In a world where there was a slight advancement in science. After failing his college entrance exams, 18 year-old Tsukasa Mizugaki is offered a position at the renowned SAI Corporation due to his father's connections. SAI Corporation is known for its production and management of androids that possess human emotions called “Giftia.” Tsukasa's position is in the Terminal Service Department where their main job is to recover Giftias that are close to their expiration—it is a graveyard department in every sense. To make matters worse, Tsukasa is ordered to work with Isla, a female Giftia who was never given any responsibility other than serving tea to her co-workers.
