Nice and Murasaki infiltrate Yokohamabane High School following a request from two students named Theo and Rei to search for their missing teacher, Yasuo Kitazawa. Sometime later, Art summons Nice and Murasaki after discovering the murdered Kitazawa in a burger restaurant and explains the serial murder case to them. Nice also steals Kitazawa's phone from the crime scene and obtains the six photos of Theo's bullies supposedly leaked on the internet. Nice then traces the poster's IP back to Kitazawa's home and deduces that he had been using his Realism Minimum to turn descriptions of the bullies' exploits into pictures which he then used to further his reputation over their exposure. Afterwards, as the Hamatora PI's establish a link between the photos and the recent serial bombings, Theo stumbles upon his former bully and the serial bomber, Kojima in his latest bombing attempt at the school using his Time Acceleration Minimum. However Nice and Murasaki show up just in time to foil the bombing. Afterwards, Art discovers that Kojima and the Gravity Holder obtained their abilities artificially which would require the use of a Minimum Holder's brain. Elsewhere, the serial killer admires his collection of brains.
