It's his first day at SAI Corporation, and Tsukasa Mizugaki is excited. After a recomendation from his father, Tsukasa scores a role in the terminal service department. He is tasked to pair up with Isla, a female 'Giftia' android. Their job is to recover other Giftias that are close to expiring.

Tsukasa and Isla's teamwork hasn't been off to a good start. They are finding themselves failing at the easiest tasks. But who is letting the team down?

Tsukasa and Isla have to handle a delicate case in which an orphaned child has to come to grips with losing the only family he has left – his Giftia.
