Атрі

Atri is salvaged from the bottom of the ocean by Natsuki.

Despite being a robot, her appearance and her ability to express emotion makes her near-indistinguishable from a normal human being.

It seems like she served as Natsuki's grandmother's assistant in the past, but she has almost no memory of the time before her long sleep beneath the sea. She asks Natsuki for help restoring her lost memories, such that she can fulfill her former master's last order.

Extremely curious and eager to learn, she prides herself on being 'high-performance'.
