Plastic Memories

Tsukasa Mizugaki begins working for a company that creates Giftias, androids with intelligence and personalities almost indistinguishable from humans. Every Giftia, however, has a maximum operating life of roughly nine years and four months. Once that limit is reached, their memories break down, making retrieval necessary before they become dangerous.

Tsukasa joins the department responsible for collecting Giftias from families who may have lived with them for years and is partnered with Isla, a quiet veteran Giftia. Their assignments teach him what it means to ask people to surrender someone they love as family. Then Tsukasa learns that Isla's own remaining time is far shorter than he ever wanted to know.
