Hyde (ハイド, Haido) and Eido (窪塚泳太, Kubozuka Eita) are the very first mamodo team that Zatch and Kiyo encounter in the anime, that had to leave the battle when Kiyo cast Zaker for the first time. Their powers are related to wind. Hyde is a serious mamodo who wants to become king of the mamodo world. Hyde finds Eido being picked on by bullies and offers him his powers to be strong. Eido is an air-headed partner of Hyde who loves to skateboard, eat yellowtail hamburgers, he's crazy with girls, and he loves Megumi and her music. Hyde describes him as the opposite of Kiyo; 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.
