It takes a great talent and skill to conceal one's talent and skill. Chabashira explains how the system works at this school as the four first-year classes are all ranked by merit, and that class D has the opportunity to be promoted to class C with strong performances on exams. She also warns that with the current situation, anybody who fails one more exam is expelled. Now fully aware of the system, everybody takes their studies more seriously except for the three biggest idiots of the class in Ken Sudo, Kenji Ike, and Haruki Yamauchi. Suzune treats Ayanokoji to an expensive lunch to discuss the strategy, as well as bringing aboard those three to the library to study. Ayanokoji and Kushida succeed in getting them to come, but they leave immediately while Sudo lets everybody know that he wants to make it rich quickly by going pro in basketball That night, Ayanokoji overhears Suzune talking to her brother Manabu, and Manabu attacks her over a disagreement about her view of isolation being independence. Ayanokoji intervenes, and Manabu then reveals that he scored a 50 on every test and asks if it was coincidence or not. The midterm exams come, and class D as a whole performs very well with some scoring among the highest among the first years in the school.
