Zero and Co. have just met the true identity of the "sea monster," Gen Kinokura. Upon their unusual encounter, the gang discuss what they should do, now that they've met him. Gen stops them there and tells them his back story. The reason why Gen poses as a sea monster, is because he cares deeply for beaches. However, beaches have become infested and inhabitable because of the trash and litter the people recklessly put everyday. Gen only cares for the beach, and he'll never stop as the monster unless people care for their beach. Zero thinks he should Beybattle Gen to stop his terrible goals, yet Kite believes he himself should challenge Gen. Gen agrees to the challenge and the gang move to a water-esque BeyStadium to do battle. The competitors "Go Shoot!" and the battle begins. Mal studies Gen's Beyblade, known as Pirates Killerken and discovers something that will make the battle hard for Kite. Killerken uses the A230 Spin Track, which blocks low-attacks such as from Kite's Guardian Revizer. A230 not only gives Gen the advantage, but stalls the battle completely. The Beybattle, originally a fight becomes a sleep-out where Kite and Gen wait impatiently for their opponent's Beyblade to stop its spin. Outside water even retreats to the BeyStadium and causes no effect. This causes everyone else besides Zero to enjoy some summer fun rather than the boring battle. Zero then yells out randomly and commands the battle to end, with no winner due to no result, at anytime soon. Zero tells Gen that he will fight him next, this time with a result. Zero and Gen ready their Beys and launch into the Stadium. As hard as the battle was on Kite and Revizer, it's the same with Zero and Ifraid. Only worse because Samurai Ifraid is of a lower-Track then Revizer. Zero pulls through though, and in order to end it: he commands Samurai Ifraid to take the skies and crash back down on Killerken with his special move, Shooting Star Crash. Gen, after realizing defeat, takes his Killerken and retreats to the sea. After the not-so-fearsome battle, Zero and Co. pack their things and return back home to Metal Bey City. Benkei is on the top of cliff with Tsubasa and is yelling at the sunset and ocean.
