Chrono takes on a quest from someone who wants to fight and test out a new deck. When Chrono goes to the specified meeting place, Vanguard Colosseum, he is greeted by a young man, Kouji Ibuki. He brings Chrono into a special room that is equipped with a Grand Image Reality System (GIRS), which is able to bring Vanguard fights to life through advanced holographic images. Chrono and Kouji engage in a cardfight with Chrono gaining the upper hand early. But Kouji soon reveals his sinister persona by toying with Chrono while exposing his weaknesses, comparing him to a child. Desperate to turn the fight around, Chrono attempts to stride Interdimensional Dragon, Mystery-flare Dragon. At the same time, Mystery-flare Dragon begins to appear in the real world, with only children being able to see it. However, the dragon disappears before it could fully emerge. Meanwhile, the GIRS shuts down, thus stopping Chrono and Kouji's fight. Kouji leaves without ever revealing his name to Chrono, who is left feeling completely frustrated.
