Bokura no Yoake

In 2038, Yuuma Sawatari is an elementary school kid who loves everything about space and astronomy.

He was initially excited when his parents bought a robot called Nanako, but he was disappointed when he learned that she was basically just a boring housekeeping robot.

However, when he does finally try to talk to her about space, something strange happens.

Her system crashes and is taken over by what claims to be a marooned alien ship!

The alien ship wants Yuuma's help to get back to space!
