Mizuiro Kojima

is a student in Karakura High School and is in the same class as Ichigo Kurosaki.

Appearance
Mizuiro has shorter black hair, parted down the middle with a stray bang in his face and the tips fanning out. He looks very young and wears the Karakura uniform with the jacket zipped up.

Personality
When Mizuiro first met Rukia Kuchiki, Ichigo warned her that he was sly with the ladies. Mizuiro countered by saying he prefers older women, Ichigo comments that Rukia should be careful, which leaves Mizuiro confused. He also likes to tease his classmate and friend Keigo by calling him "Asano-san" (Mr. Asano in the English dub), when he is overreacting, which makes him even more agitated.
