You arrive in a small town expecting nothing. By the end, you're watching a girl slowly disappear from existence, and the show has already made you love her too much to look away. Air doesn't explain itself until it's too late, the pacing feels glacial at first, but that's intentional, a slow accumulation of ordinary moments that become unbearable once you understand what they actually mean. The animation doesn't just look beautiful; it's doing the emotional work, rendering every expression, every empty sky, every quiet afternoon with such precision that when the supernatural finally breaks through, it shatters something in you that was built entirely from stillness. By the time you understand what the Winged Maiden actually is, the show has already made you complicit in something devastating.

Yukito Kunisaki is a traveler who earns money putting on puppet shows while searching for the Winged Maiden, a girl from a legend his family has passed down, who was bound to the sky centuries ago. His wandering brings him to a small seaside town where he expects to stay only briefly. Then he meets Misuzu, an unusual girl who seems keen to be his friend, and she invites him to stay with her. As he settles in, Yukito befriends the locals, learns about their troubles and sets his search aside to help them. As his attachment to Misuzu and the town grows, a story spanning a thousand years begins to surface. The show is a supernatural romance drama with a slice-of-life feel, adapted from a Key visual novel.
