Killy is a man of few words. He wanders, seemingly endlessly, through a lonely, gargantuan labyrinth of concrete and steel, fighting off cyborgs and other futuristic nightmares, searching only for something called Net Terminal Genes. And he has a very powerful gun, which he uses without hesitation whenever anything resembling danger rears its ugly head.

Who is this quiet, violent, determined man and what are these Genes he seeks? The small communities he finds tucked into the crevices of this towering, dystopic ruin hardly give him leads on his treasure, driving him to find larger enclaves of civilization where people can reveal more about the world he lives in and the quarry he seeks.

Outer space, the far future.

A lone seed ship, the Sidonia, plies the void, ten centuries since the obliteration of the solar system. The massive, nearly indestructible, yet barely sentient alien life forms that destroyed humanity’s home world continue to pose an existential threat.

Nagate Tanikaze has only known life in the vessel’s bowels deep below the sparkling strata where humans have achieved photosynthesis and new genders. Not long after he emerges from the Underground, however, the youth is bequeathed a treasured legacy by the spaceship’s coolheaded female captain.

A bloody war that spans millenniums. Two soldiers set out to kill each other. An encounter that could change their two species’ fate forever.

Tsutomu Nihei returns with another addictive manga (see BLAME!), set in the not-so-distant future (3005 A.D.). It follows a character by the name of Kanoe Zouichi and the mysterious Kanoe Fuyu whose luminous form is integrated into the system of his bike. They are agents sent by a powerful organization to retrieve the human with the ability to resist and transmute the NS5 infection that is spreading across the world, named Yion/Ion Green.

However, their mission is delayed by the reckless actions of the Public Health Department's taskforce and the kidnapping of Yion/Ion Green. Will they complete their mission? Where has Yion/Ion Green been taken? These questions will only be answered as more volumes are released.

The art in BioMega is similar to BLAME!, with its complicated concrete sprawl and ludicrously wide, empty spaces. However, things seem to happen at a more reasonable pace. In this manga, there is emphasis on the swiftness of the attacks made by Zouichi, such as the gun being sheathed just before the enemies fall to the ground. Speed is crucial in this manga, unlike in BLAME!, and the plot develops just as quickly. An interesting read, especially if one has enjoyed BLAME!

[From Kotonoha]:

While it’s not explicitly mentioned in the story, it’s believed that Suzumega is at least somewhat related to Abara since it features the Gaunas.

Abara is set in a dystopian world, filled with large structures. The story revolves around creatures known as Gaunas, those who can shape bone like armor and weaponry around themselves by transforming. The transformation begins around the spine and then shapes layered armor. The story focuses on one such Gauna known as Kudou Denji, though he uses Itou Denji as a fake name earlier.
