Eido Kubozuka

Eido Kubozuka is an air-headed partner of Hyde who loves to skateboard and eat yellowtail hamburgers. He's crazy about girls, and he loves Megumi and her music.

Hyde describes Eido as the opposite of Kiyomaro; he doesn't go to school, have any friends, and is a poser. He also isn't very smart, as when he left a note for Kiyo to come save his friends, he didn't mention where to go.

Hyde and Eido were last seen at a Megumi Ooumi concert during her first appearance on the series and never again.
