Having absorbed Idea, Gyanon summons an army of Horrors and ushers them to Earth through the Amber Rock Valley dig site's portal. Rekka and Jabi intercept the incoming Horrors before receiving aid from Shiguto and the other Makai Priests while Garo arrives on G?ten to aid his fellow Makai Knights in destroying the Horrors' portal then charges at Gyanon. Though revealing that Sigma's darkness reviving him was by mere chance, Gyanon reveals his intention to bring all Horrors into the human world. After Gyannon repels him and the Makai Knights attempt to cut of one of Idea's legs. However, Idea regenerates its severed limb, disarming Rei and Wataru before making its way to the center of a circle of pillars that would transport it to the human world. Garo makes a risky move by attacking the upper tower of Idea to halt its entry with the Makai Priests providing suppression fire with their combined magics to keep Idea down. Reo reveals the exposed core that can be damaged with the Shooting Star of Light Arrow technique that he prepares as Tsubasa comes and relieves Wataru. Garo, Zero, and Dan charge on their Mad? Horses as Gyanon unleashes Idea's built-in army of G?ry? to battle the three Makai Knights while having Idea raise back up. The fight seems hopeless until an army of Makai Knights joins the battle to stop Gyanon. As Reo sends a note to Jabi, the Makai Knights begin destroying the transport pillars, trapping Idea in the True Demon World.
