Yuuya Mochizuki is a student at Yomiyama North Middle School, Class 3-3. He is one of the older members of the art club, one of Naoya's best friends, and has an older half-sister named Tomoka who works at a cafe. He is calm, innocent, patient, quiet around strangers and a bit shy, but is cheerful and sociable around his friends. Mochizuki is good friends with Naoya Teshigawara and becomes Sakakibara's first friend from Yomiyama North Middle School; he was also fairly close to Ikuo Takabayashi and was horrified when the other boy died. Yuuya seems to be one of the few students of class 3-3 everyone likes (a frustrated Izumi yells at him once, but mostly out of being angry with herself, and even Takako only seems to find him mildly irritating, as he's one of the few people she behaves playfully with). He was a fixture of the art club as one of their senpai (the other being Mei); he uses this to her disadvantage in an attempt to keep her isolated by luring the rest of the club away when Mei and Kouichi attempted to visit.

In 1972, a popular student in Yomiyama North Middle School's class 3-3 named Misaki passed away during the school year. Since then, the town of Yomiyama has been shrouded by a fearful atmosphere, from the dark secrets hidden deep within. Twenty-six years later, 15-year-old Kouichi Sakakibara transfers into class 3-3 of Yomiyama North and soon after discovers that a strange, gloomy mood seems to hang over all the students. He also finds himself drawn to the mysterious, eyepatch-wearing student Mei Misaki; however, the rest of the class and the teachers seem to treat her like she doesn't exist. Paying no heed to warnings from everyone including Mei herself, Kouichi begins to get closer not only to her, but also to the truth behind the gruesome phenomenon plaguing class 3-3 of Yomiyama North. Another follows Kouichi, Mei, and their classmates as they are pulled into the enigma surrounding a series of inevitable, tragic events—but unraveling the horror of Yomiyama may just cost them the ultimate price.
