After overcoming their disbandment woes, the Meikun High School Social Game Club heads toward summer break.

On Akane’s recommendation, the four of them are slated to participate in a development competition that gathers the best clubs in the country! On top of that, a voice actress who hears of their accomplishments comes along as they pump themselves up for the contest—Yozakura Aina joins the mix. With the five of them, they set out to create a game... or not?! With Kai stuck in a slump and an extraordinary feud between Eru and Aina, development is the last thing on their minds! Will they be able to bring it together and finish a social game?!
