The new school term has begun, and Yuu's band has begun to practice in earnest. They have one of their idols, Hisashi of HEDGEHOGS, teaching them how to play their instruments, but bassist Yuu and vocalist/guitarist Fuuka are complete beginners. Nachi isn't much better as a drummer, so their practices are going nowhere. Then they meet a senpai from their school, Sara Iwami. She's cold to them at first, but then something changes her tune...
新学期になり、本格的にバンドの練習を始めた優たち。憧れのHEDGEHOGS（ヘッジホッグス）のヒサシに演奏を教えてもらうことになったものの、ベースの優とギター＆ボーカルの風夏は全くの初心者。キーボードの三笠、ドラムの那智も不慣れで演奏は全くうまくいかない。そんな時、優たちは学校の先輩である石見沙羅と出会う。初めて会った時には冷たい表情で怖そうなイメージの沙羅だったが……!?
