Killy is a wanderer in a vast technological wasteland known as the Megastructure. His mission is to find a human with net terminal genes to prevent the collapse of the Netsphere, a virtual realm under control of the Authority. His long, desolate journeys are punctuated by brutal encounters with silicon creatures bent on annihilating humanity; cyborgs intent on infiltrating the Netsphere; and the builders, massive machines that mindlessly add to the chaos of the Megastructure. His only protection is an incredibly powerful gun known as a gravitational beam emitter, which he never hesitates to unleash on his enemies. Will Killy be able to find net terminal genes amidst the scattered human tribes, or is the Netsphere doomed to failure?
A girl suddenly finds herself in a room with an identical copy of herself; writing on their foreheads identifies them as 328 and 329. Although there's water, there's no food and all of the furniture is sized for an adult. A raft sits atop a freezing river, but it can only hold one of them. Meanwhile, a buzzing, huge insect tells a chilling tale: only one of them can take the raft to the next world, and must kill the other to do so...
Both BLAME! and White Rain involve mysterious locations that are explored by the protagonists. Mystery also shrouds the characters and what they are attempting to achieve, even though in both instances hints are offered. Both manga offer non-traditional narratives and distinctive art styles.
Both "Hakuu" and "BLAME!" are about people being thrown into strange, grim worlds. The characters are flat, but it almost feels like they're supposed to be like that. The artwork is sketchy and raw, and there is no screentone. While "Hakuu" is the more psychological and thought-provoking of the two, both are abstract manga which deserve a read, even for nothing other than the experience.
In the aftermath of WWIII Tokyo was re-built as Neo-Tokyo; thirty-eight years later it has become a major metropolis. With the memory of the war and reconstruction fading, corruption, criminality and civil strife are threatening to tear the city apart. The military has a secret project developing humans with psychic powers which they hope will help Neo-Tokyo solve its problems. However, when one of the test subjects escapes and hides with one of the biker gangs plaguing the city, the military does everything it can to recover its test subject and cover up the existence of its research program...
Both series have a similar aesthetic and cyberpunk feel to them. Often the managaka will cut away to breathtaking scenery of crumbling, futuristic cityscapes. Both explore similar themes--what defines humanity, and what does technology do to society, but take them in completely different directions, making both an interesting contrast to each other, while still reminiscent of one another.
In the future, the N5S infection is slowly spreading throughout the world, turning everyone it contacts into a zombie-like "Drone". Zouichi Kanoe and his motorcycle AI companion Fuyu Kanoe are sent out by Toha Heavy Industries in order to find humans resistant to infection and save humanity. Competing bio-enhanced agents from the Data Recovery Foundation have different goals, however: how to best extort the situation for their own profit…
As both manga are written by Tsutomu Nihei, they share many obvious similiarties - such as the highly detailed, dark, ominous art style. Both manga take place far in the future and involve strange technologies and massive, deserted superstructures where control has long since fallen out of human hands. The adventures bring the main characters through the slowly decaying remains of humanity's greatness, the child of a futuristic dystopia and an endless haunted house.
With technology so advanced, there are less humans than there are "trans"-humans - either genetically or mechanically enhanced versions of the normal homo-sapien. Both mangas bring a strange sense of slightly disturbed wonder to the reader. That is, wonder at what new situations and creatures await around the next corner, and disturbed as to how wierd, random, and frightning those new things often are.
Perhaps the most defining feature of both manga is the lack of dialogue and obvious plot. Most manga work to give you the plot and have plenty of dialogue to drive the story along - not a bad thing, but certainly the standard. Tsutomu Nihei, however, gives mere clues here and their - even understanding the current goals and motivations of the main characters are difficult. However, this is what makes it so interesting. You are constantly on the hunt for information, searching for any clue, and all the while you are presented with a simply stunning artistic backdrop in which to do so. It is incredibly engaging. Other mangas are read - BLAME! and Biomega are experienced.
Finally, the worlds of Biomega and BLAME! are linked - there are recognizable carryovers and places from each one. The exact nature of that connection is, itself, another engaging mystery to solve, so I'll not ruin your fun with my opinion.
If you just read one of these manga and enjoyed it, I can't recommend the other enough. I am now a huge Tsutomu Nihei fan.
