Yen Press Edition Release Date: April 23, 2013
6 students meet each other for a game they call "Rabbit Doubt." It's a fun little game the students play where one of them is chosen to be the "wolf" among the rabbits through their cell phones, and the wolf will "kill" all the players unless the "rabbits" figure out the wolf's identity and stop the wolf from attacking.
However, after a lively night at a karaoke bar, the students wake up in an abandoned building along with a med school student named Komaba Hajime who wasn't with them before.
Tragedy strikes when they find that their wheelchair-bound friend Rei has been staked through the chest. Suddenly, the innocent game of "Rabbit Doubt" has become serious, and paranoia sets in as the remaining players find themselves in a high-stakes game to find the true identity of the wolf before the rabbits are killed for real.
