As the world constructed around him begins to unravel, Takumi will discover that nothing - not even his own life - is what it appears to be. Welcome to Chaos;Head.
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, 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.
After Yui's death, Takuru's family tries its best to recover. Kurusu makes a shocking admission to Takuru that she's been hiding something from him. She's willing to do anything to find the killer, and she's getting very, very close...
