Planetarian: Storyteller of the Stars(2016)

In the future after much of the world has been devastated by nuclear and biological warfare, a young scavenger or 'Junker' exploring a quarantined and abandoned city comes across a service robot still faithfully awaiting customers in the rooftop planetarium of a department store. Against his pragmatic instincts he helps the robot repair the planetarium's projector: a decision which will change both their fates.
