7x7 - Beyblade

Eight Unabara skateboards along a half-pipe in a basement. While his brother, Kite Unabara is in the same room, on a computer and studying the mysterious Beyblade owned by advanced Blader, Zero Kurogane: Samurai Ifraid. Kite wishes to study this Bey to the fullest to find out what makes it so successful. Zero Kurogane, Shinobu Hiryūin, Mal, and Benkei Hanawa meet at a park where Benkei announces training for Zero and Shinobu to compete it. They all cheer and get ready for the epic training to build up. The first part consists of Zero 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 Mal 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, Zero and Shinobu give up as they cannot take the running any much longer. More exercises follow, with Zero and Shinobu doing various activities.
