Danganronpa Another Episode Collectibles/Books

Books are a type of collectible featured in Danganronpa Another Episode: Ultra Despair Girls. They contain various bits of flavor text, including novels written by Toko Fukawa.

Background
As you progress with Komaru Naegi and Toko Fukawa through Towa City as part of the main objective of the game, you will stumble upon many books left behind by the people of the city before it fell into chaos. The books, as well as other collectibles in the game, appear in the overworld as a small glittering object. As you find a book and pick it up, the screen automatically goes on to display its contents. Reading the books will trigger a conversation between Komaru and Toko, which gives an insight into the book and the personal lives of the protagonists.

The books can be divided to several subcategories according to publisher which include books released by the Towa Group featuring info about the city and its history, books of propaganda published by Ultimate Despair, and miscellaneous works of fiction.

Trivia

 * The publishing company for Billy Milligan Royale "SpiChun Bunk0" is reference to the company Spike Chunsoft.
 * The title of the book Billy Milligan Royale, which is a novel about a girl with multiple personalities, is based on the real-world Billy Milligan, a man who was the subject of a highly publicised court case in late 1970's, and was diagnosed with dissociative identity disorder (abbreviated DID), also known as multiple personality disorder. Milligan's lawyers pleaded insanity and he was acquitted of his multiple crimes as a result - instead being sent to multiple psychiatric institutions; making Billy Milligan the first person in history to raise an insanity defense over DID and the first to do so successfully.
 * Toko Fukawa is explicitly said to have DID as well, with her one and only alternate personality being Genocide Jack.
 * This book title also references Battle Royale (バトル・ロワイアル), a 1999 Japanese dystopian horror novel by Koushun Takami, a story in which randomly selected junior high school students are forced by the military to fight each other to the death until only one survives.
 * The author for Right to Not Kill's surname is a reference to the creator of Danganronpa, Kazutaka Kodaka.
