Members of the Prefectural Assembly are expected to make an inspection of the school and realizing that it is part of the "final task", Riki and Rin volunteer themselves to guide them around. Despite Rin's shy demeanor, she manages to guide the visitors properly and they later invite her to take part in a student exchange program to help the students of another school overcome a tragedy that claimed the lives of some of their classmates. Riki at first asks Rin to decline their invitation, but he later realizes that this could be an important experience for her to grow as a person. However, when Riki tries to encourage her to take part in the program, she gets angry at him and ultimately accepts the invitation. On the eve of Rin's departure, Riki realizes that all the tasks they received helped her to mature and improve her confidence. He concludes that it was all a part of Kyousuke's plans, including inviting Komari and the other girls to become part of their group. His suspicions are confirmed when Riki finds Lennon with Kyousuke and then he confronts him about the "truth of the world" he mentioned in his letters. However, before getting some answers, they are forced to run away after being caught outdoors during curfew and when Riki trips over, Kyousuke disappears in front of him.
