Tanukichi wakes up to find Kosuri sleeping next to him and Anna, who had been standing there for hours. He quickly decides to pretend Kosuri is his little sister. Later at school, Anna's father has sent Oboro Tsukimigusa to become the school's prefect. However, unlike the moral authorities, Oboro starts by removing mundane items. She also tries to confiscate Hyouka's yaoi manga until Hyouka convinces her that it has useful value. Meanwhile, Ayame plans to have SOX distribute Otome's drawings at other schools. Kosuri decides to take charge of the operation herself. Later, Kosuri returns to report her mission was completely successful, and fueled by her new success, treats Tanukichi like a slave. While Tanukichi detests her methods, he cannot bring himself to sell Kosuri out to Ayame. The next day, Ayame privately tells Tanukichi that SOX's actions suffered blowback with the sudden appearance of Oboro and her comrades. On top of dealing with the threats of the moral authorities and the Gathered Fabric faction, SOX must also find a way to sabotage the prefect system before the government exports it to other schools.
