MHA x My OC

Heya crazies, Crazy-dude here! Today we have another classic with MHA, I'm sorry... (I'm not) But we have MHA x My OC!?!?!?! So basically I'm just going to give you all the information sbout my character: This is Yamuyu, Yamuyu Haiko, Yamuyu has a strict past as he was abandoned by his parents and lived on the streets, causing his quirk to adapt and.... MUTATE! (Yes, quirks do that in this AU but only once in every 1,000 years to one person) This results in his quirk being extremely strong, it is called "Realm's Choice" it is where YOU CAN LITERALLY ASK GOD AND THE DEVIL FOR HELP AND CAUSE YOUR QUIRK TO SHIFT TO WHATEVER YOU WANT IF THEY SAY YES!! (Which is like a one in bajillion chance sence well... Devil, y'know..) Okay, back to appearance, he looks cold, rude, and soemtimes emotionless but he's actually very kind and nice once you get to know him, hes just a bit.... Introverted..He has black short messy hair with a white streak, he usually wears some kind of jeans and a sweatshirt, and the last bit of information.... He's in the school band, hes the lead singer...(Yes, he sings...) This... Was a long one, please enjoy it, I actually tried this time!
