Since Atlas is here publicly, it's time I rank her as well.
I'm putting her in B. Her dedication is amazing and I hope the marriage feature to come will make other characters inch closer to it! What holds her back is her outfit - the spacey Zero Suit Samus type stuff has never been able to reach much of a sweet spot for me personally, but I still think it's attractive and practical.
Also, this update has caused me to realized just how much of a mother Dusk Lamia has become over me. Not seeing her on the lobby by default was a very CURSED experience! >_<
