A month after the Sledgehammer incident, Iwai has been more on guard about Authors, and the students now move to the third-year in spring. Kiri convinces Yamane to act normally. As a change of pace, Kiri asks her if there was any place she wants to visit with her new found freedom. She mentions her father and his travels...and invites Kiri and friends to a food bar. Meeting the employees: Koizumi Houichi a deaf man, and Karuko Hitomi a blind woman with a white piano. Kiri took a step outside to meet Seigi Nakajima an Author with his Killing Good "The Rulebook of Sentencing and Execution" summoning a hanged rope. Before taking action, a police officer Kozakura Zenigata intervenes as Nakajima briefly hangs her to his escape. Later, after the unconscious Kozakura wakes up, Kiri and the By?inzaka sisters discuss about Nakajima. In the end, it is revealed Karuko's piano is the Killing Good "Pianissimo of Ecstatic Symphony" and Koizumi is her Instead.
