Heavenly Delusion (Japanese:天国大魔境,Hepburn:Tengoku Daimakyō;lit. 'Heaven GrandMakyō') is a Japanesemanga series written and illustrated byMasakazu Ishiguro. It has been serialized inKodansha'sseinen manga magazineMonthly Afternoon since January 2018 and its chapters have been collected in 12tankōbon volumes as of July 2025.
The manga has two narratives; in one narrative, the charactersMaru andKiruko 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 makeHeavenly 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.
Ananimetelevision series adaptation produced byProduction I.G aired from April to June 2023.
The manga has been received positively, and was praised for its sense of mystery and the relationship between the characters from both scenarios presented at the same time. It has also won several accolades such as theJapan Expo Awards.
Fifteen years after an unprecedented disaster destroyed modern civilization, a group of children live in a facility isolated from the outside world. One day, a girl named Tokio, receives a message that says: "Do you want to go outside of the outside?" Mimihime, another girl who lives in the same facility, has a premonition and tells the upset Tokio two people will come from the outside to save her, one of whom has the same face as her, while the school's director tells Tokio the outside world is Hell. A boy namedMaru, who looks just like Tokio, is traveling through post-apocalyptic Japan with his bodyguard, a girl namedKiruko, in search of Heaven. Maru is looking for a person who has his face, and he and Kiruko often encounter thieves andkaiju-like creatures they call "man-eaters". While Kiruko is a skilled fighter when dealing with enemies, she also mentors Maru who has an unknown power that allows him to instantly destroy the man-eaters. The narrative constantly switches between Heaven and Hell, expanding each side of characters.[2]
Following the conclusion ofAnd Yet the Town Moves,Masakazu Ishiguro spent approximately a year developing a new series.[3] His conceptual framework forHeavenly Delusion drew inspiration from the earlyKojiki period of Japan and explored relationships between humans andartificial intelligence. The initial concept originated in 2013 as cover art for the magazineMonthly Comic Ryū.[4] Ishiguro noted unintentional similarities to his favorite work,Akira, including the post-apocalyptic setting and the dynamic between the protagonists Maru and Kiruko. He consciously emulatedAkira's detailed approach to backgrounds and character mannerisms, such as eating scenes.[5] Deliberately seeking a darker tone than his previous work, Ishiguro aimed to depict "evil" convincingly, resulting in a significantly more grim post-apocalyptic world forHeavenly Delusion.[5]
After Ishiguro drafted character designs for ashōnen demographic, editors fromMonthly Afternoon requested he create a series for theirseinen magazine.[6] The resulting series employed a dark tone centered on children's delusions, a contrast to his earlier work, though Ishiguro still intended it for his existing readers.[7] This theme was exemplified by the character Tokio, who resides in a mysterious facility and collects fantasy paintings created by her friend Kona, a character capable of imagining things he has never seen. Ishiguro related this ability to his own process of "drawing delusions".[7] To preserve the series' mystery, the first volume established numerous plot threads with minimal direct foreshadowing of events.[7]
Ishiguro first conceived the story's premise while a university student, based on a race on a circuit where the Earth is destroyed mid-event and the protagonist faces death. He created an ambiguous title by juxtaposing the words "Heaven" (天国) and "Great Demonic Lair" (大魔境).[8] His artwork for the series became more detailed, particularly in rendering Kiruko's facial expressions.[8] The design of the man-eaters, orkaiju-like creatures fought by Maru and Kiruko, was based on prehistoric organisms such as those from theCambrian period, with their forms adapted to suit Ishiguro's drawing style.[4] Ishiguro's longstanding interest inscience fiction, influenced by the manga duoFujiko Fujio, continued to inform the series' themes.[4]
The manga's development spanned several years. Ishiguro's enjoyment of walking led him to fantasize about a world destroyed by catastrophe, finding inspiration in anime such asArmored Trooper Votoms, whose protagonist Chirico Cuvie wanders alone. This inspired the concept of a solitary hero traveling in combat armor, which influenced the leads' characterization.[6] Initially planning a desert setting, Ishiguro changed to an urban environment after the Minami Kamakura Film Commission released a promotional video featuring a similar desert image with music byKenshi Yonezu.[6] Drawing backgrounds with numerous buildings proved challenging. The concept of the academy was modeled afterYumeno Kyusaku's novelDogura Magura.[6] The series was extended beyond its original planned length after Ishiguro judged the initial ending to be weak, and he frequently revised panels and scripts during production.[6]
The sibling-like dynamic between Maru and Kiruko was based on Ishiguro's personal observation of someone showing interest in his sister, combined with inspiration frombuddy films.[8] Maru's character design was based on Kon fromAnd Yet the Town Moves, inspired by howJoJo's Bizarre Adventure's eighth story arc,JoJolion, reused previous characters.[8] A central narrative premise involves Maru developing feelings for Kiruko without knowing his bodyguard is a man inhabiting a girl's body. Ishiguro described this as "transsexual sci-fi", alluding to the potential for Maru's feelings to persist even after learning the truth.[9]
When Ishiguro started writingHeavenly Delusion, he felt discomfort about events in Japan. Around 2017 and 2018, Japan was looking for flaws in its governance in the run-up to the2020 Summer Olympics. Ishiguro personally experienced a case ofdéjà vu because of the scandal with the empty New Year's food and wanted the handling of meals to be properly shown in his work. At that time, the country also experienced earthquakes and tsunamis. Sensing an ominous similarity between that time and the present, Ishiguro wanted to convey the sense of threat the society increasingly felt. The credo of the series is to be cautious, lest may encounter something truly terrible. The character of Totori was written to prove people who can easily be seen as villains are important to others; Totori is friendly with Maru and Kiruko to the point she attempts to seduce Maru who rejects her. In the aftermath, the duo learn that Totori belongs to a gang who had been chasing them in the past days and died, leaving her all alone.[6] While reading the manga, Ishiguro wanted the reader to experience fear. One the manga's central themes is the most-minimal "heaven" for people is to "feel extremely comfortable in their own field of vision"; if a manga continues this search for "heaven" too much, the place will come across as a "hell". The concept of looking for heaven is the biggest moral of the series.[10]
Ishiguro wanted to tell the story of a girl's body that contains the brain of her younger brother, but he does not remember when the idea came to him. He was inspired by stories of brothers and sisters, so he wanted to create his own story about a brother and a sister swapping places. He rejected coincidences related to magic and wanted to create a more-realistic world to show what might happen after abrain transplant. He opposed the idea of a man turning into a woman, leading to jokes about cleavage and lacking a penis. Instead, with Kiruko, he wanted the scenario to be more realistic. Another theme is a change in relationships in the event of asex change. Ishiguro often writes metaphorical situations; Kiruko's menstrual cycle is caused by a clash with Maru's lips when awakening from a hallucination from a Hiruko's attack.[6] Kiruko represents a gradation of spiritual sexuality. The school is depicted as a kind of thought experiment in a world where sexual elements are abolished.[4]
In the bookCritical Posthumanities, Maru and Kiruko are called posthuman characters based on the commentaries from Francesca Fernando; Maru possesses an outstanding physical shape that allows to fight older people all alone and easily recover from wounds that do not work on common people like regrowing a tooth he loses when being attacked. As the series progresses, it is revealed Maru is one of the first humans born with the nature to eliminate Hirukos just like him. The apparent lack morals Kiruko and Maru display in the series were noted for being allowed a woman to let a man-eater confused that might be her late son living as a man-eater. Maru's design includes a black jacket that contains "We are neither machines nor game pieces". This comes across as a visual resistance throughout the series against the non-consensual corruption of the children who suffer traumas while dealing with their supernatural abilities given by the doctors from Takahara Academy. Maru and Kiruko also show morals about the possible evolution of man-eaters in the first episodes of the anime but such scene ends with failure when one of them kills a woman claiming to be its mother. Kiruko is seen as a "humanchimera" due to the nature of their life after the surgery. The writer calls Kiruko "a new person born out of the combination of two bodies and yet a separate existence from them".[11]

The reviewer said while the volume explores the mysteries behind Kiruko, there were still too many mysteries the plot would explore in the future.[2] The French websiteManga News called the manga's premise captivating due to the mysteries it shows.[21]Sigue en Serie also commented on the mysteries of the series, which would motivate readers to quickly move to the next volume to understand more of the plot through the parallel storylines.[22] By the third volume,Manga News noted the events on the both storylines had been connected, especially from Tokio's point of view, while the duo's journey was noted to be more comic than tragic as a result of the way Ishiguro writes the chapters.
