In this stadium of stars once used to heal the hearts of the people that gazed within it, he meets a lone girl - or rather, a run-down robot - Yumemi. Begged by Yumemi to fix the broken projector, he forgets time and works on the repairs, and the rain continues to fall. As their days together slowly drift by, a sense of far-off nostalgia sways the boy’s heart. What is he thinking under this man-made sky? And what is the fate of Yumemi?

Yumemi Hoshino

Voice Actor: Keiko Suzuki

A companion robot mass-marketed before the Great War. Made to look like a 15-16 year-old girl, it’s difficult to tell she’s not human at first glance. Assigned to a planetarium in a department store, she used to man the projector and give commentary. Although once a chatty robot loved by customers and staff alike, she now has bugs in her basic software.

Kuzuya

A man who makes his living selling precious resources that he recovers from towns that were reduced to ruins in the great war thirty years ago, a war that devastated the earth. One day, he infiltrates the Sealed City looking for new treasures and resources.
