There are a number of flashbacks that Yukito has of his mother telling him about the girl with wings, about how she will forget everything and die when she dreams her final dream, and about how the person close to her will also die. Misuzu's foster mother leaves, leaving Yukito and Misuzu alone. Misuzu tells Yukito about her last dream, and Yukito comes to the decision to stay by her side, knowing the consequences. Yukito suddenly disappears and after Misuzu wakes up feeling better, she wonders where Yukito has gone or if he will come back.

This story takes place 1000 years before the Dream arc. Kanna is a girl with wings confined to a palace with a friend, Uraha, and body guard, Ryūya.
