Doubt is a heartwarming manga centered around the adventures of Yuu Aikawa and his girlfriend Mitsuki, and... Oh, who are we kidding here? Doubt is a horror manga written by Tonogai Yoshiki with enough bloodshed and plot twists to make your head spin. Yuu is just your average teenager who has agreed to meet up to play Rabbit Doubt (which you win by killing a wolf hidden between a group of rabbits) with his friends: Eiji, Hajime, Haruka, and Rei. Along the way, he meets up with his childhood friend Mitsuki, goes to a karaoke bar, and has fun. May or may not have a sequel in Judge.
