Monster Review: Naoki Urasawa’s Perfect Thriller

Naoki Urasawa's flawless psychological thriller manga.

person walking between trees

Imagine you are a gifted young surgeon, and you make one principled decision: you save the life of a critically wounded child instead of the town’s wealthy mayor. Years later, you discover that the child you saved has grown into a serial killer — and that your choice set him loose on the world. What do you do? That is the engine of Monster, Naoki Urasawa’s landmark thriller, and it drives one of the most relentlessly tense stories ever told in comics.

This is our full review of Monster — the setup, the craft, the content you should be prepared for, and why we consider it a near-flawless piece of storytelling in any medium.

What is Monster?

Monster is a psychological thriller written and drawn by Naoki Urasawa. It was serialized in Shogakukan’s Big Comic Original from 1994 to 2001, running to 18 original volumes, and is published in English by Viz Media in a handsome nine-volume Perfect Edition (each collecting two of the originals). It is complete.

The story follows Dr. Kenzo Tenma, a brilliant Japanese neurosurgeon working at a prestigious hospital in Düsseldorf, Germany. Passed over and manipulated by hospital politics, Tenma defies orders and saves a gravely injured young boy, Johan Liebert, over a more socially important patient. It costs him his career and his engagement. Nearly a decade later, a trail of murders leads Tenma to a horrifying truth: Johan survived, and he has become a charismatic, utterly remorseless killer. Tenma resolves to undo his mistake and stop the monster he saved.

The story: a manhunt with a conscience

On its surface Monster is a chase — Tenma pursuing Johan across Germany and the Czech Republic while himself framed for murder and hunted by police. But Urasawa is after something deeper than a thriller’s mechanics. The book is a sustained meditation on the value of a single human life, on nature versus nurture, and on whether evil is born or made. Every character Tenma meets on the road becomes a small, complete story about kindness, damage, and choice.

What makes it extraordinary is the discipline. Urasawa juggles an enormous cast and a plot that reaches back to Cold War experiments in the former East, yet never loses the thread or the tension. Chapters end on quiet, chilling beats rather than cheap cliffhangers, and the mystery of who Johan really is unspools with the patience of prestige television a decade before that became the norm.

Johan Liebert: one of fiction’s great villains

Johan is the reason the book haunts people. He is soft-spoken, beautiful, and terrifyingly persuasive — a villain who rarely raises his voice and almost never kills with his own hands, preferring to talk ordinary people into destroying themselves and each other. Urasawa resists the urge to over-explain him, and the slow, partial reveal of his origins is one of the series’ great pleasures. He belongs in the same conversation as Hannibal Lecter and Anton Chigurh.

The craft: Urasawa the master storyteller

Naoki Urasawa is, by broad consensus, one of the greatest cartoonists alive, and Monster is often cited as his finest hour. His art is naturalistic and restrained — real-looking European faces, real cities, no manga exaggeration — which grounds the horror in a recognizable world. His true genius is pacing and “acting”: a held reaction shot, a shift in body language, a single panel of a character realizing something terrible. He trusts the reader completely, and the story is richer for it. If you admire his later Pluto, know that Monster is where that mastery was forged.

A story rooted in a real place and time

Part of what gives Monster its weight is its setting. Urasawa grounds the story in the Germany of the early 1990s, in the immediate aftermath of reunification, and reaches back into the Cold War history of the former East. The trail Tenma follows leads to a defunct program that tried to engineer perfect human beings — a chilling echo of real twentieth-century horrors — and the manga treats that history with sober seriousness rather than pulp sensationalism. The European settings are meticulously researched, from Düsseldorf and Frankfurt to Prague, and that specificity makes the nightmare feel disturbingly plausible. It’s a rare manga that could sit comfortably on a shelf beside John le Carré or Patricia Highsmith.

Content warning

Monster is a work for adult readers. It deals with serial murder, child abuse, psychological manipulation, suicide, and the aftermath of state-sponsored experimentation on children. The violence is rarely graphic in a gory sense — Urasawa is more interested in dread than shock — but the themes are genuinely disturbing and linger long after you put the book down. It is bleak, humane, and heavy in equal measure.

The verdict

Monster is as good as serialized fiction gets. It is patient, humane, morally weighty, and impossible to stop reading once Johan’s shadow falls across the page.

It is, quite simply, one of the finest comics ever made.

Frequently asked questions

Is Monster finished?

Yes. The manga ran from 1994 to 2001 and concluded in 18 volumes, collected in English as nine Perfect Editions. It is a complete, self-contained story with a definitive ending.

Do I need to read Monster before Pluto or 20th Century Boys?

No — Urasawa’s major works are separate, standalone stories. If you love Monster, though, we’d point you straight to Pluto next, then 20th Century Boys.

Is Monster appropriate for teenagers?

It’s written for adults. The story centers on serial murder, child abuse, and psychological manipulation, and while it’s rarely gory, the themes are genuinely disturbing. We’d steer younger readers elsewhere first.

What’s the best way to read Monster in English?

The Viz Perfect Edition — nine larger paperbacks, each collecting two original volumes — is the definitive version, with better paper and printing than the older out-of-print releases.
