret and he is a good boy. Not that he isn't a lewd boy himself, but a good boy. Efret's a war demon, and related to him through their father (assuming someone is going to ask). He's super super strong, and can actually deal with Sin when he needs to be handled. Efret also enjoy being nice to people. . . and being a decent... demon. As much of a good boy someone who can destroy cities can be. AH, its called self restraint. he has that. there it is. SO GIVE EFRET HUGS INSTEAD! XP

I should draw him more often, because Efret is so nice a fellow. I'm sure [Elflord] would love that, too.
