Komichi Akebi has been accepted into Roubai Academy, the middle school her mother, Yuwa, went to. Komichi has dreamed of wearing a sailor uniform ever since she saw her favorite idol, Miki Fukumoto, wearing one. She puts on the brand-new sailor uniform Yuwa made for her and, at last, heads off to her entrance ceremony. She starts out full of hope that she can make lots of new friends, but then she notices that all the other students are wearing blazers. It turns out the school's official uniform has changed from a sailor uniform to a blazer...

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. That's to be expected, considering all Komichi did was copy Miki Fukumoto's poses. So as Komichi begins to wonder just what her "image" is, a certain occurrence results in her and Kei paying a visit to the Mangetsu Dorm, where Touko and many of their other classmates live. Komichi is deeply impressed by the sweets Touko makes, so with Touko's guidance, she tries to make some of her own...

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. But then one mistaken thought by Komichi changes her day-to-day life: "I want to hear a real guitar! Please let me hear you play sometime!"

Midterm exams are finally over, leaving some students overjoyed and others depressed, and now it's time to decide who will participate in which events at the school's upcoming athletic festival. Riri is selected as the anchor for the swimming event, but Erika nominates Komichi for the same position, so the two girls compete to determine who will be the anchor. Riri is a member of the swimming club, and once made it to nationals in elementary school, and Komichi feels no desire to compete against her as rivals. Then Riri proposes that if she wins, she and Komichi should swap uniforms...

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. When Touko comments that it'd be nice if they could find a place where everyone could practice together, Komichi remembers her previous school, Futaba Elementary.
