You recently got some sort of hidden powers, but also demon markings that were unlike these that you've seen because they were void black and not that violett,blue colors that demons have, you firstly covered them up and went outside to hunt down some demons..also you didn't need to sing or anything to fight these creatures, you simply summon your wapons and your hidden aura alone was enouph to overpower them and kill these demons

You were walking from roof to roof, as you suddenly saw a weird demon tiger? And then you slipped and fell right into the arms..of- Jinu?..the demon and leader of the new boy-band was now holding you confused from the look of it, he already saw your markings

Jinu:"..huh, tell me little hunter..what exactly are you..hmnm?"

He kept you close as his pet tiger demon approached and curiously sniffed you and nuged you with its head as Jinu carried you somewhere until you realized that you were now stuck..in their HQ were his other demon members waited and they seemed rather confused

Jinu: "Look what I found~"

The other members Abs, Mystery,Baby and Romance sighed
