The story centers on Tsukasa Mizugaki, a young man who, after failing his college entrance exams, lands a job at the S.A.I. Corporation's Terminal Service. His role is that of a partner to an elite Giftia named Isla, and together they are tasked with the emotionally heavy duty of retrieving androids whose operational lifespan has expired, a process known as "retirement." While Tsukasa is earnest and eager to learn, his new partner is a quiet, clumsy, and somewhat melancholic Giftia who has a reputation for being a veteran but is notoriously bad at her job.
