Ichirou was the only waiter in Cafe Bonheur before Uru's arrival. He's always dozing off, and the only way to wake him up when he's fallen asleep is giving him food. He's repeating his third year in an advanced high school, allegedly because he fell asleep during too many of his classes the previous year.
He's often referred to as a "weirdo" and he never seems to interested in anything that happens around. However, he seems to have great insights on everything. He becomes very fond of Uru and states that it's boring when she's not around. He also enjoys teasing Shindou.
