Would anyone know the kanji here? I think it may be a clue as to what we can classify these girls as. I think they deserve to have their own tags given the amount of times they show up in hetza's work.

幼 means "young" and the young one is probably Waka.
美 means "beauty" and the elegant one could be called Mei, or Harumi, or a lot of other names.
晋 means "advance" (the shin from Shingeki no Kyojin) and the aggressive one's name might be pronounced Susumi.

Sweet! Thanks for that.

Do we have a name for the short one?

普 Not 晋, also the shin from Shingeki no Kyojin is 進
普 as in 普通, which means normal

Thanks for the correction

I wonder how I was that far off when it's written right there on the manga. Must have been going from memory or something.
