CardFight Vanguard is a Trading Card Game that takes place on a planet called "Cray," which resembles Earth, and involves players battling each other. After 3000 years, Planet Cray has transitioned into a new era, known as the Chakrabarthi Divine Era. In this era, all the clans in the game have been split into five powerful nations: Keter Sanctuary, Dragon Empire, Dark States, Brandt Gate, and Stoicheia.
