RahXephon - S1E10

Sonata of Recollection

Kunugi takes the day off. Quon visits him and plays some music for him, but its incomplete. She goes a little crazy because the song doesn't have an end. Meanwhile, Kunugi goes on a ship for a birthday date, talking to his former wife. She says that he didn't spend enough time with his daughter, using work as an excuse. She gives him the last part of the music. His daughter wrote the music for him. It's her birthday, but she's dead. He visits her grave. Quon finishes the song.
