Sora no Method  

Celestial Method, sorameso, 천체의 메소드, 天体のメソッド

Seven years ago, there was an unidentified flying object that appeared mysteriously in Kiriya Lake's sky. This event caused widespread fear and uncertainty among the townspeople as no one knew what it was or where it came from. Over time, however, this occurrence became a popular tourist attraction. Eventually, people lost interest entirely, and the saucer remained largely forgotten. Now, after living in Tokyo for seven years, Nonoka Komiya returns to Kiriya Lake. Although her memory of her time in the town is hazy, the sighting of a lively girl named Noel triggers memories of wishes that she and four friends made in an old observatory.
