Kei, who joined the photography club, asks Komichi to model for some photos. They get started right away, but Kei says the photos don't match the image she has of Komichi.

As classes end and students are heading to their clubs, Hebimori Oshizu, who didn't join any clubs, returns to her dorm alone. She's interested in music and bands, but the rock music playing through her headphones and the music magazines featuring her favorite artists are enough for her.

One day, in the midst of practices for the athletic festival, Erika finds out that Komichi is going to dance at the festival's after-party. She starts to imagine what would happen if she played the piano accompaniment for Komichi's dance, but she keeps it to herself. Meanwhile, Komichi is practicing hard at volleyball, but despite the fact that it's a major team event, their teamwork is somewhat lacking.
