Kojima Mizuiro is a student at Karakura High School and a classmate of Kurosaki Ichigo. He was born on May 23 and lives in Karakura. Mizuiro looks younger than his age, which, combined with his pretty appearance, makes him popular among older women. He is smart, level-headed, and keeps his composure even in the most dangerous situations. Mizuiro is a close friend of Asano Keigo, whom he often teases, calling him "Asano-san" when he overreacts. Despite his outwardly friendly demeanor, Mizuiro is rather withdrawn and doesn't let people get close; the only one he truly opened up to was Ichigo. He is able to withstand the presence of strong spiritual entities and shows remarkable resourcefulness in critical circumstances. Years after the victory over Yhwach, Mizuiro continues to live in Karakura and maintains his friendship with the Kurosaki family.
