Komari continues to dream about her brother, who Riki suspects may be already dead. Riki goes to see Kojirō to learn more about Takuya. Kojirō merely tells Riki that he should not pry further into the matter if he cares about Komari. Unable to sleep, Riki goes out to buy a coffee and encounters Komari at the school gate, who had gone out to buy snacks. She invites him up to the school roof to watch a meteor shower, where they spend the rest of the night making wishes. Komari asks Riki to go on a date with her so she can search for her lost memories. They take a train to go to where Komari used to live and they end up taking a boat out on a lake. Riki suggests to her that she does not necessarily have to look for her brother, and Komari jokingly asks him if he will be her brother. It starts raining on their way back towards school, and while running to find shelter, Riki spots a dead kitten. Komari starts sobbing uncontrollably as she recalls memories of her brother.
