A famous world-class creator is to be chosen as a director for a commercial for macarons, with Mio going to be filming the commercial when they are faced with a surprise. However, the background music is an Ondo, and is not fit for a macaron commercial. It is up to Mio to make an impactful "Big Bang" CM when nothing goes as she had predicted.
Aine Yūki is good at making friends, and is enrolled in Star Harmony Academy's general education track. She befriends Mio Minato, the school's top idol, and becomes an idol herself.
