According to the commentary, the artist drew this after seeing something similar done with the female characters of Dungeon Meshi, with all of the girls here (all of the commanders + Übermensch) having their hairstyle the same as Miho.
The one who looks the most off to me, surprisingly, is Maho. The other's hairstyles are so different from their norm (minus Katyusha, but she pretty much looks the same), that it just falls under the mental category of alternate hairstyle, but Maho's hairstyle was already pretty similar to Miho's, that the tiny change (the inward curled sidelocks in front of the mid-length sidelocks) completely throws me off.
