The Return of Kai (トレビア〜ン!, Tres Bien!) is the forty-sixth episode of Beyblade: G-Revolution.
Kai pays Tala a visit at the hospital and collects the new Dranzer Tyson left before the start of the tournament.
Tyson and the rest of the team are practicing furiously to guarantee a check in the win column for tomorrow's big match. Tyson thinks no one on the team has the same skill with the Hard Metal Beyblade and he refuses to choose any of his teammates to Blade in the penultimate round of the tournament, insisting instead to blade both rounds himself.
Meanwhile, Kai tries to practice with his new Dranzer, but is unable to control it. Eventually Drazner hits some windows, which sends glass pieces flying towards Kai. F-Dynasty's coach Romero, who was fishing nearby, finds Kai and knocks Dranzer out with his beyblade. He then offers himself to help Kai gain control of Dranzer and challenges him into a match. Kai eventually uses his will to defeat Brooklyn and Tyson to regain control of Dranzer and win the battle.
He then meets Tyson and the others by the river where they were practicing.

- In the original, when visiting the hospital, Kai simply says "Yuri..." and spots Dranzer MS on his bed.
- The dialog was altered in the English dub. Instead, an unseen woman tells Kai that visiting hours are almost over, but Kai (shown from behind) simply answers "I'm not leaving".
- Before his mouth is shown, he also says "Tala" (Yuri's name in the English dub) and asks "Can you hear me?" (in the original, he says his former teammate's name).
- For some reason, the glass pieces that are sent flying towards Kai after Dranzer hits the window were cut from the English dub.
- As of this episode, the G Revolutions are officially reunited.
