Эпизод 4

Shion is officially named the Kiba heir and given the family heirloom, an ancient sword that supposedly glows when held by the true Kiba heir. Shortly after, he is challenged by a young boy named "Ace". Not only is Ace's corporation trying to take over the Kiba foundation, but he has also tricked Shion's uncle Utsugi into stealing the sword for him. With much at stake, Shion cardfights Ace, both using decks made out of cards pulled from random booster packs. When Shion sees the sword shining in Utsugi's hands, he loses both his fighting spirit and the battle. Ace later reveals that their fight was captured on video to smear Shion's credibility as Kiba heir, the glowing sword was a mere trick, and Utsugi was working with Ace all along. In the end, Ace's takeover of the Kiba company is successful, which forces Shion to start living by himself while his parents and Iwakura seek help elsewhere. Nonetheless, Shion vows to get revenge on Ace.
