A mysterious space sage entrusts Yuma with challenges that surpass the limits of his imagination with a stake too high. He asks, "Should you fail… then you… will lose your power as Arc." The burden of protecting Hoshimoto City alongside SKIP members are twisted by Sascal, who manipulates them, sending challenge after challenge toward Yuma. Battling giant kaiju, an evil alien bent on destruction, and a warped dimension where even time itself is distorted, Yuma must confront the ultimate test. Will he... will Ultraman Arc overcome the greatest challenge yet and protect the future, surpassing the limits of the power of imagination?
