Ritsu Tainaka wants to reform the light music club which will be disbanded by the end of April if at least four members cannot be found. They put up a poster for the club which catches the eye of Yui and she submits a form to join the club. The three members perform a short piece for Yui; this inspires Yui to finally join the club as a guitarist, though she first not only has to buy one, but learn how to play it first.
