Miki (魅希) is the middle sister of Aki and Neon and a member of Uruha Oto (Sound) .
Appearance[]
Miki is a young woman who appears to be in her mid teens. She has reddish-pink hair that fall to the middle of her back, and seems to curls upwards in a few places. She also has two moles under her right eye. She wears a multi colored one piece skin tight outfit. Her left sleeve is short and black, leaving the right one bare.
Personality[]
Unlike the more condescending Aki or more forceful Neon, Miki takes a more middle ground position as the middle sister. She seems to be the most laid back of the three. She is also quite flirtatious at times, and has even wanted to kiss Tokiya in the middle of a battle. Like Aki, she is fiercely loyal to Neon, as shown when she wanted to die alongside her sister.

Abilities[]

Miki using Idaten in battle.
In contrast to Aki and Neon's madōgu, Miki's madōgus are generally utilized for support in battle. In addition to her two madōgu Miki also has a set of nail-like claws to attack opponents close-up.

Idaten (韋駄天, Great Runner): This madōgu when worn on the feet allows the user to run at great speeds, even allowing Miki to intercept Neon's sound based attacks. It is her main madōgu.
Yamabiko (矢魔彦, Echo): Miki's second madōgu is a circular disk that she wears on her forearm which allows Miki to reflect attacks that hit it, most notably sound based attacks.
Etymology[]
- The name Miki means "fascination, charm, bewitch" (魅) (mi) and "hope" (希) (ki).
