Sacrificial Mother (Yojouhan Shobou)

A reputation-obsessed mother, Yurie, allows her son’s blackmailing bullies into their home after they catch him shoplifting, desperately clinging to a facade of hospitality as their groping escalates into systematic sexual coercion. Forced to endure relentless degradation and assault in the family bedroom while her son Ayumu watches in silent horror, Yurie suffers a complete psychological collapse, her pleas and attempts to appease the boys only met with laughter and further brutality. The gang remains in total control, turning her body into a target for ritualized abuse as Ayumu realizes what is happening, and they cruelly ignore her desperate pleas to spare him from witnessing her destruction.
