i wouldn't change anything about the actual subunits, but thought it would be interesting to imagine what different subunits could be like in a 3-3-3-3 format.
shizuku/kanata/mia: elegant unit, fairytale themed
lanzhu/ai/rina: genki unit, bubblegum pop and chiptune, stuff with a cutesy vocaloid type song vibe
kasumi/setsuna/karin: cool unit, i guess they'd be like bibi 2.0, maybe with some rock thrown in
ayumu/shioriko/emma: pure unit, haven't really thought hard about what their sound would be like
