In the near future, humans live alongside sentient androids called Giftias. However, there is a catch. The lifespan of a Giftia is determined beforehand, and a Giftia can only live for a maximum of 81,920 hours (roughly nine years and four months). If they pass their expiration date, it causes personality disintegration, memory loss, and outbreaks of violence.
As a result, the Terminal Services are established with the duty of retrieving Giftias who are close to the end of their lifespans from their owners, and erasing the Giftias' memories. Follow the work and life of such a team in SAI Corp's Terminal Service One office, the human protagonist Tsukasa and a Giftia named Isla. Slowly, their relationship progresses, and as both slowly fall in love, Isla is revealed to be nearing the end of her own lifespan.
