First Match! Miyaji Academy vs. Hitsue High School

Miyaji Academy's unofficial Cardfight Club is set up to have an intramural match against Hitsue High School's Vanguard Club, in which Kai, Miwa, Morikawa, and Izaki are members. The two teams play in a best-of-5 match, and opponents are randomly selected. Under the conditions that the Miyaji Academy student council president created, if the Cardfight Club loses this match, then it will be dissolved. In the first game, Naoki fights Kai, with both using Eradicator-themed Narukami decks. Naoki combines both the Break Ride of Eradicator, Vowing Sword Dragon and the Limit Break of Eradicator, Gauntlet Buster Dragon to retire Kai's units and gain more critical value and power, but Kai manages to survive the assault. Then, Kai uses a similar devastating combo with Vowing Sword and Eradicator, Dragonic Descendant. Although Naoki blocks his first attempt, Kai activates Descendant's Limit Break to have it stand up, gain another critical, and attack again.
