Summary
A new game shop has opened in town and it may put Grandfather Mutou out of business. Even worse, it seems its owners want to put Yugi and his grandfather completely out of the picture. Then, the owner's son, Ryuji Otagi, challenges Yugi to a dragons and monsters game he must play without Yu-gi-oh's help.
