As the championship season is taking place, the “Bladebreakers” led by Kai is doing quite well and is a candidate for the championship. However, when they reached the knockout stage, a mysterious group called Saint Shields defeated most of the members, and only Kai could go on. They claim that Kai’s members are bad guys and that the sacred power of Bit-Beasts should not fall into their hands. As a result, Team Psykick tried to take Bit-Beasts from the Bladebreakers, by tricking them to a deserted island and using strength to force them. Fortunately, they were rescued by Mr. Dickenson in a critical time. But the question arises, who are their attackers, and what is their ultimate goal?
