Heavenly Delusion (Japanese: 天国大魔境, Hepburn: Tengoku Daimakyō, lit. 'Heaven Grand Makyō') is a Japanese manga series written and illustrated by Masakazu Ishiguro. It has been serialized in Kodansha's seinen manga magazine Monthly Afternoon since January 2018 and its chapters have been published in ten tankōbon volumes as of February 2024.
The manga has two narratives; in one narrative, the characters Maru and Kiruko travel across a post-apocalyptic world to reach an area called "Heaven"; in the other, a group of children live in a school their superiors call "Heaven". The series was inspired by a manga Ishiguro read in university; he intended to make Heavenly Delusion different from his previous work, And Yet the Town Moves, portraying a proper dynamic between the two leads and the evil they face. Heavenly Delusion has themes of gender and natural disasters, which were inspired by Ishiguro's personal feelings.
An anime television series adaptation produced by Production I.G aired from April to June 2023.
The manga has been positively received positively, and was praised for its sense of mystery and the relationship between the characters.
