Katsuo can team up with Regan and dual-wield. And when the going gets rough, Regan can resume human form and, I dunno, pick up another weapon? Bwahahahahahahahaha


Edit: Oh, is that a thing? Family can wield each other? Well, she can just keep normal weapons with her, then.

I should really just READ Soul Eater.

I'm fairly sure it is also briefly mentioned in the anime
Reason why Liz and Patty can use each other, but you don't see any other weapon use another weapon
