Akebi Komichi 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, Fukumoto Miki, 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...
