Yorito and Aono are planning on leaving so that things will go back to the way they were. Mana tries to get Yorito to tell her who he really is, but he does not say. Later, Mana is out with her friends and she brings up Yorito in conversation, but discovers that everyone else but her has already forgotten about him. Scared of what this means, Mana runs to the school roof and finds Yorito alone. After sunset, however, Mana finds herself alone on the school roof having forgotten about Yorito. Takeshi and Mayuko leave town near the end, and Matsuri goes to Aono's house with Takeshi's sword in hand.
