A Gust of Wind Slices Her Classmates in Half – She’s the Only One Left

Overview

Mitsuko begins the story in a typical school-morning routine—buses full of cheerful girls, but Mitsuko is the odd one out because she keeps writing notes. Her friends tease her, and one snatches her notebook just as Mitsuko bends to pick up her pen. In that moment, a horrifying invisible force—wind—appears and slices the bus and everything nearby in half. Mitsuko survives only because she’s crouched, then spends the rest of the opening sequence running as the wind kills classmates, cyclists, and even the girl she tries to save.

Escape Attempts and Reality “Branching”

Traumatized, Mitsuko reaches a river where the water is full of corpses. She steals clothes from a dead body and eventually arrives at a school where her best friend Aki is waiting—though Mitsuko can barely believe it. Another gust of wind terrifies her, and after Mitsuko explains what happened, Aki takes over: they attempt to escape the world’s “rules” by skipping class and running into the forest.

At a lake, Aki and her friends test whether reality can “branch.” Sura jokes about infinite alternate realities, throws a stone into the lake, and a giant crocodile appears. Then Tai is eaten in another universe but unaffected here, proving their reality is being controlled like a system with multiple outcomes.

The Game Escalates: Massacre and Resets

The “game” escalates in class. A pillow saves Mitsuko by preventing her from bending at the wrong time. Immediately afterward, a teacher pulls out a minigun and massacres everyone. Mitsuko barely escapes as teachers keep shooting. She eventually trips—this time the wind catches up and kills the rest, leaving her as the sole survivor who reaches a police station.

Police Station Twist: Mitsuko as “Ko”

At the police station, an officer calls her by another name—“Ko.” He checks her appearance in a mirror and places her into a police car because a “new” version of Mitsuko is about to get married. The story reboots again: congratulations on the street, wedding preparations, and mocking girls.

Aki (still controlling events) kills the intruders and arms Mitsuko with a broken glass bottle to cause chaos at the altar. The groom is replaced by a coffin holding a pig-masked figure. Mitsuko’s glass attack sparks panic so she and Aki can flee—until more “teacher” pursuers arrive.

Identity Changes, Impossible Encounters, and Aki’s Strategy

During the run, Mitsuko’s identity keeps changing—marathon runner, different names. She encounters dead friends who “shouldn’t be alive.” Sura insists the only way out is to escape the world itself, and Aki offers a crucial strategy: to change fate, Mitsuko must do something “impossible” within this reality.

Mitsuko finds a cave filled with students in school uniforms. A girl tries to kill her for surviving, but Aki intervenes and takes Mitsuko deeper into the plan. Mitsuko discovers she has a cable implanted in her hand—something that could let her “pull out” and return to the real world.

Mitsuko refuses at first, fearing it will kill Aki. Aki then snaps the logic into place: this world is fictional and controlled, and Aki’s role depends on Mitsuko acting as the “main character.” Mitsuko pulls the cable, and Aki is destroyed/split, revealing the cruel cost of breaking the system.

Entering “Tag” and the Final Reveal

Mitsuko passes through a gate into a male-only world. Men treat her reality like a violent 3D survival horror game called “Tag,” complete with posters of Mitsuko and the others.

The final reveal lands: an older man designed the game and used Mitsuko’s and her friends’ DNA to create clones, allowing her to “die” repeatedly through trials. The “final stage” is actually a sick, personal wish—sleeping with the younger version of the old man.

Remembering the earlier rule about changing fate through impossible action, Mitsuko refuses to play along. Instead, she chokes the young boy and then kills the old man using his cane, disrupting the game’s intended script.

Ending: Overwriting Timelines

In the finale, Mitsuko effectively overwrites all timelines at once. She dies in multiple scenarios—the bus, wedding hall, and marathon-like settings—right at the start. Then she wakes in a snow-covered real-world setting, implying she has finally escaped the fictional loop.

Standout Highlights / Key Reactions

• Invisible wind as the killer, slicing people and vehicles with instant gore.
• Survival by bending at the right moment, echoed later by the “pillow saves her” scene.
• Sura’s alternate-reality joke, including proof that one branch can affect outcomes while another remains “untouched” (Tai).
• The world reset structure: school → escape → massacre → police station → wedding → identity changes → cave.
• The minigun teacher escalation, repeated slaughter, and reality restarting.
• Aki as both protector and controller, ultimately sacrificing herself when Mitsuko uses the escape cable.
• Final twist: Mitsuko isn’t merely trapped—she’s part of a DNA-based game system, and she breaks the “final stage” by acting outside the script.
