Calli is just absolutely average. She sucks at rapping, she never used the sounds of words properly to deliver hard hitting rhymes and never used change of pace and never used anything meaningful. When she posted on her roommate it became obvious how average she is, because while it was better than her hololive stuff, it exposed how absolutely middling she is even with no restrictions. Just listening to her butcher Eminem's deliveries is maddening. He doesn't pronounce words the way he does for fun, when he says "sinna" instead of "sinner" then delivers a like about quarterbacks referring to a center, he did that to make the like work but Calli over here pronounces everything with 0 intonation and ruins the line
