Her name is Cobaka, Marcus's ex-beast girlfriend. That Beast that got away, "Noooooo!" HAHA!! And to stop Marcus from mind controlling her, she has the pseudo "Aluminum Foil" Hat contraption to stop him from controlling her mind. She is the Lazarius to Guild, but Beast to Marcus. She ends up being Mei Fengs friend and learns the ways of fist fighting, thus the brass knuckles. Not that Mei Feng's squad needs anymore help with scrap moving and MI advantages. But that is my story and I am sticking with it.
