Chancellor Sheppard brings together Jaden, Chazz, Bastion, Zane, Alexis, Banner and Crowler to tell them about three legendary and powerful Sacred Beast cards hidden under Duel Academy. He reveals that the Seven Shadow Riders are planning to unseal the cards and harness their power. He gives each one of them one of the seven "Spirit Keys", which have the power to unlock the seal. As the Shadow Riders descend upon Duel Academy, they each must duel to keep control of the keys and prevent the release of the Sacred Beast Cards.
