Dio Hamada is the complete opposite of Shiro and the oldest child. He's all about soccer and Alice (The oldest sister of the Stones). His hair is slightly longer than Shiro's, due to people saying that they look alike, so they both agreed that they should try to act different from one another. Dio is actually just as smart as Shiro, but he rather not show it because then all he and Alice will talk about is boring stuff. He wears anything that's light and comfortable, that includes formal parties, but he's forced to wear something formal all the time. (Btw, his mom thinks he's an idiot also. That's why she choose Shiro to be the heir.)
