Disclaimer: I rate manga relative to others so 50 is average 60 is a little above average etc. My score does not mean that this is a bad manga I quite enjoy it. Heavenly Delusion is a postapocalyptic story told from multiple perspectives. Tokio is one of a group of kids living within a sort of dystopian school cut off from the outside world who one day receives a message asking if he wants to go outside. Maru and Kiruko are two travelers going through the postapocalyptic landscape outside fending off bandits and maneating monsters with a strange gun while in search of Heaven. The story follows both groups as it slowly unspools the mystery of the world. Heavenly Delusion is in a similar vein to other SoL/mystery stories such as Kowloon Generic Romance being mostly characterfocused and slowly revealing parts of the mystery. Combined with the mix of perspectives with the series sometimes briefly following minor characters as well the series is very capably able to flesh out the world and the mystery while making the characters interesting and having even throwaway characters play a role in worldbuilding. The use of multiple perspectives proves to work really well once the story gets past the exposition and sets the series apart from other postapocalyptic stories. As far as characters go Heavenly Delusion has a fairly strong cast. Maru and Kiruko who are the main focus of the series both feel childish while still having the grit to survive in a hostile world. Watching Maru grow a bit over time has been a highlight of the manga and Kiruko slowly settling from the role of hired gun into a sort of guardian figure while still pursuing her own goals has been well done as well. The kids in the school have tied really well into the mystery though they arent particularly standout and there are some sexual scenes involving them early on in the series. Though the scenes later tie into the overall mystery and arent just fanservice they are present in the series so heads up I suppose. Minor characters tend to fall into the typical postapocalyptic tropes the bandits the scavengers etc but those living in towns feel full of life and lend a lot to the atmosphere. The overall atmosphere and worldbuilding throughout Heavenly Delusion is absolutely stellar. The postapocalyptic world feels livedin and the people have created interesting systems of survival and towns. New locations are quickly fleshed out often through mostly SoL chapters and overall theres almost as much to find in the atmosphere and settings as in the plot itself. As for the plot well it does a great job slowly peeling back the curtain on a series of mysteries through following Maru/Kiruko and the kids from the school while still going off on little tangents to explore the world more. The pacing is fine as the story doesnt really start to tackle mysteries for a couple volumes and as such has time to flesh out the world and characters a bit before trying to introduce new aspects but then tosses little nuggets of information pretty frequently. Theres not much I can say about the story without spoilers but the reveals are interesting dont feel out of place and overall are quite well done. If you dislike a slower pace you may take issue with it but the series has thus far struck a good balance between reveals and general worldbuilding and I hope to see that continue. There are times where plot threads have been left open which I hope will be addressed in the future but thats my only real complaint with the pacing. Recently the series has been a bit scattered but again I have hope that itll right itself in the future. The art is fine. Theres a lot of white space sometimes and detail is hit or miss but the art does a capable job and the times when it goes from pretty clean to more detailed tie neatly into the atmosphere. Backgrounds the ManEaters and characters often have solid visually interesting designs and composition and paneling are solid particularly for fight scenes which are often abrupt exchanges rather than trying to be more than a simple brawl. The artstyle works really well to enhance the world and the result is that settings and characters have a lot of impact. Overall Heavenly Delusion is a solid postapocalyptic mystery. With great use of different perspectives a fleshedout world and solid characters its a standout series. I havent yet started watching the anime so I cant say how the manga compares but the manga stands strong on its own and is well worth the read.
