Loud, energetic, and often abrasive and aggressive. Easily excitable and dangerous in a fight, her unpredictability leaves her often assigned to the B-team, much to her dismay. Sister of Romanorum. 

Reserved and deliberate, yet as ambitious as any. She likes to always think things through and make a plan over acting on impulse. Dangerous when she needs to be, but never the first to rush into a fight.
