kimiyoshi haruko

Kimiyoshi Haruko is the mother of Kimiyoshi Natsumi and the wife of Kimiyoshi Tōji. She initially appears as the antagonist in the Onisarashi-hen arc, but it is later revealed that she is innocent. One day, after coming home from school, Natsumi witnesses her grandmother being attacked by Haruko. Eventually, the grandmother dies. Haruko suggests cutting the body into smaller pieces to hide it better. Later, when the police discover the body (as reported on the news), Haruko beats her husband for not hiding it properly. After she leaves the room, he tells Natsumi to call the police, but Haruko overhears this, returns, and stabs him. She then decides she must kill Natsumi as well. Akira calls Natsumi's home and hears her screaming for help. When he arrives, Haruko knocks him out with a vase, but she is subsequently killed by Natsumi. It is later revealed that all of this was a delusion caused by trauma, and that Natsumi was actually the one who killed everyone, with Haruko presumably being innocent.
