Uneasy Classroom Silence

A Hostile Peace
The New Arrangement
Koichi Sakakibara and Mei Misaki are treated as though they do not exist. Teachers and classmates refuse to acknowledge them, creating an artificial silence around the two students.
Freedom and Fear
The arrangement gives them unexpected freedom, but the calm is built over dread. Every ordinary school day becomes a test of whether the disasters have truly been contained.
Roofside Companionship

Solitude Shared
Lunch Above School
Koichi Sakakibara and Mei Misaki eat together on the roof, exchanging small personal details about cooking, art, family, and their uncertain futures.
A Private World
Their conversations turn enforced isolation into intimacy. The strategy separates them from the class, but it also gives them a space where their connection can develop without supervision.
Art Club Return

The Absent Artist
A Room Full of Evidence
Mei Misaki visits the art club room with Koichi Sakakibara. Her unfinished portrait of Kirika Misaki, with its divided face, reveals an artistic attempt to confront painful family tensions.
The Club’s Unease
Yuya Mochizuki must remove the younger students when Mei appears. The scene shows how the strategy distorts ordinary relationships and turns even a clubroom into contested territory.
Chibiki’s Archive

The Observer’s Evidence
The Librarian’s Testimony
Tatsuji Chibiki explains the history of the phenomenon, including the first casualty, the recurring deaths, and the way memories and records become altered.
A Theory Without Logic
His archive cannot explain how the impossible occurs. It can only establish patterns: the phenomenon behaves like a supernatural natural event, and the “Not There” Strategy sometimes reduces its reach.
The Failed Experiment

The Second Absence Fails
Kubodera’s Collapse
After Mr. Kubodera kills himself in front of the class, the attempt to treat both Koichi Sakakibara and Mei Misaki as absent is abandoned.
The Disaster Continues
The death of Mr. Kubodera and his mother proves that increasing the number of absent students has not stopped the calamities. The class loses its fragile confidence in procedural protection.
