Miki

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 left one bare.

Unlike the more concescending 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.
