Lemme just throw Hamuko out here. Combat-skill wise, I think she would still retain most of her naginata wielding or strategy skills, since that's not TECHNICALLY part of her entry fee but rather the whole Dark Hour business and I assume she would have that outside of the game (since she's in a couple of clubs and she wields the naginata like a natural so--)

UH I HAVEN'T TOSSED HER IN ANY FIGHTS YET SO I GUESS SHE ONLY REALLY HAS ICHIMOJI? I assume she'd be hella flexible once she gets into the business of things!
