Miwa Mikadono

Miwa Mikadono is the youngest of the Mikadono sisters, a 17-year-old high school student with a two-tone blonde-and-green haircut and golden eyes. A shogi prodigy with an IQ above 180, she has also succeeded in chess and international mathematics competitions.

Her extraordinary intellect can leave her isolated, since she has little interest in ordinary conversation and others often keep their distance. Her physical abilities are much more ordinary than her academic gifts.
