Tooru Minegishi

Kazue Takanashi's ex-husband, Toru, is a man who enjoys extreme forms of self-inflicted pain and humiliation. He isn't ashamed about it and often makes his preference known in public settings. His role as the assistant to Kazue's mother involves monitoring the wellbeing of her siblings and reporting their condition to her, who has a lot on her plate and can't always be present for them.
