Upon returning from Fukushima—a perilous journey undertaken to secure medicine for Kurumi—Hibiki is confronted with the sight of Akiyoshi and Kurumi sharing a kiss. Having failed to obtain the medicine, Hibiki is devastated by the realization that there is no longer any hope of Kurumi regaining her memories. Amidst this turmoil, Tsuboi informs him of a suspicious individual within the shelter, and Hibiki subsequently witnesses Akiyoshi engaging in a dubious radio transmission.
