Ok. So the writing makes not much sense...
It's random quotes from Doubt. W
um... if you can be bothered to read the explanation...
Doubt revolves around a fictional cell phone game called "Rabbit Doubt". The players are rabbits in a colony; one of these players is randomly chosen to act as a wolf infiltrating the group. Each round, the rabbits guess which is the wolf as the rabbits are eaten one-by-one until none are left.
Four players of the "Rabbit Doubt" game Yū Aikawa, Eiji Hoshi, Haruka Akechi, Rei Hazama and a non player Mitsuki Hōyama meet to relax together. During the day, the group is rendered unconscious. They awaken in an abandoned psychiatric hospital to meet Hajime Komaba, a player who did not appear at the meeting and find Rei crucified. The group finds Rei's cell phone and realizes they are playing a real-life game of "Rabbit Doubt". To survive, the wolf, the liar, must die.
At the beggining of the manga when they were explaining the game they had this picture of cute little rabbits... hanging each other. Couldn't resist making something like it.
Doubt was created by and belongs to Yoshiki Tonogai
