Trapped in a real-life version of the cell phone survival game Rabbit Doubt, Yuu refuses to believe that any one of his fellow prisoners could be the vicious wolf, not even when obvious clues point to Haruka. But the party of abductees has already lost two of its own, and history indicates that the wolf is far from done hunting rabbits. The appearance of a new door encourages hope, but if the wolf is still prowling among them, will anyone actually be left standing at the end to walk through the door? Find out in the spine-tingling conclusion to Yoshiki Tonogai's Doubt!
