Bladebreakers, the current Beyblade world champions, have split up. Max is back to the United States and Rei to China; Kai's whereabouts are unknown; and Takao spends his days peacefully in Japan, dealing with every day issues at school and having some arguments with his classmate Hiromi Tachibana (Hilary in the English dub and the versions based on it). One day, a local supermarket promotes a minor beyblade championship whose winner will have the chance to challenge Takao. The champion, a mysterious boy who goes by the name of Mister X, shows an overwhelming difference in strength in the battle and it ends in his easy victory, leaving Takao speechless before a shocked audience.
