While returning home with groceries, Marcia is suddenly ambushed by the man from the previous episode. Later, Tsukasa and Isla are contacted by Souta, who informs them about Marcia's disappearance, and they assume it is the work of a black market retriever. With only 24 hours left on Marcia's lifespan, Tsukasa resolves to retrieve Marcia and return her to Souta, and the rest of Terminal Service No. 1 joins the search. The following day, the office narrows down the search to an area where a black market retrieval service is possibly located, although their efforts are hindered by a unit from R. Security, a private security firm that was hired to assist in the investigation. Kazuki confronts the unit's supervisor, Shinonome, who gives her a map of the area under scrutiny. As the retrievers get ready to converge on the area, Tsukasa is equipped with and learns about a gun-like device designed to forcibly crash all of a Giftia's functions when they turn into Wanderers. He is then approached by Kazuki, who asks him if Isla will be able to handle the situation, but is forced to drop the subject soon afterward. Michiru later tells Tsukasa about how Kazuki tried to retrieve her father when he became a Wanderer, only for him to injure Kazuki and then be shot down by members of R. Security. Soon afterward, the black market retriever is found unconscious and it is concluded that Marcia turned into a Wanderer. Kazuki orders the rest of the retrievers to stop Marcia before she is destroyed by R. Security. Tsukasa and Isla find Marcia, only to realize Souta had been following them. Marcia then injures Isla and kidnaps Souta. Despite Isla's injuries, she and Tsukasa follow her to a rooftop, where Tsukasa nearly manages to convince Marcia to surrender. However, when Souta speaks her name, Marcia snaps and begins strangling him, forcing Tsukasa to pull out his software destruction device and prepare to shoot Marcia. However, Isla suddenly dashes towards Marcia, just as Tsukasa fires the device. The scene then cuts to the Terminal Service office during the next morning, where it is revealed that Isla hasn't signed into the attendance log.
