Plot
Due to SaiDain's awakening, the Gekirangers' full power awakens, along with Rio and Mere. However, the Kensei still encased in the Dōkokugan makes Jyan feel guilty and he runs off in haste to find Maku to break the Ringi. After drinking the siphoned lifeforce of the Kensei, Maku is challenged by Rio, whom manages to match him without even turning into Black Lion Rio. Maku however, still considers himself superior decides to handle the Gekirangers himself while allowing Rio to live long enough to see his rivals' demise. He uses the entire Rinshī army to attack the city to lure them out, with the Gekirangers fighting the hordes of Rinshī. Jyan sensed a power what he thought to be Maku, but was actually Rio. Rio informs Jyan that if he was the power he sense then he must have surpassed Maku, and the two fight. As Rio thought, they both had become stronger than before due to being affected by the Beast Power Bloom. With that, Rio tells Geki Red to kill Maku and end their masters' war before they settle their own. Back at the city, Maku easily overpowers the four Gekirangers and was about to kill them when Super Geki Red arrives in time and turns the tables with using the Super SaiBlade to beat the Kenma in a one-on-one battle with his own Kageki Hard Diamond. After encouraging the others to feel their full power, the five Gekirangers combine their qi and signature attacks to defeat Maku. However, Maku enlarges and Geki Fire and Geki Tohja Wolf are overpowered by him. SaiDaiOh enters and it and Maku prove to be equals as sun sets on the battlefield. But the Gekirangers' refusal to give up results with a new formation: SaiDaiGeki Fire. With all three Geki Jūken qi combined together, Maku is finally destroyed. Maku's death releases the Kensei from the Dōkokugan Ringi. While the fight occurs, Rageku is horrified that Maku was outmatched by weaker opponents. Long then appears, telling her that she served her purpose and liquifies her before taking her staff to present to Rio. With the Three Kenma dead and Rio mastering their lessons, Long offers him the chance to master a power greater than both Jūken schools: the Gen Jūken.
