The Main plot of Doubt is based on a Game of Survival. A few people who are complete strangers to each other are either randomly or purposefully chosen in a famous Game called RABBIT DOUBT.
Believe me from my Personal experience with this anime that there will be atleast 3 to 4 instances where your Predictions regarding the Story will definitely be Wrong.Thats the greatness of this anime.This is really a breath of fresh air for all the people who read shounen manga all the time.Just give this Manga a try and trust me you wont be disappoined.
Truly a Spine tingling thriller Manga.
A must read,highly recommended by me.
Those who like Death note and Kaiji.will definitely love this.
I think the manga "Judge", which has like 10 chapters out at the moment, is made from the same people who did "Doubt". Both are really good mangas for those looking for a good thriller read. I just hope Judge doesn't follow the same plot and what not of Doubt.
