Synopsis

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.

Preliminary (27/? eps)

Tengoku Daimakyou presents us with two sets of characters: a group of orphans in a sterile, mysterious academy (very à la Promised Neverland, as @deadoptimist mentions above), and a two voyagers making their way across post-apocalyptic Japan, searching for this same academy.

Art: Detailed backgrounds and a strong sense of spatiality allow for world building, while characters and action sequences are clean, crisp, and earnest.

Story: Unravels somewhat inconsistently, has a few exposition dump moments. But apart from them, the tension created from the spun web of alternating narratives drew me in.

Characters : what really drew me in, as all the characters feel ...

Mixed Feelings

Well-written

Preliminary (25/? eps)

This manga starts with all the parts necessary for a good postapocalyptic thriller, but fails to develop them in time, while fanservice slowly piles up. The main secret stimulates curiosity though, and robust art makes reading pleasant.

Tengoku Daimakyou conceptually is a polyphonic narrative – each chapter is named after the leading character in it, but in practice there’re two main plotlines. The first is a “Yakusoku no Neverland”-like slow burn mystery inside a very special orphanage, where we follow a group of kids and try to understand what’s brewing. The other is “The Road”-like journey across a calamity-ravaged Japan, riddled with picturesque debris, suspicious ramshackle ... villages, bandits, and occasional monsters. These two parts are obviously connected, the hooks for their meeting are set, but it’s not clear how it will happen in the end – this is the main question of this work, the main attraction of its story.

The second strong point is the art, reminiscent of “Ibara no Ou” or “Apocalypse no Toride”. Tengoku Daimakyou has a similar attractive steady linework and very well-designed debris. It is even, maybe, more cinematographic. The composition of panels, the life-like designs of clothes, buildings and items, the many weathered faces and human types make this manga feel like a modern sci-fi TV movie – enriched with the imaginative freedom of a fully drawn medium and with a strong pedigree of Japanese quirky postapocalypse acutely felt.

The characters also begin in a very promising way. The kids in the shady facility are easily discernible, bright and sympathetic. The slow way in which we catch glimpses of the bigger picture in their simple lives feels natural. The pair of heroes on the road has good chemistry. The dynamic of an older more experienced but somewhat awkward bodyguard lady and a younger, active and capable, but not yet fully grown special boy feels fresh. The two share the childhood of being a post-calamity orphan, so they offer funny opinions on our civilization, now lost for their world.

So far so good, and indeed I couldn’t stop reading for the 10 (very substantial) first chapters or so, but then problems started to become visible. The cracks showed the most in the road story part, with exposition been delayed too much, which harmed characterization. Subsequently the author strained my sense of immersion by swapping genders of several characters in a convoluted way, seemingly largely for shock value and banter jokes. I can’t comment whether it may be interpreted as queer representation, maybe it can, but for me it seems to lack realism, attention, and gracefulness to be a good one or a plus in this story. The narrative is also very clearly male-centric. Only women are sexualized, sometimes in strange ways. The fanservice is light, but it’s all over the place thematically.

And after I had finally made peace with the new data and the new expectations from the characters, another issue arose – and that was the lack of engagement in the road part of the story. As far as post-calamity wastelands go, this one is fairly typical, I am afraid – the ravaged world here doesn’t whoa me by itself. The monsters are rare and there’s too little data on them, likely withheld for the final arc connecting the two plotlines. There’re too many red herrings and inconsequential events, places change way too fast to care, the danger for the main duo stops feeling real. While characters chat plenty, the author keeps readers at a distance from their thoughts and feelings – our connection with them is mostly voyeuristic. Clumsy attempts at unnecessary romance and convoluted sex jokes, increasing in volume with each new chapter, also don’t help.

So, gradually, I found myself not caring about the traveling pair of characters despite the richness of the events which happened to them. The kids’ side still interests me, even if it is oftentimes disturbing. (Speaking about the disturbing part, there’s human experimentation, several suicides, and a bit of body horror – all typical for these types of stories.) And what I am still genuinely curious about is how it all connects. I will definitely come back to Tengoku Daimakyou to check for it.

Overall my rating and personal opinion on Tengoku Daimakyou, based on subjective readability, is not terribly high. But I would recommend this work for its slow-building intrigue. I think it may suit people who like postapocalyptic stories in general. I can gladly advise it for its hearty brisk art. I even think that many others won’t share my problems with the story. However I can’t discard the overly slow exposition, sparse characterization and uncomfortable gender juggling, which disqualify Tengoku Daimakyou for character-focused readers. I have to warn about fanservice, which may put off some people. This is a manga definitely worth trying for yourself, but there’s a non negligible chance of disappointment.

Not Recommended

Preliminary (34/? eps)

Where to start... what I have read is not fan service anymore. It reaches child p-graphy at times. Flabbergasting...

Reading this, you'll also be subjected to this terrible trope of the boy in love with their sister. This is called incest and it is not romantic. Please stop that.

You'll also have to deal with romanticisation of rape. Once again, it is used to advance the story of female characters, while never calling what it is, and not dealing with the trauma it induces.

How can anyone read this and not care at all about these aspects of the story?

Please, stop supporting artists doing ...
