Years after an Earthquake destroyed much of downtown Shibuya, the city is rocked by a series of brutal murders. A man eats his own hand. A woman rips open her own stomach and stuffs a speaker inside. Takuru Miyashiro, a student at Hekiho Academy, is investigating these murders as part of the school's newspaper club. But when he finds a break in the case, it turns out to be closer to him than he ever thought...

After Takuru is taken in by the police, Kurusu wants him to give up the case. But he's noticed something... the sumo stickers that have been placed all around town have something in common with the murder scenes. He puts up a hidden camera near a wall of sumo stickers that just appeared. But when Kurusu finds out, she leaves in the middle of the night to take it down...

After Kurusu is stabbed, the newspaper club is placed on hiatus. But Watabe, an important reporter with Niconiya News, wants to interview them about the things they've noticed with the sumo stickers and the hotel murder. Watabe's visit to the school, however, takes an unexpected and terrifying turn...

After Kurusu is stabbed, Takuru infiltrates AH Tokyo General Hospital, hoping to find the creator of the sumo stickers. When he gets there, he, Onoe, and Itou are forced to hide in the basement to avoid being spotted. Inside the basement's autopsy room, they find a secret entrance that leads to an underground laboratory where terrible experiments were once conducted. Takuru thinks he's been here before...

Takuru and the others find a survivor in the basement of the hospital. Her name is Uki Yamazoe, and she's a young girl who looks to be around 10 years old. After seeing how Takuru was able to infiltrate the hospital, Kunosato realizes that he must be a "Gigalomaniac", a psychic with the power to make his delusions reality. But being a psychic doesn't come with just benefits, as one night he runs into someone who is trying to kill him...

It's October 23rd, the day of the New Generation Madness incident, and it's time for the next murder. Takuru and his friends are terrified that they're going to be a target, and so they stay up all night at Cafe LAX. But when Takuru opens the cafe menu once last time in the late hours of the evening, he finds a Sumo Sticker stuck to one of the pages...
