[J Movie] Harmful Insect

Synopsis Sachiko is a 13-year-old junior high school student with a complicated family life. Her father left when she was an infant for a young mistress. Her mother (Ryo) -- a secretive and weirdly distanced woman -- works as a hostess and a kept woman for a mysterious gangster type. Sachiko finds some modicum of solace in the arms of her sixth grade teacher, Ogata who has a brief affair with her. As a result, he quits his job and starts working for a nuclear power plant far away. When her mother makes another halfhearted attempt at suicide, Sachiko's shattered emotional life becomes too much to bear and she drops out of school. Though she continues to correspond with Ogata, Sachiko is desperately lonely and alienated, leading to her consorting with other social dropouts. When her sole school friend Natsuko urges her to return to school, Sachiko finds that her long simmering rage against the world becomes difficult to control.
