Biomega Review: A Synthetic Man, a Motorcycle, and a Grizzly Bear With a Rifle

I came to Tsutomu Nihei the way a lot of people do: through Blame!, completely lost, flipping pages of silent corridors and not understanding a single thing — and loving it anyway. So when someone told me there was a Nihei manga with the same crushing architecture and the same wordless dread, but also a talking grizzly bear who carries a sniper rifle, I genuinely thought they were messing with me. They weren't. Biomega is that manga, and the bear is real, and he's wonderful.

I read all six volumes in one long, jet-black weekend. It is the first Nihei book I'd actually hand to a friend who isn't already a Nihei person. It's faster, louder, and just barely more legible than Blame!, and it still looks like nothing else on a manga shelf.

Quick Take

• A synthetic human named Zoichi Kanoe rides a dying, virus-transformed Earth on a motorcycle — its AI, Fuyu, lives inside the bike — hunting the rare humans immune to a plague that turns everyone else into zombie "Drones"
• Tsutomu Nihei's most accessible work: more story than Blame!, same overwhelming architecture and body horror, plus a rifle-wielding talking bear
• 6 volumes, complete in English from VIZ; rated M (Mature) for graphic violence and body horror

Story Overview

It opens with humanity's first manned mission to Mars in seven centuries — and the astronauts find something on that abandoned station that should have stayed buried. What they bring back is N5S, a pathogen that spreads across Earth at terrifying speed and converts ordinary people into Drones: disfigured, zombie-like husks.

Zoichi Kanoe is a synthetic human dispatched by TOA Heavy Industries. His job is to find "Accommodators" — humans who carry N5S but don't turn, instead gaining regeneration and longevity — and recover them before the rival faction does. That rival is the DRF (Data Recovery Foundation), and the early volumes are essentially a brutal extraction mission: Zoichi races to reach a young Accommodator named Eon Green inside a locked-down containment city, fighting through Drones, DRF agents, and the architecture itself.

Then the story does something only Nihei would do. Around the midpoint, the DRF matriarch Niarudi deploys a Reverse Morphic Polymer — a "Recreator" meant to remake the world in her image. The plan slips out of control. The planet is reduced to ruin, and in its place a vast, cord-like new world grows, with its own population and ecosystem. The back half of Biomega takes Zoichi and his allies into that bizarre cord-world, racing toward a final confrontation with Niarudi over what humanity will even become. The time skip is jarring on purpose — the book essentially restarts its own setting.

Characters

Zoichi Kanoe — The synthetic agent at the center. He's quieter than most leads but far more talkative than Blame!'s Killy; he actually has a personality and a mission he states out loud. He doesn't agonize over being synthetic — he simply is what he is, and he rides through the apocalypse doing his job. His arc is less internal than situational: he's the one constant dragged across the planet's total reformatting.

Fuyu Kanoe — Not a sidekick standing next to him — an AI whose luminous form is integrated into Zoichi's motorcycle, feeding him analysis and strategy. She's a presence more than a body for most of the run, which makes her late-story sacrifice land: in the final push, Fuyu gives herself up to get Zoichi past the wall of DRF agents.

Kozlov L. Grebnev — The talking grizzly bear, and the reason half the people who love this book love this book. He's a scientist who transferred his mind into a bear's body to escape N5S; as a bear he walks upright, talks, and operates firearms — including a sniper rifle. He works alongside TOA's Nishu Mizunoe, and in early volumes he's introduced aiming that rifle at Zoichi before they end up on the same side.

Nishu Mizunoe — A fellow synthetic agent in TOA's orbit, paired with Kozlov. She's part of the surviving "Team Kanoe" that pushes through into the new world alongside Zoichi.

Niarudi — The DRF's matriarch and the engine of the whole catastrophe: the one who weaponizes the Recreator to remake the planet. Her ambition is so total it consumes her — by the end her brain is fused into the Recreator's nerve structure, unable to fully control it and unable to detach, slowly absorbed by the very thing she built.

What I Love About It

Kozlov. The bear. I have to lead with the bear, because Nihei could have given Zoichi any partner imaginable and he chose a grizzly with a sniper rifle and a scientist's vocabulary. In almost any other manga that's a joke — a one-page gag. Here it's played dead straight inside one of the bleakest worlds in the medium, and the absurdity never breaks the tone. It sharpens it. A talking bear lining up a headshot over a city full of Drones is somehow more unsettling than if Nihei had played it for laughs, and it tells you everything about how confident this book is.

But underneath the bear, what I really love is how Biomega solves the thing that scares people off Nihei. Blame! asks you to climb its silent megastructures with almost no guidance. Biomega keeps the architecture — the towering, oppressive industrial vistas you read in cold sweat — but gives you a clear engine: a man on a bike, a person to rescue, a faction to beat, a deadline. The visual storytelling is still doing the heavy lifting; whole sequences pass with barely a line of dialogue, just speed and concrete and violence. It's Nihei's imagination at full power with just enough handrail to hold.

Memorable Scene ⚠️ Spoiler Warning

The moment that stuck with me isn't a fight — it's the world ending and then regrowing. When Niarudi triggers the Recreator and it spirals out of her control, the Earth I'd been reading for three volumes is wiped out, and in its place this enormous cord-like world unfurls, complete with its own ecosystem and inhabitants. Nihei doesn't ease you into it. One arc is rubble and Drones; the next, his characters are crawling through an alien new reality that grew over the corpse of the old one.

What makes it haunting is the final image of the architect herself. Niarudi gets exactly what she wanted — control of creation — and it destroys her. Her brain adheres to the Recreator's nerves, but she can't seize full command and she can't pull free, and the thing she made starts absorbing her ego. The mastermind dissolving into her own godlike machine is the most genuinely sci-fi idea in the book, and it's the page I think about when people say Nihei "has no story." He does. He just buries it under a hundred meters of concrete and a grizzly bear.

Pros & Cons

Pros

• Nihei's visual imagination — the architecture, the Drones, the alien cord-world — at full strength
• The most accessible entry point to Nihei: an actual plot, an actual goal
• Six volumes, complete in English, fast-paced
• Kozlov the rifle-wielding bear is one of sci-fi manga's great supporting characters

Cons

• Character interiority is thin; people are vessels for the world more than the reverse
• The mid-series time skip and total setting reboot will frustrate readers who wanted the first world resolved cleanly
• Graphic violence and body horror put a hard ceiling on the audience
• It's dense, cold, and dialogue-light — that's either the appeal or a wall, depending entirely on you

Is Biomega Worth Reading?

Yes — especially if Blame! intimidated you. It's Nihei's apocalypse rendered with the same staggering art but a clear forward engine: a rescue, a chase, a faction war, and a planet that literally rebuilds itself halfway through. Just go in knowing the appeal is mood, motion, and architecture, not deep character drama. And the bear.
