Aka is a hard headed, stubborn, sharp-tounged character. She has often been mistaken for a male versus the average female, due to her body type and her hair style. She is a very cold character, relatively, but is only trusting towards Maiku and the few she views as worthy to be her friend. She's very rough and tough, and fits the definition of a tomboy perfectly. Her quirk is Blood Manipulation - she can create  a weapon from her own blood. Aka has a deeper female voice that makes her sound more like a feminine guy.
