Satsuki, who remarried the father, came to live in the house a few months ago. Their son Ittetsu has harbored hatred toward “mothers” since separating from his mother 15 years ago, and even though Satsuki tried to fit in, he refused to speak to her. One day a woman visits Ittetsu. Unaware, Satsuki receives a letter from that woman — who turns out to be Ittetsu’s mother, Chisato. Unable to accept the two mothers who suddenly appeared, Ittetsu proceeds to sexually assault and rape them, treating them as lewd women.
