Bye Bye, Earth

The second season of Bye Bye, Earth . Adonis returns, empowered by darkness, as Belle awakens from her slumber — their fates bound by an inescapable destiny.

Five hundred years have passed since the humans went extinct at the hands of the fearsome and mysterious ‘Beasts’. The surviving races now make their homes up on floating islands in the sky, out of reach of all but the most mobile of Beasts. Only a small group of young girls, the Leprechauns, can wield the ancient weapons needed to fend off invasions from these creatures. Into the girls’ unstable and fleeting lives, where a call to certain death could come at any moment, enters an unlikely character: a young man who lost everything in his final battle five hundred years ago, the last living human awakened from a long, icy slumber. Unable to fight any longer, Willem becomes the father that the girls never had, caring for and nurturing them even as he struggles to come to terms with his new life, in which he feels the pain of helplessly waiting for his loved ones to return home from battle that his ‘Daughter’ once felt for him so long ago. Together, Willem and the girls gradually come to understand what family means and what is truly worth protecting.

For years, declining birth rates have forced what's left of the human race to cede more and more territory to other beings who have appeared to take advantage of the emptying ecological niche. Now, only a handful of humans remain among the remnants of civilization and Earth is dominated by faeries —tiny, ten-inch tall creatures of surprising intelligence. But humanity's importance isn't over quite yet, as young Watashi learns as she makes the decision to return to her hometown and assume her grandfather's position as an arbitrator between the races. Unfortunately, the job isn't going to be anywhere near as simple as she expected, and it's going to take a wisdom far beyond her years to achieve her most important mission.

"Yukio... I'm going to make a friend." A shy boy named Tetsuo. The only thing he had was a giant robot named Yukio. They became "saviors" in the fight against the galactic monsters coming from outer space. After the final battle, Tetsuo returns to Earth for the first time in ten years and witnesses an astonishing world. It's a frozen Earth (named Snowball Earth), where the entire land is covered in snow and ice, being turned into a deadly world! What happened to the human race? And will Tetsuo be able to fulfill the promise he made to Yukio?
