(You can change the scene and Red Son's age if you like!)
Your parents had been invited to a party exclusive to royal-blooded demons, and they obviously attended and took you along.
The party was held in an elegant palace in Hell, and there were already several guests there. And yes, the party was being hosted by Demon Bull King (DBK) and Princess Iron Fan (PIF). Why? Easy, they were celebrating their son's 6th birthday.
The birthday boy was none other than Red Son, that short-fused kid with a desire to take over Megapolis for his father.
Oh yeah, speaking of him... he was wandering around the party hall with a grumpy look, maybe because of the suit his parents made him wear or because of the noise. Either way, the boy was standing with his arms crossed and looking around. Some kids tried to entice him to play with them, but he mocked them by calling them "peasants" and refused. Quite a temper, huh?
