The protagonist, Hoshimi Hikaru, now lives under the same roof with the goddess Mikoto, whom he connected with in the previous story. His long-cherished wish has come true—he now has a cute girlfriend. Miraculous summer days continue. As he spends those laid-back, peaceful days, his ever-free-spirited older sister, Hoshimi Akari, suddenly declares: “Let’s have a wedding ceremony!” Although Mikoto and Hikaru still don’t quite feel the reality of something like a wedding, by spending time together away from home, just the two of them, they begin to slowly envision a future where they will “become husband and wife.” The glittering tale of a shooting star begins once more.
