The NGHJS decide to stick around to observe the situation in case more kaiju return, and Yūta starts to see what he believes are ghosts. As a result of the overlapping universes, Yomogi, Yume, Koyomi, and Chise are transported to Yūta's world. While they have a happy reunion with Gauma, they have no means of returning to their home universe. Instead, Yomogi and his friends decide to help Yūta, Rikka, and Utsumi with their play. Gauma manages to meet the Princess, who advises him to move on from his past and look to the future. However, Yūta begins to notice several inconsistencies with the world until a second kaiju attacks. Gridman, DynaRex, and the NGJHS engage the kaiju and are assisted with the arrival of Knight and the 2nd. The kaiju is defeated, but a second Gridknight suddenly appears and apparently destroys Gridman. With Gridman's destruction, the NGJHS, the Dynazenon crew, Knight, and the 2nd all disappear with the exception of Yomogi.
The younger versions of Knight and the 2nd then arrive, revealing that Gridman had actually unconsciously created multiple universes. Some unknown force is attacking Gridman's consciousness, which is causing the universes he created to overlap. Knight and the 2nd urge Yūta to combine with Gridman, as he is the only one who can break him free. Multiple Kaiju then attack, with Knight and Yomogi doing their best to hold them off. Yūta reaches Junk and connects with Gridman with assistance from Akane in the real world. Akane frees Alexis Kerib from confinement and takes remote control of him, attacking the mastermind behind the assault on Gridman's mind, Mad Origin. Mad Origin reveals he is an embodiment of chaos, the antithesis of Gridman who wants to steal his ability to create universes. Gridman regains control of himself and summons the Dynazenon crew, the NGJHS, Knight, and the 2nd to battle Mad Origin and with everybody working together, they are able to defeat him thanks to Alexis Kerib's sacrifice.
With the battle over and the universes saved, Yomogi and his friends are sent back to their home universe. Akane apologizes to Knight for her poor treatment of him before returning to the real world. Gridman and the NGJHS return to the Hyper World, with Gauma finally letting go of his feelings for the Princess. Yūta, Rikka, and Utsumi rewrite their play, titled "Gridman Universe", which proves to be a huge success. After the festival, Yūta finally confesses his feelings to Rikka, and she reciprocates. In the real world, Akane meets up with her friends to clean up a polluted riverbank.
