This movie contains disturbing scenes, as in term of violence, murder, sexual activity. Not that much of gore, but for someone like me who despise gore films, I had to fast forward some scenes... but anyway, the story is brutally touching, making people wonder the true meaning of life...
The cast did a great job, Sato Jiro delivers as usual, and I'm kinda amazed with Ito Aoi's acting. This is the 2nd time I watch her movie, and I thought she has the potential to be a big star. Shimizu Hiroya's acting is good enough to give you chills. Overall this movie is good, but doesn't have a high rewatch value I think.

Also, the last scene is such a tearjerker....the amount of sadness in that scene is just too painful.
[SPOILER] I still can't understand the meaning behind the invisible ping pong...is it to symbolize that they will no longer play ping pong together again in the future? or maybe that's some kind of illusion that they are playing ping pong together? Idk..but the last scene certainly left a big impression...
