Aki

亜希

Aki is Neon's youngest sister and a member of Uruha Oto (Sound).
Aki is a young woman who appears to be in her mid-teens, with short, pale blue hair and darker blue eyes. During her first appearance, she wore blue jeans, a sleeveless white outfit, and a blue breastplate over her chest. Her madogu is housed in a choker she wears around her neck.
When her madogu was activated, she removed her outfit, becoming topless while facing Domon from her illusions. She wore only a pair of white panties until she returned in her primary attire after Domon managed to break free from her illusions. She is not seen wearing a choker after Domon destroyed her madogu, along with her blue breastplate.
