Air Movie Air: The Motion Picture
"The days which are wrapped in the scene of summer pass gently by. An encounter with the girls repeated in the sunlight. Summer continues. She is waiting in the air."
A long time ago, a winged maiden was held prisoner in a castle — cursed never to experience love, lest she die. Centuries later, in a sleepy coastal town, a young girl relives this agony.
