I came across this manga because I am thinking to watch the movie. The story is incredible dark and disturbing. Suicide in mass... high school students. They are all suffering in some kind of way and decide to enter this creepy society. The opening with the 54 girls jumping in front of the train at Shinjuku station was shocking (although I did watch the trailer of the movie, but in the manga it looks worst in my opinion).
The detective looks exactly the same as the actor. I am still thinking if I should watch the movie or not. The manga was depressing but very interesting at the same time. It will be stuck on my mind.
