Ep. 48: Rise of the Sacred Beasts (Part 1)

The seven keys had finally unlocked the Sacred Beast cards from underground. Kagemaru, leader of the Shadow Riders and superintendent of Duel Academy, appeared to steal the cards. Since the beast cards feed off duel energy, he built the school and hid the cards underneath it so that they would get stronger. He duels Jaden using two of the beasts, Uria and Hamon, and then uses their power to make himself younger. (Source: Wikipedia)
