おとぎの国のレオン

As Yugi and his friends enter the restaurant, they find Vivian and Yugi's grandpa. Solomon explains how Vivian helped cure his back pain, but then Vivian undoes what she did earlier, bringing his back pain back. She challenges Yugi to a duel for his grandpa and Yugi accepts. Yugi duels Vivian and wins without much of a struggle. Back at the main duel, Leon and Rebecca continue. Rebecca does manage to get the upper hand on Leon by summoning her Diamond Head Dragon. As Yugi and the others finally arrive at her duel, Leon summons his Thorn Princess card to control Rebecca's dragon and attack her life points directly with it, bringing them down to 0. Though Rebecca loses, she congratulates Leon and wishes him luck in the finals.
