Wait, there's a Japanese idol group called Iz*One, but I don't recall those names. Maybe it's a different group? Alternatively, maybe they are from NiziU or another J-pop group? I'm a bit fuzzy on the current J-pop group members. Let me confirm. Karina is definitely from aespa. Misaki and Shiratori—I'm not sure. Maybe they are part of a different idol group. Alternatively, the user might be referring to a specific unit or a fan-made group. Alternatively, maybe these are characters from a drama or a game. The names are pretty common in Japanese pop culture. Hmm.
