Chazz's brothers, Slade and Jagger, want to take over Duel Academy. The Academy's current owner, Seto Kaiba, has proposed a deal - one of the students would duel against Slade, and if Slade won he and Jagger would be allowed to buy out the Academy. The chosen student is Chazz, but there is one more rule: he must use monsters with less than 500 attack points. Chazz builds a new deck of seemingly weak monsters by using cards that others have thrown away, including the Ojama Trio (he finds Ojama Yellow's brothers, Ojama Green and Ojama Black, who also can talk to Chazz). He faces his brother and wins, not only saving the school, but proving that the strength of a duelist does not come solely from his cards, but also from his heart.
