Confessions aka Kokuhaku (2010). Yuko Moriguchi (Takako Matsu), a junior high teacher, announces she will resign. She reveals that her daughter, Manami, was killed by two pupils in her class, whom she dubs "Student A" and "Student B". Her disclosure of their behavior soon reveals their identities. She admits injecting her dead husband's HIV contaminated blood into the milk cartons that the murderers have just drunk from. The rest of the movie describes the aftermath of this event in a series of first-person narratives from the two students, Moriguchi, and others.
A new enthusiastic teacher is appointed. Student A continues to attend classes but B has developed psychiatric problems. It is revealed that Student A, who planned the murder, did not actually kill Moriguchi's daughter by electrocution; instead she drowned because student B threw her into the pool.
Student B is worried that he will soon die from AIDS and refuses to wash. His mom tries to help but fails. Seeing no hope, she decides to end their lives, but in the ensuing scrap, she is killed by her son, who is captured by the police.
Student A describes how his mother left his family when he was young because she was preoccupied by her scientific research ambitions. He wants to prove himself to her and to earn her attention. His first invention, an electric anti-mugger handbag, earns him a science fair award but fails to make the headlines because of a sensational murder that occurs on the same day. He decides to kill someone so that he can become front page news.
After the incident, student A befriend girl A when they were forced to kiss by the rest of the class. Girl A began to develop feelings for student A, but was murdered by student A out of rage after a heated argument.
At graduation, he plants a bomb in the lecture hall and plans to activate it after his speech, but the bomb goes missing; he then receives a call from Moriguchi telling him she moved the bomb to his mother's office, killing her instead. Moriguchi appears at the end, and tells Student A, overcome and humiliated, that this was her revenge, and that his penitence now begins---but she adds: "Just kidding.", referencing to what student A told her when he confessed that he killed her daughter.
