While in the middle of fighting, the Gekirangers and Mere are telported to Hong Kong, along with Rio and various other martial artists around the world. Just as Rio and Jyan were about to fight, they meet the mysterious Lao Fan before seeing others brought to the island as well. They all then meet Miranda, the secretary to Yang, a media mogul who brought them all together for the Kenkonitteki Martial Arts Tournament (乾坤一擲武術会 Kenkonitteki Bujutsukai?) to prove who's the strongest of them all. The first round of fighting leaves the Gekirangers, their Rinjūken rivals, Lao, Barnard Koyama, and Big the Goto as the winners. At the banquet hall, Ran, Retu, Rio, and Mere meet Yang Lo himself while Jyan follow Lao Fan and learns she's actually a member of the Hong Kong police who is investigating Yang, who founded Mechung Fu and used his tournament to gather strongest fighters as part of his plan to rule the world, finding the ideal Ki he needs: from the Jūken users. Geki Blue, Geki Yellow, Rio, and Mere attempt to fight off Miranda as Yang takes his leave, finding Jyan and Lao in his base of operations before they restrained him. However, the Ki Miranda collected before she died transfers to Yang's computer, transforming Yang into a cyborg Beastman before he starts absorbing more Ki to become a supreme being. The Gekirangers battle Yang Lo, refusing to give up in spite of him being stronger than them. Evading his defeat, Yan activates his giant robot Mechannon to terrorize the city. When GekiTohja proves no match for Mechannon, Rio and Mere take offense to Yang's comments on the Jūken style and are forced to help the Gekirangers by summoning Rin Jūken Akugata#RinBeastsRinLion and RinChameleon to combine with GekiTohja to form GekiRinTohja to destroy Mechannon, killing Yang in the process. Once the fight is over, in spite of the Gekirangers' amazement at the power of the united Jūken schools, Rio takes his leave with Mere telling them that nothing changed between them. The next day, Lao thanks the Gekirangers as they were about to leave for Japan when Miki, Natsume, and Xia Fu arrive for a vacation in Hong Kong.
