The book is a collection of Zettai Zetsubō Kodaka articles that ran biweekly in Famitsu magazine for 2.5 years (890 days). Zettai Zetsubō Kodaka articles were written by Kodaka, and covered development of the history of the series, and commentary on the then-latest entries to the franchise, such as behind-the-scenes details of Danganronpa 3: The End of Hope's Peak High School episodes and Danganronpa Gaiden: Killer Killer.
It was released on March 30th, 2017, with a special signing event at Super Danganronpa 2: Sayonara Zetsubō Gakuen THE STAGE 2017 where Kodaka signed copies of the book. Who purchased the novel at the event also earned a copy of the card featuring a logoless version of the cover illustration.
