The Heavenly Delusion manga by Masakazu Ishiguro is getting a Production I.G-produced TV anime adaptation, which will premiere sometime in 2023.
A teaser visual was released with the anime’s announcement. Ishiguro also uploaded a special illustration.
The manga previously received an animated PV produced by Minakata Laboratory with production assistance from WOW WORLD in 2018. Task Watanabe directed the PV.
Heavenly Delusion began in 2018 and has seven tankoubon volumes as of March 2022. The Kodansha-published series is serialized in Monthly Afternoon and published under the Afternoon KC label. It came in first on the Kono Manga ga Sugoi! 2019 ranking (male category).
Denpa Books describes the plot as:
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.
Maru, with the aid of Kiruko, is out there crisscrossing what was once Tokyo for heaven. But after searching for so long, maybe heaven is more of an untenable dream than a potential reality.
