Kai is torn between escaping the Abbey, now known as the Biovolt Corporation (with Biovolt being an acronym for Beybladers Intent On Victory Over Lawless Tyranny), or exploring it further in an attempt to unlock forgotten memories from his childhood. The Bladebreakers attempt to enter the abbey to track down their missing teammate, but are denied access by two of its bladers, Ian and Yuri Ivanov, under orders to stall them. After fighting his way through the tunnels, Kai discovers the existence of Black Dranzer, the world's most powerful Beyblade. Boris offers it to him - but only if Kai quits the Bladebreakers forever and rejoins the Biovolt Corporation. Flooded with memories of using Black Dranzer as a child, and the lure of its dark, corrupting power leads Kai to accept Black Dranzer and rejoin Biovolt. Yuri and Ian are then ordered to tell the Bladebreakers that Kai was caught sneaking around the facility and got a fever for staying too long out in the cold. (Source: Wikipedia)
