Bell has found mention of a mythical Blader called the Devil Blade in an ancient book. He decides to go look for it, and Ranzo and Basara join him. They arrive at an island on a helicopter, flown by Gramps of course. The gang climbs up a mountain and does some platforming challenges before arriving at a large room. In the middle of the room is a large Bey Stadium, like 10x bigger than normal. Devil is lodged in a wall Galaxy Pegasus style. Bell removes it and the gang looks at it. But suddenly, the statue next to them awakens. It's a Gargoyle with a giant launches. It launches the big bey into the large stadium the boys are standing in (It's from an unknown system.) The bey circles around the rim of the stadium. Bell replaces Dynamite with Devil, making Devil Belial. Devil attacks the bey and it knocks it away. Bell goes full power to chatter the bey. The Gargoyle breaks as well. Everyone's happy and Bell is victorious, as he's found Devil.
We're at a school for some reason. And then, we see Bell casually walking through the hallways and he breaks into a classroom. It's Basara's class, and he's glad to see him. He sees the desks are lazily strewn about so he orders his classmates to put them together, and they do reluctantly. They also clean off the desks. Now Bell has his red carpet. He walks across the Desks, straight to Basara. He's just sitting in his seat and is confused. He tells him that the Demon King himself came to see him. He's surprised that it's not enough and erases all of the writing on the Black Board. Another kid reluctantly cleans off the erasers for him.
He goes to Basara angrily, expecting him to be happy that the Demon King came to see him. Basara is scared at his appearance. Basara pretends to his friends that he doesn't know him, and then goes to talk to Bell. He says that he heard Basara made a new Dynamite System bey from his Gramps, so he came to battle it of course. Basara yells at him, saying of course he's gonna battle. That's the whole reason he made a new Bey. However, he's confused due to the lack of a stadium, but Bell's got that covered. A giant hot air balloon comes with hands that's carrying a Bey Stadium. It drops it righto outside the window of Basara's class so he can see it. Bell now invites him to play, but the teacher doesn't allow it. Beyblade is banned. Bell asks why, and the teacher simply says because it's banned. Bell gets made and cries, but tries to cover it up.
Bell quickly whips back into shape and then counters. Basketball and Soccer are not necessary for school, yet they are allowed. Beyblade is also a sport, so why is it prohibited? The classmates are scared, but agree. Bell says with Beyblade, you train your body, build friendships, and learn to put effort in. He gets the class to rally in support of Beys, but Basara tries tells him to shut up. Bell looks at the teacher in approval, but he simply says bad things are bad. Basara says he's just a teacher. Bell yells at him to be quiet since he's not talking to him, but Basara continues with the fact that they would have to go to the principal to make an actual change. Bell now decides to go to the principal, and gets everyone to follow him.
At the principal's office everyone is decked out in Bey gear and holding signs, with Basara reluctantly holding one. Bell asks but the principal says no. Bell says that this is a good school, however if he broadcasts a battle to his thousands of followers, the school will be more recognized. The principal says that they can battle just for today and Basara is surprised that they easily won him over. However even if it's just for a day, Bell is proud he's made Beyblade to play possible at school. Basara is amazed that Bell was able to be a hero in the blink of an eye...but that's precisely why he needs to beat him.
We cut to he gym where the stadium is. Bell holds out his new bey: Roar Bahamut. Hannah cheers for him, as the battle starts. Basara also has a Dynamite launcher now, and does a classic Shu Launch. F Gear Belial attacks but the perfect circle repels him. Basara yells out that whenever the lock progresses, the 4 blade defense turns into an 8 blade defense. New bladers appear and Belial isn't making a scratch. Bell keeps attacking, and Bahamut is starting to wobble. Basara is mad. He's yells that he's trained every day and watched every battle just to defeat Bell, and he can now do that with his Bahamut. Belial loses all it's stamina, meaning Basara has won the first round.
Hannah and her friends are happy, and Basara lets out a scream of victory. However, Bell is ready to up the skill level. Basara is scared, and he now has to bring more moves. to the table. Everyone comes to the stadium seriously, but Bell fakes out with a light launch. Basara is surprised, and Belial goes to Bahamut who is in the circle. Basara thinks that he's fallen into Bell's trap. His serious expression made him think he was going for a powerful launch. Bell smiles maniacally and Basara tenses up as Belial attacks. It hits the non Blade parts of Bahamut. It quickly gains spin, and Bell bursts Basara. With a 2-1 score, Bell wins. Basara collapses too the floor, and cries. All of his work was for nothing. Bell approaches Basara with a smile, and Basara stares back angrily.
