Episode Title:
A Binding... Hard Study.
Episode Description:
After scoring dreadfully low score on her math midterm exam, Rikka is told by Nanase that she is faced with her club being disbanded if she fails the math semester exam. With Rikka not taking her studies seriously, it is revealed that Sanae is the top student in her grade. Rikka tries to improve the club's status by volunteering to clean the pool. However, it backfires due to horseplay for three hours. Instead, Nanase informs Rikka that she will need to make the class average in order to keep the club. Yūta attempts to help Rikka study in her bedroom, but she keeps getting distracted. During a break, Yūta and Rikka exchange email addresses. Yūta offers to come up with a new email address for Rikka should she pass her test, using various bribes each day for a week to get her to study hard. After the math semester exam, Rikka ends up scoring relatively low, but manages to land just above the class average, so Yūta awards her with a new email address.
