The anime is expected to be aired by the end of 2023!

Within the safety of the walls, youths are raised in a nursery-style setting by robots. While life there may appear stale on the surface, the children are full of potential and curiosity. In many ways it is like a slice of heaven. The outside world is a hell-scape. It is almost entirely void of anything mechanical and is now inhabited by bizarre, yet powerful super-natural beings.

Masakazu Ishiguro wrote and illustrated the Japanese manga series Tengoku Daimaky. Since January 2018, it has been serialized in Kodansha's seinen manga magazine Monthly Afternoon. Production I.G is set to release an anime television series adaptation in 2023.
