This movie sounds awesome. Kami-sama no Iu Toori is based on an anime of the same name and the premise is great!
The story of the original horror-survival manga begins when strange and frightening things start happening at Shun Takahata's high school. After his teacher is killed, he and his classmates must play horrifying games in order to avoid death. The film will also feature two new "games" not featured in the original work: The fifth game, "I hate liars," which is lead by a polar bear, and the fourth game, "Can you play 'kick the can'?," which is lead by a Russian nesting doll.
Not only do I want to read the manga now, but I definitely want to see this movie.
