- While returning to pick up a notebook at his classroom during nightime, Riki is approached by a girl who urges him to flee. He does as she asks, but after hearing a gunshot, he turns back and finds an abandoned student ID. In the next day, Riki returns the ID to Saya Tokido, a student from the same year as him, and later is invited by her to meet him at the rooftop. When Saya meets Riki, she declares that she must dispose of him, or the "Darkness Executives" may discover her identity. Saya then attempts to have Riki fall from the roof, but when Masato appears, Riki manages to escape by having his friend catch him. Believing it must be another of Kyousuke's pranks, Riki inquires him about the Darkness Executives, and his friend asks him to not involve himself with them, as not even Kyousuke can oppose them for the sake of Rin's safety. After Saya fails to kill him in two other occasions, Riki being saved in the nick of time by Kengo in one of them, she decides to ask for his help instead, revealing that her mission is to locate a "secret treasure" inside the school. The duo then look for clues together when they spot a mysterious contraption inside a classroom, and after Riki figures out how to activate it, a secret entrance is revealed. Riki and Saya then pass through the entrance, fleeing from the Darkness Executives who appear to attack them.
