The new semester of Sakuragaoka High School has begun, which not only means that many new faces will appear on campus, but also means that a vigorous club recruitment war is about to begin. The innocent girl Hirasawa Yui (voiced by Toyosaki Aoi) has a vision of new campus life but is also worried. At this time, a carefree girl Tian Zhongli (voiced by Sato Satomi) appeared in front of her. Under the enthusiastic invitation of Ali, the somewhat slow Xiao Wei inexplicably became the guitarist of the "Light Music Club". Xiao Wei, who came to the activity room of the Light Music Club, met the bassist Akiyama Mio (voiced by Hikasa Yoko). This somewhat serious but somewhat shy black long straight made Xiao Wei feel good. But then Xiao Wei discovered that all the clubs in this legendary light music club were actually the three of them, and according to the school regulations, any club with less than four people would be disbanded. What to do? Xiao Wei, who had just joined the club, immediately had to start fighting to ensure that the club would not be disbanded!
