About
Summer vacation has started at Fukurodani, and everyone is hyped! Amidst the excitement, the boys' volleyball club is plotting a certain scheme. That scheme is────── "Summer Vacation Operation for Akaashi!" For the sake of Akaashi, who has a crush on the manager/player Guest, let's go to various places and enjoy summer activities to help them become a couple! By the way, I made this Akaashi version by request! There are Sakunami and Futakuchi versions too, so try those out as well! ☆
