Kejime is a wealthy, but brutally cruel businessman. He wants nothing more than to control and abuse those around him. Among his victims are Satsuki, a homeless girl whom he has crushed into being his loyal sex slave, and his own son, Susumu.
Susumu, seeking to lead his own life free from his father's control, is studying for his college exams. Kejime, who sees him as little more than his own possession, wants him to go directly into his business and despises the idea of him going to college.
Seeking to help her master, Satsuki devises a proposition. Susumu will be given a series of ten tests. If he passes them, he will be free to go to college and live his own life. If he fails any of them, Susumu will give up on his ambitions and work in his father's company. However, Satsuki is doing everything in her power to rig the tests against him.
Susumu's only allies are two of his fathers maids, Komachi and Nabata, who care for him deeply, and have been the only source of warmth in his life. Will their tutoring be enough to free him from his father's grip?
