Centuries ago, Kanna, a princess and the last of a winged race, was held prisoner in a castle as she was feared by the rest of the world. However, when she met a soldier named Ryuuya, she fell in love with him and told him of her wishes to see the outside world and to find her mother. Ryuuya attempted to fulfill these wishes.

Yukito and Misuzu's fates soon become intertwined with each other, with each developing feelings for the other. However when Yukito realizes Misuzu's connection to the past, he must decide on whether to leave, or to attempt to break the curse that has bound Kanna in centuries of pain.
