Kojima, Mizuiro

小島水色

He is a friend of Ichigo and the others. He has a boyish face and speaks gently. It seems to give Keigo the creeps at times when he speaks respectfully to him. Also, Mizuiro has a fondness for older women, a fact Ichigo revealed to Rukia at the beginning of the series.
Later in the series, along with Tatsuki and Keigo, he is fully endowed with spiritual awareness and is able to witness the departure of Ishida, Chad, and Ichigo to Hueco Mundo.
Although Mizuiro has no trouble attracting several girls at once (which makes Keigo extremely jealous), he seems to have suffered from lonely depression before meeting Ichigo and Keigo. He hardly ever sees his parents due to their busy schedules, which causes him to develop an inverted personality. Although Keigo was Mizuiro's first real friend, Keigo later admits that Ichigo was the first person Mizuiro ever really opened up to.
