This is the Evil side. Not exactly THAT evil but they're just the opposite of Mune's group XD

That boy is Mura, a rather stuborn, stuck up, naughty boy and his.....Mr. I-don't-have-his-name-yet. These two pairs love to fight a lot every time they meet (usually with Mune and Mura just watching their partners beat each other up from outside the arena *shrug*) but who knows how their story goes? >;3

Mura and Mune are cousins by the way XD
