She is a young woman who appears to be in her mid teens with short, pale blue hair with darker blue eyes. In her first appearance, she wore blue jeans along with a sleeveless white outfit along with a blue breastplate over her chest. Her madogu is contained in a choker she wears around her neck.
When her madogu was activated as she removes her outfit to topless while facing Domon from her illusions, she only wears a pair of white panties until she returns wearing her primary attire when Domon manage to broke free from her illusions. She is not seen wearing a choker after her madogu was destroyed by Domon.
Aki is not above using her femininity to give her a win in battle, as shown when she made Domon believe she was stripping in front of him. However when it turned out that Domon's mental strength was far more than she first believed, she was quickly defeated. While initially seeming quite as cruel as any other Uruha member, when Neon threatened to kill herself to destroy Recca and Tokiya, she begged along with Miki to allow them to die with her, showing a strong bond of sisterhood.
