So, final thoughts:
I was only really able to catch 3 of the 5, but I'll say what I know for now. I'm probably just gonna skip Momo, Kai seemed interesting though, I'll watch the VOD of her debut later.
ROCA: Really talented, really funny. Clearly a great asset. Excited to see her content and hear more of her covers because holy moly can she belt her heart out.
POKO: Lidl-brand Yuko, who's already walmart-brand Gura. Not gonna pay attention.
CONI: ...against my better judgement, I'm still gonna give her a chance. I saw the warosu post, and it seems to me her biggest sin was going insanely menhera against Lumi because of one of her mods being garbage. I do think she didn't need to go so far but menhera fluctuates, so I'll be cautiously optimistic. More than anything she's pretty funny so I'm willing to let bygones be bygones as long as it doesn't bleed into stream content.
