A giant saucer hangs over an entire city for seven years, and the show doesn't care about explaining it. What matters is the girl who doesn't remember you, the friends you left behind, and the slow realization that you erased something from your own memory on purpose. The story moves quietly, letting small moments of reconnection carry the weight that spectacle never could. By the final episodes, a simple conversation between old friends hits with the force of something you didn't know you needed to see again.

Nonoka Komiya returns to Lake Kiriya City after seven years away, only to find a massive saucer floating over the whole town, where it has hung since shortly after her family moved away. A strange girl named Noel greets her like an old friend, though Nonoka has no memory of ever meeting her. As Nonoka reconnects with childhood friends, pieces of memory begin surfacing, memories pushed down after her mother's death. Something about the saucer, about Noel, and about her last days in town doesn't add up. What happened in Lake Kiriya before Nonoka's family departed? Why does Noel insist they have met? And what part did a group of kids and their wishes play in calling down the object hanging above them all? The result is a gentle fantasy drama about memory, friendship and wishes made long ago.
