In the year 2040, there have been considerable technological advances, especially in city centers like Tonan. One day in late August, Masanobu returned to his hometown after being away in Tokyo for about 3 years and transferred into Kujougaoka Gakuen. After meeting Sayaka and getting a short tour of the city, he later joined her club, ☆☆☆ Club (Three Stars Club). Its primary function is to guide tourists and it is pretty well known both within and outside of the school. He got to know Sayaka and fellow club member Hinano well, and his classmate Aina and imouto Konoka also joined the club which became an oasis to him.
