>>2457567A couple other girls with either classical or modern type costumes that I haven't thought through much. One has lightning powers and loves to show them off by blasting entire monster armies with gigantic storms of lightning bolts and especially by using her lightning sword and super speed for dashing slash attacks. The other has wind powers and usually stays calmer and acts more reserved, preferring to support the others in combat by blowing monsters around and keeping them off balance. Unfortunately, having wind blowing around everywhere in a fight makes it almost impossible to control a miniskirt, and completely impossible to control light flowing robes. She's always apologetic and sympathetic for the inevitable embarrassment, but secretly enjoys watching it, especially with newer and more easily embarrassed girls.
A shy and timid girl with a "modern-type" costume of overlapping multicolored heart shapes that's not nearly as tight or as revealing as some of the others, but only at first. Her powers are pure support, directly amplifying the other girls' emotions and therefore their powers. But whenever she uses them she loses some of the hearts on her costume (each color corresponding to a different emotion, either disappearing or just turning transparent, possibly depending on how much power she uses, and possibly from a different part of the costume every time so that there's no way to predict exactly what's going to be exposed). At first she can hardly stand to be seen like that at all and freezes in panic at any exposure, but after spending time with the other girls and witnessing their embarrassment and the way they all keep fighting anyway, she starts to push through her own embarrassment.
Incidentally, instead of the "constant baseline" idea from >>
>>3999709 maybe continuously overusing extreme emotion also affects the monsters, gradually increasing their powers and forcing the girls to use more and more amplification or intimacy just to keep up.
