On Year

On Year is the name given to a school year in which an unidentified extra person enters Yomiyama North Middle School Third-Year Class 3 and disasters strike people connected with the class. Its decisive significance is that it transforms a classroom into a closed system of recurring danger: records and memories are altered so that the extra person’s presence appears normal, while students and relatives become vulnerable to accidents, illness, suicide, and murder.

Definition and Conditions

An On Year is distinguished from an “off year,” or a year in which the disasters do not occur. The condition is not simply a period marked by bad luck. It depends on the presence of an extra person who should not be in the class, referred to also as the casualty, and on the resulting deaths of people linked to Third-Year Class 3. The phenomenon therefore combines a hidden identity with a widening circle of consequences.

The class’s own explanations give the condition an informational as well as a physical structure. While the extra person remains hidden, records and memories are tampered with throughout the surrounding system. Details that would ordinarily be impossible are made to seem coherent, and no one recognizes the casualty’s true identity. Mr. Chibiki confirms that this alteration genuinely occurs, without hesitation, making distorted recollection part of the operating condition rather than a mere rumor.

Historical Pattern

Mr. Chibiki’s experience in 1976 demonstrates the scale of an On Year. The preceding year, 1975, had been an off year, and he accepted responsibility for Third-Year Class 3 in 1976 in the hope that the disasters might have ended. Instead, 1976 was an On Year. Five students in the class and nine immediate family members died, fourteen people in all. Their deaths took multiple forms: accident, illness, suicide, and murder.

Changing classrooms after the summer break did not stop the disasters. This failure weakened the idea that the classroom itself was the source of the curse. The deaths continued until graduation in March, when the extra person vanished; afterward, however, Mr. Chibiki could not remember who that person had been. Even as head teacher, he could only later identify a likely candidate through collected information, without recovering the memories as personal experience. The On Year thus ends with both physical catastrophe and retrospective uncertainty.

Attempts to Control the Condition

The “not there” strategy developed as an attempt to counter an On Year by making one member of the class socially absent. Because people with no direct link to Third-Year Class 3 are considered safe, Mr. Chibiki can interact normally with students such as Mei Misaki and Koichi Sakakibara. By contrast, the class tries to suspend recognition of a selected student, hoping to restore balance by reducing the number of acknowledged participants.

The strategy’s history is uncertain but measurable. It began ten years before the current events. In 1988, the first year of its use, the extra person had apparently entered the class in April, yet no one died. That apparent success established the tradition that the strategy should be used in an On Year. In the five subsequent On Years before the current one, excluding the current year, the strategy succeeded twice and failed twice, while another attempt failed partway through the year. The record makes clear that the strategy is neither a proven cure nor a stable rule; it is a desperate institutional response to a recurring condition.

Manifestation in the Current Class

The current Third-Year Class 3 is explicitly described as being placed in peculiar circumstances. Mr. Chibiki acknowledges this before the class and plans to accompany students on their ascent of Yomiyama, presenting himself as someone who can help them avoid accidents. His careful reassurance reveals the tension between ordinary school supervision and the exceptional danger imposed by an On Year.

The class’s efforts to increase the number of students treated as “not there” to two have no effect. Once this attempt is abandoned, the students gradually stop ignoring Mei Misaki and Koichi Sakakibara. The change is not produced by a formal decision but by an invisible shift in behavior, marked by Mr. Kubodera’s death. Naoya Teshigawara begins acting as though Mei exists and addresses her directly, showing that the social exclusion associated with the strategy has been relaxed without eliminating the underlying danger.

The condition also reaches beyond the schoolroom into collective rituals and spaces. Third-Year Class 3 undertakes a two-night, three-day camping trip beginning on August 8 at Sakitani Memorial Hall, a school-owned lodge at the foot of Yomiyama, after the head teacher proposes visiting Yomiyama Shrine. The shrine is badly maintained and appears forsaken, but the students clean it together and become convinced that the act might break the curse. The head teacher assures them that everything will be all right; the attempt fails, and the curse proves resistant to such simple ritual repair.

Social Order and Consequences

An On Year suspends normal recognition. The class treats certain people as though they are absent, while the actual extra person is incorporated into records, memories, and daily routines as though present. This produces a paradoxical order in which social acknowledgment becomes a protective instrument, even though withholding acknowledgment also creates isolation and ethical strain. Mr. Kubodera and most of the class know the truth about the family relationship between Koichi Sakakibara and Reiko Mikami, yet the school’s rules require them to behave as strangers there: he is the transfer student Sakakibara, and she is Ms. Mikami.

The same tension appears when Mr. Chibiki responds to an apparent medical crisis. He insists that the student should be taken to the hospital and tells the frightened class that the attack is a familiar consequence of the student’s condition, not an extraordinary event or freak accident. His calmness is meant to prevent panic, but the narrator recognizes that he is lying. In an On Year, reassurance becomes part of containment: adults preserve the appearance of normality even while the class’s fear signals that ordinary explanations no longer suffice.

The condition’s greatest consequence is therefore not only the number or variety of deaths. It alters memory, relationships, movement, ritual, and authority. Students must live inside a system whose rules are partly inherited, partly improvised, and repeatedly tested by failure. The On Year makes the class both a community and an exception, binding its members together through shared procedures while denying them the ordinary certainty of who belongs within it.
