Miwa Mikadono

Miwa is the youngest of the Mikadono Sisters. She is a high school girl with a unique two-tone short cut, with the top of her head being blonde and the rest of her hair being green. Like her sisters, she also has golden eyes.

Miwa is a genius shogi player with an IQ exceeding 180, occasionally winning in shogi and chess competitions and leading her team to victory in international mathematics competitions as the youngest female representative. However, her outstanding genius often isolates her from others, as she lacks interest in mundane conversations and people tend to keep their distance from her. Moreover, her genius is predominantly focused on her intellect, so her physical abilities are mediocre compared to Yuu's.
