Killing, rape, threats. That's all he does. He's too dangerous to society. That's the reason he's never allowed out by his father and those few times he has, most of his face was covered by a mask. No one knows how he looks or his name, but it's still terrifying knowing that would be the future king of one of the big races, the demons. All the demons is bad in general, but this first born prince that scare even the most powerful beings is topping it off. No one really knows him though, do they? Well, to make sure the peace continues between the two races, but mostly for good looks in society as the pure and kind hearted people they seem to be, the Supreme deity offered that the Demon King and his sons would visit and stay for the two heirs to bond, or rather, learn to tolerate each other. That's when all started. The supposed cold hearted, ruthless man started to open up and decided to disobey his father in the worst way possible. He decided to show his face.
