Іура Мотоко

She is Shuu Iura's younger sister.

Self-described as an untalkative, gloomy type, Motoko is the opposite of Shuu. She tends to keep to herself and has a hard time making friends. However, unlike Shuu, this personality also carries over to her school life, though she is much more forceful and violent towards her brother than others. She is also pretty smart but lacks the confidence to use it too well.
