A blog on a mysterious website quickly spreads like wildfire, starting a dangerous online game. At 3:00 in the afternoon, a teddy bear stuffed with rice and nails is sunk into a bathtub. The lights go out and the player is required to stab the bear with the knife, then write their experiences in the blog. But lately the comments have taken a dark, demented turn, as if the players are being possessed.

Yuri is an ordinary teenage girl. But one day, everything changes when she learns that she's apparently dead. Even though she's technically not alive, she tries to keep her humanity and life. Her family, however, wants her out of the picture.

Higashigaoka Junior High School is in turmoil as one of the pupils, Noguchi, who had been bullied, attempted suicide last term. On the first day of the new term, a substitute teacher arrives to take the second year class. When the teacher, Murauchi (Hiroshi Abe), introduces himself, the pupils are surprised by his stutter. He has a speech impediment. Unable to speak eloquently, Murauchi faces his pupils with ‘words of truth’. His first instruction to the pupils is to return Noguchi’s desk and chair to the original place in the classroom. Every morning Murauchi greets the empty desk, “Good morning, Noguchi.” This causes a ripple beyond the classroom and among other teachers and parents, but Murauchi will not stop doing it. Eventually the day comes when Murauchi must leave.
