It has been a week since Matsuri started living with Yorito and he as become visibly suspicious to Mana who wants to find out what he is hiding. Mana comes over one night and tells him that she wants to make him dinner, though after he leaves to buy some seasonings, Mana tries to search the house. While initially unsuccessful, Mana runs into Matsuri eating in the kitchen and they become acquainted.

Yorito finally decides to introduce Matsuri to Aono under the guise of her being his new girlfriend, but when they go to visit Aono, the latter feigns sleep. Later on, Aono meets with Matsuri in a tram depot where it is revealed that Aono is also a Yaka and her powers are now returning. Aono comes home with Matsuri and Aono tells Yorito that she has permission from the hospital to stay at home for now. After dinner, Matsuri and Yorito go to Yorito's school. At the roof of his school, Matsuri explains the loneliness of Yaka to Yorito. After that, Matsuri kisses Yorito and disappears.

He later confirms this after confronting his "sister" about what she is hiding from him, but Aono would not tell him. Yorito and Matsuri meet in the abandoned building where Yorito stabbed Matsuri in episode seven. Yorito asks her why he would have memories of hundreds of years ago, and Matsuri stabs him with Takeshi's sword to show him the truth.
