>>54789546left is hyper-idol. watches idol anime, plays trash idol gacha, career in singing idol songs, and obviously music is part of her character theme. think suisei where she's intensely focused on it but not much else.
purple loli is moderately idol. she has aspirations, decent voice, seems willing to tow the line, but not more.
twins are less singing/dancing idol and more highly corporate variety show idol. it's not often these two halves are unlinked, as generally you unified enthusiasm. when seen from above, they'd be considered somewhere between the former two in terms of intensity, so more than moderate but not extreme.
