Summary
Mr. Kubodera, homeroom teacher of Class 3-3, stabs himself to death in front of his class, leaving the students completely traumatized. It is later revealed that before killing himself, Kubodera had also murdered his ailing mother. This event proves that the countermeasures in effect so far have been unsuccessful so Mei and Kouichi's existence are once again acknowledged by their classmates. Afterwards, Kouichi meets up with Yuuya, Naoya, and Izumi in a cafe, where Yuuya's older sister tells them about Katsumi Matsunaga. A former class 3-3 student who managed to stop the phenomenon in 1983 and left information on how he did it for future students to find. However, it seems as though he does not remember what or where this information may be. Kōichi explains the situation to Mei, including his fear of being the dead one behind this year's calamity, to which she eerily responds that he is not the one.
