The days leading up to the end-of-year class party are characterized by the students' frantic and expensive preparations for the event. Janu engages in a strange, reflective interaction with his other half, Juna, while they wait for her train. During this time, they play a game where they describe classmates in single sentences, revealing their shared, cynical, and deeply perverted perspective toward the girls in their lives. Juna urges Janu to attend the party, predicting that his presence might lead to "getting lucky."
Meanwhile, Tuli and Eruka act as self-appointed, high-handed disciplinarians tasked with beautifying Nirima, Nokana, and Oki for the event. Their process is absurd and degrading, involving a riding crop to punish the students for speaking out of turn and bizarre quizzes on basic beauty products. The session culminates in chaos when Sora arrives to enforce the beautification process, further frustrating Nirima. Janu eventually departs for the venue, reflecting on his complex feelings toward his students and the impending conclusion of their time together.
