Everyone is talking about the mysterious Gear Chronicle deck, possessed by only one person... who is currently suffering from a major toothache, but rather than going to the dentist, Chrono heads to Card Capital to fight a classmate, a beginner who`s been coached by Tokoha, the girl destined to become Chrono`s rival!

Shion wants revenge after losing to Chrono, but he`ll get his chance in an unexpected way: the Vanguard Quiz Tournament, an event that pits Vanguard Cardfighters against each other in games that test their knowledge, ingenuity, and fortitude!
