Judai's rival, Jun is always wanting to defeat Judai. He despises Judai and wants to take the place as "King Of Games." His family is very rich and he was able to win several championship matches before he went to Duel Academy.
Like Judai, he can see the duel monster spirits. In the anime, his Duel Monster spirits are the Ojama Trio (Ojama Black, Ojama Yellow and Ojama Green) while in the manga his duel monster spirit is Light and Darkness dragon.
