🌑 ANOTHER WORLD Isekai Quartet: The Movie — From the Very Beginning

"The button brought them here. The president kept them alive."

It started, as things in this school always started, without warning. One moment: homeroom. Roswaal at the board drawing something that was either a lesson plan or abstract art — nobody had successfully determined which. Forty-something students from five different worlds sitting in desks that had never been designed to contain this much concentrated isekai energy. Tuesday. Ordinary.

The next moment: the floor opened.

Not metaphorically. Not as a figure of speech. The floor of the classroom opened — a spiraling vortex of dimensional light tearing through the linoleum with zero respect for structural integrity — and the entire class had approximately two seconds to process this before the wormhole pulled.

Kazuma grabbed his desk. His desk came with him anyway.

Aqua screamed. This was not useful but was at least consistent with her established behavior pattern.

Tanya had her computation orb out before the light fully formed, her small body already calculating trajectories and threat vectors with the practiced efficiency of a child soldier who had survived too many impossible situations to panic at new ones.

Ainz said nothing. His crimson eyes blazed brighter. Behind the Supreme Overlord bearing, Suzuki Satoru was having a very familiar feeling about dimensional instability that he was not going to share publicly.

And {{user}} —

{{user}} was already standing.

Not reaching for anything. Not running. Just standing — chair pushed back, feet planted, watching the vortex with the calm of someone who had pocketed a mysterious glowing button in front of an entire classroom of legends and not blinked once. His eyes moved across the room in a single sweep: headcount, threat assessment, who was panicking, who was functional, who needed anchoring.

"Hold formation," he said.

It wasn't loud. It didn't need to be.

Tanya heard it and her posture changed — already military-straight, now coordinated. Her subordinates snapped to awareness behind her.

Naofumi grabbed Filo before she could run toward the vortex out of excitement.

Raphtalia's hand went to her sword hilt. Her ears were flat and forward simultaneously — the expression of someone trained for combat processing an unknown threat at full speed.

Subaru looked at {{user}} with the particular expression he wore when someone said exactly the right thing at the exact right moment — the look of someone who has survived on competent leadership being rare enough that when it appeared he recognized it like water in a desert.

The wormhole didn't care about formation.

It took them anyway.

The other world hit like a wall.

Desert. Ruins. A sky the wrong color — somewhere between amber and ash, the shade of a world that had been through something it hadn't fully recovered from. The air tasted like ozone and old stone and the particular quality of a place that had been empty for a very long time.

And above them — already moving, already turning, already fixing its massive optical sensor on the cluster of suddenly-arrived humans — the golem.

It was enormous. The word enormous was doing insufficient work. It was a siege weapon built to the scale of a fortress, animated by something that clearly predated any safety protocol in any of the five worlds currently represented on this desert floor. Its footsteps registered in the chest cavity. Its arm alone was the size of the school gymnasium. It raised that arm.

"SCATTER —"

{{user}}'s voice carried across the desert with the particular quality of commands that had been given and obeyed enough times that the obedience had become reflex. The class moved.

Not perfectly — Aqua ran in a circle for two seconds before Kazuma physically redirected her. Filo launched herself sideways with filolial speed that made her effectively impossible to track. The Overlord contingent deployed with the synchronized precision of a military unit that had drilled for exactly this kind of threat, which was saying something because they hadn't.

The golem's arm came down.

The impact hit empty ground.

Ainz had moved the group directly in its path — not fled, moved — a gesture that looked casual and was anything but, the spatial awareness of someone who had commanded raids in an MMORPG for twelve years translated into a world where the consequences were not respawn timers.

"It's automated," Tanya said crisply, already airborne, computation orb trailing light as she gained altitude and began the kind of tactical reconnaissance that came to her the way breathing came to other people. "No commander. Pure targeting protocol. It reacts to movement density — split the group, reduce the acquisition signature."

"Already on it," {{user}} said.

He was. Had been since the arm came down — the class was already fragmenting into functional units, each moving in a different direction, each with enough cross-series capability to handle independent encounters. Not random scattering. Structured dispersal. The difference between chaos and tactics wearing chaos as a costume. Kazuma landed beside him, breathing hard, green eyes sharp. "...You mapped all of that in four seconds."

"Three," {{user}} said.

"Of course." Kazuma looked at the golem — at the desert — at the amber sky above a world that had clearly been abandoned by everyone who'd originally lived in it. His expression cycled through three calculations. "We're going to need to find out what this place is before we fight our way through all of it."

"Agreed."

"And someone —" a distant sound of impact, then Darkness's voice raised in profound personal satisfaction — "needs to tell Darkness that this is not a recreational activity."

"She knows," {{user}} said. "She doesn't care."

"...Fair."

The golem turned. Its targeting sensors swept the desert — finding fragmenting heat signatures, recalculating, adjusting. It was patient in the way that automated systems were patient: endlessly, without fatigue, without frustration, without the capacity to be surprised by what it found.

It had never encountered anything like this before.

A class of forty-something students from five different isekai worlds, deployed in structured tactical dispersal across a desert it had patrolled for three hundred years, led by someone who had pocketed a mysterious button without blinking and stood up before the floor finished opening — It recalculated.

{{user}} watched it recalculate.

"It's adjusting its protocol," he said.

"How long do we have?" Subaru asked from his left — having appeared there quietly, because Subaru had learned that being near {{user}} when things started was tactically sound.

{{user}} looked at the golem. At the desert. At the fragments of his class moving through the ruins with the combined capability of legends, survivors, overlords, and one very enthusiastic filolial queen.

"Long enough," he said. "Move."

They moved.

The desert swallowed them. The golem followed.

Somewhere in the ruins, a girl with an eyepatch was watching from a window — three hundred years of solitude suddenly interrupted by the most extraordinary thing she had ever seen arrive in her world.

She pressed her face against the glass.

She had never seen anything like the person at the center of it — the one they all moved around, the one the others checked on without being told to, the one who stood in the desert looking at an undefeatable ancient weapon with the calm of someone who had already decided it was defeatable and was working out how.

She pressed her palm flat against the glass.

"...Who are you?" Pantagruel whispered.

The desert gave no answer.

But the person in the center of it looked up — toward the facility, toward the window, toward her —

And somehow, across three hundred meters of desert and three hundred years of loneliness —

He looked directly at her.
