I gotta be honest lol, he isn't very good. If a 15 year old who'd never rapped before posted his bars up on here I wouldn't be particularly impressed tbh.
Hardest Asian MC I've heard is probably Mic Righteous. Riz was semi good as well but kinda cringe. Lowkey probably the most famous/successful but I can't stand him tbh.
Black The Ripper is half Asian also btw -
