Plot
The movie opens with the school staff, Erich von Rerugen, Roswaal L Mathers, Wiz, Vanir, Pandora's Actor, Kurt von Rudersdorf, and Hans von Zettour, laying out the proper code of conduct to the watchers.

In Another World, a girl-shaped Golem is moving around some goods when the ground suddenly shakes. Spotting the source of the tremors, a rampaging Siege Golem, she heads toward it. The Golem is revealed to be chasing the members of the class, plus Naofumi, Raphtalia, and Filo. Several classmates try to hurt it or slow it down, to no effect: Puck shoots [El Huma] at it, Aqua tries distracting it, Naofumi summons several [Air strike Shields] in its path, and Darkness attempts to use herself as a meatshield but is stopped by Wilibald and Rhiner. Demiurge recognizes the creature as being from YGGDRASIL, explaining to the others that it is a top-tier monster and that their chances of beating it are roughly 0%.

As the class crosses a bridge, with the golem still chasing them, Kazuma tries using [Steal] to remove its core and shut it down. However, not wanting to be outshined, Magumin casts [Explosion] on the golem, getting in Kazuma's way and causing him to accidentally steal her panties. While failing to do damage, the [Explosion] causes the golem to fall into the river. However, this also creates a shockwave that blows everyone away. Having observed the whole ordeal, the girl is shocked to find that other people have appeared in the world.

Flashing back to a little while ago, the classmates are still at the school and going about their day: Tanya's squad does maintenance on their equipment, the Floor Guardians, Kazuma's party, and Emilia Camp are bonding, and Naofumi's party drops by to deliver some papers. Ainz pets Chomusuke when a portal suddenly appears behind him and sucks him in before he can react followed by the other classmates. Afterward, the classmates, minus Ainz and Chomusuke who got separated, find themselves in yet another world where they are immediately attacked by the Siege Golem.

Back in the present, the classmates find themselves separated across the world. Elsewhere, Ainz and Chomusuke discover a storehouse containing countless golems that the Overlord recognizes as being from YGGDRASIL and a control panel to manipulate them.

Naofumi, Aqua, Mare, Ram, Rem, Wilibald, and Rhiner are attacked by an army of low-tier golems. While they can fight them off, more just keep appearing. Fortunately, Naofumi has a plan and imprisons himself, Ram, and Rem inside his [Shield Prison] before having Wilibald and Rhiner fly them to safety. Rem also does something similar by having Aqua and Mare ride a block of ice she created using [Ul Huma]. After flying for a while the group notices a village and decides to land nearby, causing them to get noticed by one of the inhabitants.

Meanwhile, the girl locates another group, Subaru, Beatrice, Puck, Demiurge, Shalltear, Aura, Darkness, Visha, and Filo, but does not know how to approach them. However, when they are about to attack a rampaging low-tier golem, she intervenes and calms it down. The group demand to know who she is and she flamboyantly introduces herself as Pantagruel, the "guardian of [this] world", causing them to realize that she is a chūnibyō. Pantagruel continues to explain that the golems that inhabit this world are out of control and invites them to come with her to her home village, enticing them by revealing that there is a human living there.

TBA

The credits showcase a series of illustrations telling the story of Pantagruel's past: her creator, Kikotenshin Nekonyan, was transported to Another World, where he met the Head Researcher and they began developing golems together. However, this eventually culminated in the creation of the Strongest Golem, which then promptly went on a rampage. To defeat it, Nekonyan and the Researcher created Pantagruel, and they successfully shut the ramping golem down. Afterward, the Researcher departed back to his world while Nekonyan stayed behind with Pantagruel until he died of natural causes, leaving her all alone until she met Alec and Vera.

In a post-credit scene, it is revealed that, while the class was away, Otto Suwen and Garfiel Tinsel transferred in, much to Subaru's charging. Roswaal then states that their "school life will continue".
