Overview

A virus called N5S is spreading across Earth, turning most of humanity into shambling, disfigured "Drones." Zoichi Kanoe, a synthetic agent working for a shadowy corporation, rides through the wreckage on a motorcycle with an AI companion named Fuyu, searching for the rare humans whose bodies can resist and transmute the infection. Biomega is Tsutomu Nihei working in familiar cosmic-horror-adjacent sci-fi territory, but in a tighter, more contained form than his sprawling epics.

What it does well

The art is doing most of the heavy lifting, and it's doing it extremely well. Nihei's linework turns collapsed cities and infected mobs into something that reads as genuinely alien and wrong, long before any dialogue tries to explain what's happening. That's the point — this is horror communicated through scale and texture rather than exposition, and it's some of his most controlled work in that register.

Zoichi and Fuyu's dynamic gives the story an emotional throughline it badly needs. Everything around them is cold, hostile, and largely silent, so the motorcycle-and-rider partnership — genuinely a little tender in places — stands out as the one warm thing in a very bleak world. It keeps Biomega from being pure atmosphere with nothing to hold onto.

Six volumes is also, in hindsight, the right length. Nihei's longer series can sprawl to the point where plot momentum gets lost in the scenery; here, the shorter runtime keeps the tension from slackening, and the horror concept (infection as slow, bodily wrongness) never overstays its welcome.

Where it falls short

This is not an easy read if you want your sci-fi clearly explained. Nihei's dialogue is sparse even by his own standards, and a lot of the plot's mechanics — what N5S actually does, why certain people resist it, what Zoichi actually is — are left for the reader to piece together from fragments. That's a deliberate choice, but it's a real barrier for readers who want their world-building spelled out.

Zoichi himself stays somewhat opaque as a character for much of the story; you understand what he's doing more clearly than why he's doing it, at least for a good portion of the run. And practically speaking, the English print run is out of print now, so getting hold of it costs more time and money than the reading experience itself requires.

Verdict

Biomega is Tsutomu Nihei doing what he does best in a tighter package than usual — dense, alien horror-scale art driving a story that trusts you to fill in the gaps. It's not an entry point for readers who want clear plotting, but for anyone who already responds to his style, this is one of his most focused and satisfying works, even with the frustration of hunting down a copy.
