Godzilla 1: Kaijuu Wakusei

Driven from Earth by Godzilla, humanity's survivors have spent years searching space without finding another home. Haruo, who lost his parents during the catastrophe, refuses to accept exile as their final fate and pushes for a return.

By the time their ship reaches Earth, thousands of years have passed on the planet. Strange forests cover a world still dominated by Godzilla, and Haruo joins the expedition descending into it. Reclaiming humanity's birthplace means confronting both an unrecognizable environment and the creature that forced them to abandon it.
