Two parallel worlds collide in a grim, post-apocalyptic search for heaven
In short: In a world ravaged by an unprecedented disaster, two stories unfold simultaneously. One follows Maru and Kiruko through a wasteland filled with man-eaters, while the other tracks children isolated within the walls of Takahara Academy. As these narratives intertwine, the line between a sanctuary and a hellish delusion begins to blur.
Written by Masakazu Ishiguro and serialized in Monthly Afternoon since January 2018, Heavenly Delusion is a seinen manga that explores complex themes of gender, natural disasters, and the intersection of humanity and artificial intelligence. The series is structured around two distinct timelines: a post-apocalyptic journey through Japan and the isolated existence of students at Takahara Academy. As the story progresses, it is revealed that the academy's timeline actually takes place several years in the past, serving as a precursor to the world Maru and Kiruko inhabit.
The narrative is driven by profound identity shifts and biological mysteries. A central element involves Kiruko, a skilled fighter who is revealed to be a man whose brain was transferred into his fatally wounded sister's body. This 'transsexual sci-fi' concept explores how relationships might evolve following such a transformation. Meanwhile, the duo faces 'Man-eaters'—kaiju-like creatures whose designs were inspired by prehistoric organisms from the Cambrian period.
Ishiguro's work is deeply influenced by his personal observations of Japanese society, specifically the sense of threat felt during the earthquakes and tsunamis of the late 2010s, as well as political scandals. By juxtaposing 'Heaven' with 'Great Demonic Lair,' the series poses a philosophical question: if a search for comfort becomes too narrow, does the destination transform from a paradise into a hell? The series has gained significant popularity, with over two million copies in circulation by July 2025.
