Synopsis: The story is set in the rural town of Toki Island City, near the sea. The protagonist, Aoi Ogawa, lives an ordinary life as usual. In the midst of this ordinary scenery stands a towering skyscraper known as the "Tree." Thirty years ago, it suddenly appeared, causing a nationwide commotion, but now it has become nothing more than a desolate tourist attraction. Meanwhile, Aoi's science club has been decided to be disbanded. The members set out on the day before its disbandment, July 29, to observe the "Tree." On that day, at that time, in that moment... The "Tree" begins to sing, and... July 29th starts looping.
