The classroom I hated so much has now become the only safe zone. Probably...
An ordinary school has transformed into a mysterious space. The school continues to expand, and it's unclear if an exit even exists. Students have formed factions by class, using their classrooms as bases, organizing armies, and engaging in alliances or wars. Each class acts independently, and no one knows why they are trapped in the school. Each class fights or negotiates to occupy classrooms they believe are safe or closer to an exit. During a reconnaissance mission, a photo taken in June of last year of Class 2-4—a class that shouldn't even exist—is discovered... (The created characters are just the core figures; there are others besides them.)
