Tengoku Daimakyo - S01

Fifteen years ago, a catastrophe devastated human civilization, leaving dangerous man-eating creatures to roam the ruined world, threatening what little remains of humanity. In this chaos, a secluded facility shelters and raises children in safety. But as some of them begin to learn about the world outside their sheltered home, their curiosity about it grows. Meanwhile, in the wasteland beyond, two young survivors-Maru and Kiruko-travel together in search of a legendary place known as Heaven, each driven by personal reasons. Haunted by past tragedies and hidden sorrows, they hope to find answers to the cruelty they’ve endured, both in their own lives and in the shattered world around them.
