The school is making preparations for the sports festival, and Rin is inspired to 'do her best' towards the day. Aoki and Hoin use faux intimidation to fire up the kids, although it doesn't go as planned on Aoki's part. Hoin comes up with the idea of a costume parade for the teachers, which Shirai is totally against until Kuro gets excited about her dressing up. On the day of the sports festival, Rin is suffering from a chest cough from working on a banner late into the night. She declines Kuro's offer of taking her to the nurses, stating that she wanted to work hard for Aoki as thanks for seeing through the mess that she is. Kuro is upset to find Shirai had dressed up as a panda, but Shirai hugs her to calm her down, going against her beliefs of skinship. Mimi laments that she misses her father's comfort, and when her mother arrives to cheer on her brother instead, she breaks down and cries. Rin manages to win the relay race for her class, but later that night her cough is still bothering her.
