Yorito Morimiya is a young boy who loves taking pictures of the sky, and one day in the early morning while setting up to take a snapshot of the sunrise, he meets a strange girl. After talking with her for a few minutes, she disappears and is no where to be found. The next day, Yorito is coming back from buying some groceries on a rainy night and runs into the same girl; this time he finds out her name to be Matsuri Shihō. Later on, Yorito figures out Matsuri lives in a church and goes to find her. At the same time, Matsuri is being hunted by a mysterious man.

Matsuri tries to forcefully stab Aono with her sword, but Aono moves out of the way in time; she still manages to get a wound on her shoulder. While Aono runs away, Yorito is left with an arm missing and he slowly becomes weaker since Aono is losing her Yaka powers. Matsuri tells Yorito to not intervene and goes after Aono. During the fight, Matsuri loses her sword, and Aono takes it up to shove it into Matsuri, but Yorito, not listening to Matsuri's heeding words, intervenes and he is impaled on the sword. Yorito then disappears in a flurry of paper followed by Aono's shrill cries. Matsuri does not hesitate this time to stab Aono and after the sun rises, Matsuri also disappears, but Aono is now human. One year later Aono comes back, and no one but she herself remembers who she is, or any of the incidents that happened. Aono meets with Mana and Koyori and they become friends again.
