Ghost Disguise / The Masked Ghost.After attending a party and getting reacquainted with an old friend, Yuya Karasumori, Shion overhears rumors about the Masked Ghost, a mysterious fighter who has been challenging other players and taking their avatar cards. One day, after he and Yuya spar in a fencing match, Shion is told that he will get special training from a professional fencing representative in a few days. Later, Shion receives a tip from Ryota, the boy who he befriended at the Vanguard Quiz Competition, that the Masked Ghost has been spotted. Shion tries to confront the Ghost, but he escapes. Some time later, after hearing more info about the Ghost from Ryota, Shion awaits training from the fencing representative. Just as Shion realizes the true identity of the Ghost, he receives a message that tells him that Ryota is fighting the Ghost at a warehouse and rushes over there. He arrives soon after Ryota loses to the Ghost and has his avatar card taken. Shion challenges the Ghost, who enforces a unique condition to their cardfight; Shion must play with 12 triggers taken out of his deck, but if Shion wins, then the Ghost will return all of the stolen cards. Shortly into the battle, Shion exposes the Masked Ghost's real identity: Yuya, who reveals his true motives to why he has been doing this. Nonetheless, despite the large handicap, Shion defeats Yuya, who runs away after leaving all of the stolen cards. In the end, Shion loses his chance to receive professional fencing training, but he has no regrets and believes he will get another chance.
