Months after the final stages of the Ultimate Tag Series, rumors begin to circulate about Phantom's Gate, a graveyard for Beys.
Hearing screams from a nearby mansion night after night, Bashara Suiro sneaks inside to test his courage. Waiting for him are two Bella and Bel Daizora, wielders of the Quad Bey Destruction Belfyre. As it turns out, this mansion is the rumored Phantom's Gate, and the screams Bashara hears are the cries of Bladers whose Beys have been destroyed. Bel and Bella issues a challenge to Bladers all over the world to come and battle them.
In response, Blading royalty appears in the form of Lui Shirosagi. Even as Raid Lúinor chases Belfyre down with its intense attacks, Belfyre shows off the awesome power of the Quad System, bursting its foe. In response to Bella's devastating battle, Blading Legends all over the world set their sights on this Dark Prince and Princess. And from the crowd, emerges a new Blader who might just topple the Dark Princess and Prince.
Having made an enemy of every Blader in the world, the curtain's about to rise on Bella and Bel's legend as the Dark Princess and the Dark Prince!
Legendary Blader Valt Aoi has been training the next generation of elite Bladers at Spain's BC Sol. One day, rookie Bladers Dante and Demi Koryu and Delta and Destiny Zakuro witness Valt unleashing his newly-evolved Gamma Bey, Sword Valtryek.
