Bashara Suiro and his sister, Hanna, venture into a haunted house. They watch as others exit the home screaming, but that doesn't stop Hanna's curiosity. Once inside, they experience many scary events, which eventually leads them to a room with a bey stadium. A small boy dressed in bat apparel named Bel Daizora appears. He calls himself "The King of Hell" and asks that people address him as the Dark Prince. His Beyblade is Destruction Belfyre Nexus Venture-2. It is smaller than a usual bey. Bashara, being a blader, accepts the challenge to battle. His Bey is Demise Spellscraper Metal Fusion 2B. At BC Sol, Valt Aoi is battling with other members when they notice something taking place on Beytube. Elsewhere, Lui Shirosagi is watching as well. After launching, Belfyre takes numerous hits, but because of its low center of gravity, it doesn't slow down. When Spellscraper begins to lose stamina, Bel attacks with Destruction Wrecker to burst his opponent. Free De La Hoya wonders if this is a new generation of Beys while Lui is intrigued in the new blader.

Reeling from his loss to Bel, Bashara is determined to get stronger and battle the Dark Prince one more time. But Ranzo Kiyama, an energetic Blader from Brazil, arrives on the scene with a similar goal in mind. Despite their differences, Bashara and Ranzo team up and make their way to Phantom's Gate to challenge the Dark Prince.

After Ranzo takes a surprise point from Bel, it's time for the Dark Prince to get serious. Determined to prove he can win, Bel challenges Ranzo not just to a battle, but to anything — eating, dishwashing, whatever they're in the middle of! Ranzo swore he won't go home until he defeates Bel, and at this rate, he might even leave.
