Eight Unabara skateboards along a half-pipe in a basement with his bey, while his brother, Kite Unabara is in the same room, studying the mysterious Beyblade owned by Zyro Kurogane; Samurai Ifrit W145CF. Kite wishes to study this Bey to the fullest to find out what makes it so successful.
Zyro Kurogane, Shinobu Hiryūin, Maru, and Benkei Hanawa meet at a park where Benkei announces training for Zyro and Shinobu to complete.
The first part consists of Zyro and Shinobu running a multitude of laps to discover who is the fastest among them. They ready themselves and take off in a dash, with Maru hosting the laps. After 10 laps, the two are still up and raring to go, while by lap 20, they turn tired and by over 30 laps, Zyro and Shinobu give up as they cannot take the running much longer.
More exercises follow, and Zyro and Shinobu do various activities. One exercise is rock-climbing where once Zyro and Shinobu get to the top, they both fall down in pain and agony as yells follow from them both.
After the training, it ends, with Benkei rewarding Zyro and Shinobu with BBQ burgers for them all; due to a job well done. They eat their burgers in the greatest delight, knowing that this is what their training has paid off for.
Back at the basement, Kite Unabara finds out the secret of what makes Samurai Ifrit so powerful. After many instances of the word "perfect", Kite gives a grin as he now knows how to defeat the so-called unbeatable Ifrit and show Zyro Kurogane what occurs when one messes with them.
Zyro, Shinobu, Maru, and Benkei walk alongside a street at night, where Eight appears to them and hands Zyro a note. Stating to meet at the Beypark for a battle between Zyro and Eight's older sibling, Kite Unabara. Though quite suspicious of this, the gang decide to go ahead with it and travel to Beypark.
Zyro Kurogane takes one side of the Zero-G Stadium and Kite Unabara does the same. Kite also introduces his Beyblade, Guardian Leviathan 160SB.
They both yell "Let it Rip!" and start their Beybattle. The battle so far, seems average, with the Stadium mildly swaying. Zyro stays rest assured and confident while Kite only bears a grin as he announces to Zyro he knows what makes his Samurai Ifrit powerful and will launch his master-plan, as a cliffhanger follows.
