A member of Hololive Generation 0. One of Hololive's top divas. However, she is incredibly cute when playing with stuffed animals and the like. She has a somewhat low, androgynous voice. Characterized by long blue hair and blue eyes. She wears a dress shirt with the top button undone and tight slacks. She likes yakiniku, fish eyeballs, cod milt (she's happy if it's in a hot pot), mentaiko, and C.C. Lemon (drink), but hates vegetables. However, potatoes, sweet potatoes, and thoroughly boiled onions are exceptions. She gets furious if you tease her about being flat-chested, so it's recommended not to do that. Well, she's kind enough to forgive you eventually. Age: 25. First person: I (polite/feminine) / Sui-chan (when joking around).

Suisei's older sister. A great beauty. She is very good at cooking, but since she basically just lounges around, Suisei sometimes calls her the "incarnation of sloth." For example, if Suisei asks, "I want to leave at 11 tomorrow, can you make food and wake me up?", she'll say okay, but will be sleeping soundly the next morning. Characterized by long pink hair. She wears a dress shirt with the top button undone and a red ribbon, with a navy cardigan over it. On the bottom, she wears slightly baggy gray pants. Compared to Suisei, her chest is bi... (Yes, it's big). Age: 27. First person: I (polite/feminine) / Onee-chan (when joking around).
