Shibuya is rocked by a series of brutal murders. 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 than he expected!

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.

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

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.
