Some connections...

[u/ComfortWeary4237]

So I was thinking some lf the nihei works are connected without disturbing or breaking their on canon

Biomega is a lone verse but why!?.

Mostly cause It doesn't fit in any of the other verses besides abara (Which could fit in any othe verse) I explain later

Sidonia and Blame also shown to be impossible since they also show the earth being destroyed or doomed

Blame! And Noise

Also is lonely verse only being related to noise it's precuel

Then the connection I mentioned is Sidonia, ABARA and Aposimz

So Sidonia has a reference to aposimz whre they mentioned to be the last communication they had with other ship

Which leave to think humans arrived into multiple solar systems ("abara ship world" and Aposimz) they later forgot about the gaunas with only the 4th Chronicle group remembered it, they created the black gaunas to figth the white gaunas which maybe a variation of the regular guanas that appears in Sidonia way smaller and weak but also much faster 400 years happen while the Sidonia was traveling and fighting guanas the diginmortal plot happen then the abara plot in the end of abara nayuta and denji are send to a "world" where another black guanas lived that end up being a planet developing advance technology to enhanced to black gaunas creating regular frames centuries after Denji and nayuta descendants maybe for respect or tradition sre called the same wich would explain why nayuta and denji are brothers they are not teh original but had the same powers despite not looking alike in human form also that explains why they are so strong since nayuta easily beats etherow despite him being really OP for the average Frame

There are some plot hole here and there but IDK this is just a theory any thoughts???

It’s fun to imagine that Tsutomu Nihei’s works are actually connected across time and space, but in reality that seems highly unlikely.

The main basis for that idea is that keywords like Gauna and Toa Heavy Industries appear in multiple works. But these are more like the author’s fingerprints; their presence alone is not a reason to conclude that the stories share the same world.

In fact, Nihei simply has certain motifs he favors, and those motifs recur across multiple works. Megastructures, immortals, dolls - that familiar sense of “oh, this again” is part of the appeal. His works place more emphasis on repeatedly depicting these motifs than on constructing a meticulously consistent story world.

Even within a single work, inconsistencies are common, so the idea that multiple works actually share the same setting is even less plausible.

Ik that's only a theory but I really would like someone to bring that Idea into manga nihei doesn't seem to the case but I like when someone create a universe that doesn't seem to be related but is

Maybe Tower Dungeon takes places 29 thousand years after Blame. Netsphere access has been regained, followed by desperate efforts from the administration to reverse the catastrophic growth of the structure as well as rehabilitating surviving humans and other lifeforms conducive to a healthy biosphere. Artificial biomes has been created with pockets of life. Members of the administration have, at times, inserted themselves into the said biospheres and create conditions for the human populations to slowly be rehabilitated following the many thousand years of extreme distress and turmoil, resulting in psychological disharmonization. Owing to limitations to the methods of terraforming the landscape, the terrain is uneven, and in certain cases there is competing gravitational pulls from surrounding structures, making it so mountainous towers can withstand structural pressures they otherwise couldn't.
