Looool. Well all justification I give from now on you'll refute, so there's no point me trying.
But yeah it is Demon, everyone has muscle on their stomach, otherwise you wouldn't be able to move it. It's not defined as a six pack, I never said it was, but that is muscle, the same muscle everyone has, it's just that I'm really thin around the hips, (I have like girl hips, and an hourglass figure, which really isn't funny cause guys aren't supposed to be like that. >.>) so it shows like that.
