Input: Kouichi Sakakibara:  Extra One ?
Mei Misaki: Twenty five years ago , shortly after the start of the new management , they realized that a desk was missing in the classroom , even though they had prepared enough seats for all students .
Kouichi Sakakibara: Could not they just check the lists ?
Mei Misaki: They did , but it was useless . The list of students had been altered to be inconsistent . They only lacked a desk .
Kouichi Sakakibara: Did someone rewrote the lists ?
Mei Misaki: I used the word " altered " figuratively . They say that memories of all had been changed .
Kouichi Sakakibara: Uh ?
Mei Misaki: That sounds impossible , right ? But I guess that 's true . They said that this phenomenon could happen .
Kouichi Sakakibara: Phenomenon ?
Mei Misaki: At first , everyone thought it was just a mistake and they do n't gave a damn about it . But starting April , people connected to the class , began to die each month .
Kouichi Sakakibara: Does each month ? All year ?
Mei Misaki: This year I think were six students and ten relatives . Quite unusual , is n't it ? This has continued in the class three since .
Kouichi Sakakibara: Then , a third year student from the class named Misaki , died twenty - six years ago ... And starting next year , somehow , there was an additional student in class . Then , people connected to the class began to die each month . But ... Why do people die when there is a extra student ?
Mei Misaki: No one knows why . This is how it happens . Moreover , the extra _ one _ is ... someone dead .
