They were all pretty great. Kiara's was insane. I'm really glad that something like Hololive exists where much of the entertainment comes from the members pretty much being themselves through their characters. So much of each person is allowed to shine through.
Idk, for me it was Mio who literally sounded like Pekora. Mio didn't just do the well known Pekora phrases. Mio was literally talking casually like Pekora. She can stream on Pekora's channel and no one would notice, just don't try the laugh.
The craziest thing is Pekora's weird but cute voice is her real voice and he doesn't have to try to make it sound cute like other girls ( many). But because of that her singing not good like a lot of hololive member, it's just sounds like a kid
