Summary: "There's a game based on lies and deception growing popular in Japan. The game is called 'Rabbit Doubt' and it is played on cellular phones. The premise of the game is that all of the players are rabbits in a colony, and one amongst them is randomly chosen to be a wolf that has infiltrated the group of rabbits. Every round, the wolf kills off a rabbit, and every round, the group tries to figure out which of the rabbits is actually a wolf in disguise. Sometimes the kids who play this game decide to meet up in person, and Yuu, Mitsuki, Rei, Hajime, Eiji, and Haruka have done just that. Unfortunately, while the group is enjoying themselves at a karaoke club, they are rendered unconscious and awake inside what appears to be an old, run down mental hospital. They soon discover someone among them has decided to take on the mantle of the wolf and has already killed once. As their situation grows more dire, their trust and camaraderie quickly dissolves and they begin to accuse one another, while the wolf continues to pick them off, one by one. Who is the wolf, and can they be stopped before everyone meets a very unpleasant end?"

Review: "Enter “Doubt”: a gore manga with a plot. A plot that revolves around a group of “Rabbits” (i.e. the protagonists) to find the “Wolf”, as illustrated in the very beginning of the book—like a cruel, taunting tease of what is to come. Needless to say, as people begin to di...e within the group, people go absolutely nuts and start to accuse people, exact revenge, and have their whole world cave in on them.
Now, mind you, this specific plot has been done before—“Battle Royale”, anyone?—but that isn’t a downside, at all. Actually, the execution of said cliché plot is what’s so refreshing and engrossing. It’s a mystery who-done-it that piles the mystery on, slowly answering each one. You become so engrossed in the mystery and the dark, dank atmosphere that you could care less on that fact.
The only down-side to this is that the characters aren’t all that intriguing, you don’t really feel for the main character (Yuu), and that was a bit disappointing due to how much it excelled in areas that I find particularly important—except it lags greatly in this one field. "

My review: I really intriguing storyline. It reminded me in a way of the Saw movies, so if you like gore with a plot and plenty of twists, give this one a try.
