At the beginning of the new school year, the light music department of Qiuying Senior High School could not reach the minimum number of four members, because all the original members left the school after graduation. The only new members of the Department of Light Music are Qiu Shanling and Nakata Tadashi.

Gentle and lovely miss playing the piano? I joined the club because I thought the interaction between Tanakalu and Qiu Shanling was very interesting. Hirasawa Yui mistook "light tone" for "light music".

So, there are bassist Qiu Shanling, guitarist Hirasawa Yui, drummer Tajing Taxiong and keyboard player Qin Chui? . Later, Nakano Azusa, a new member, joined the Light Music Department and became the second guitarist.
