I don't prefer this weird gimmick she's been doing for literal months where she's all like "Ooh, Haachama and Akai Haato are different people and they have different personalities and one of them is like killing the other one or something?" I don't watch VTubers for some dumb storyline where they're playing a character. I watch them for their streams where they're playing a game and talking to the chat and it's literally just them talking and reacting to the game normally.
Same reason I hate this Pekora prisoner nonsense, but at least she knows when it's dragged on too long and has mostly gone back to normal streams. Haachama meanwhile seems to have zero concept of when to end a joke and so we're still dealing with this split personality bullshit.
