Tomoe and Mio treat the protagonist to a special birthday date, starting with a risky shopping trip for swimsuits and culminating in an intense threesome at a hotel. While the protagonist struggles to remind himself that his role as the academy's official gigolo is merely a means to pay off his debts, his celebrations are cut short by the arrival of Student Council President Louisa Richter, who demands the immediate abolishment of the school's secret paramour system.
