Two new amnesiac teenagers arrive in the Quindecim for another game. This game chosen involves ten pin bowling. The balls contain each other's hearts, which each pulse according to its owner's feelings. As the game goes on the two become friendly and begin to recall portions of their memories. The boy recalls that he is a college student named Shigeru Miura and the girl recalls that she was a girl named Chisato Miyazaki who was once childhood friends with Shigeru before moving away. Shigeru then remembers both he and Chisato died whilst on a bus together, while Chisato also recalls more of the truth about herself. After winning the match, Shigeru asks Chisato for a short date together with what time they have left. They part ways at the elevators, happy to have had a chance to spend time with one another. It is then revealed that Chisato was actually Shigeru's other childhood friend, Mai Takada, who underwent plastic surgery to look like Chisato in order to catch Shigeru's eye. They are both sent to be reincarnated.
