We never made clear who got what.
I think from my previous suggestions that it'd be a good idea to distribute them as such:
Mao: Moon Atomizer
Amaterasu: Moon Atomizer, Star Atomizer
Kath: Sol Atomizer
Reasoning: Although it might be a good idea for Mao to have both Moon Atomizers, the party splits often enough that Amaterasu should have one too, being the next tankiest person in the group. It also helps to cover more distance.
Star Atomizer is better in the hands of Amaterasu since she is a such a damage magnet/sponge. Good movement to activate it anywhere too and Mao is less likely to need the healing anyway.
Monofluids all go to Hugo or Baha also gets one. Mostly to help them dish damage and because recovering spells is better than recovering maneuvers.
Sol atomizer to Kath since we always want her on the move. Because of her utility set, we really want her to always be able to do stuff each round.
