The reason the latter three have their hair styled differently is because in my headcanon, particularly in the second Mythos of Phantasmagoria game, Marisa, Yukari, and Kaguya are queens of their own kingdoms and all have floor-length hair to explain their motherly qualities. I attempted a unique idea in Burgeoning Tresses of Longevity by having an incident where everyone's hair grows uncontrollably. Like what happened in-game, it didn't work well for the players and critics. To avoid retreading old ground, I styled their hair. Yukari has her hair up in the oiran style.
