Is Mars Red Worth Reading? Review & Where to Read

Quick Answer
Yes, if you want a short, moody historical-vampire action series with real atmosphere — it's a tight three volumes, condensed from a stage play, that trades depth for mood and gets away with it more often than not.
Quick Verdict
“Vampires hunting their own kind for a government that barely trusts them is a great pitch, and the manga is at its best when it lets the setting carry the weight instead of rushing the plot.”
Best for: Readers who want a short, atmospheric historical vampire series with a military framework, and who don't mind a condensed, adaptation-paced story.
Not for: Readers who want deep characterization for a large cast, or who need a story with room to breathe rather than one compressed to fit three volumes.

Overview
By 1923, vampires have existed in Japan long enough that the government has a policy for them: register, accept monitored blood rations, and live under military oversight — or be hunted down. Code Zero is the unit built to do the hunting, and its members are, almost entirely, vampires themselves. Commander Yoshinobu Maeda leads a squad built around Shutaro Kurusu, an A-rank vampire who's managed to hold on to his humanity, alongside a handful of other vampires and humans whose loyalties don't always point the same direction. Mars Red follows this unit as its missions keep forcing its members to question what, exactly, they're being used for.
The manga, written by Bun-O Fujisawa and illustrated by Kemuri Karakara, adapts the original MARS RED stage play into three volumes, running in Monthly Comic Garden from 2020 to 2021.
What it does well
The core premise does a lot of work on its own: using vampires to hunt other vampires is a setup loaded with built-in tension, and the manga leans into the uncomfortable position that puts Code Zero's members in — enforcing a policy against their own kind, under the command of humans who see them, at best, as useful tools. The relationship between Maeda and Kurusu is the clearest beneficiary of that tension, a human commander and the vampire soldier he's come to actually trust, and it carries most of the series' emotional stakes.
The historical setting adds real texture, too. Taisho-era Japan was a period of rapid, uneasy modernization, and the manga uses that backdrop well — a society trying to absorb something new and dangerous (vampires, in this case, but the parallel to the era's real anxieties about change isn't subtle) without fully understanding what it's dealing with. And because the whole thing runs just three volumes, it moves with purpose; nothing here is killing time.
Where it falls short
That same brevity is the series' biggest limitation. Adapting a stage play into three manga volumes means a fairly large cast — Suwa, Takeuchi, Defrott, Aoi, Rufus, and others — gets introduced in quick succession without always getting the room to become more than a function in the plot. A few arcs that could use more space to land get resolved briskly instead, and there are a couple of turns that assume a bit more outside context (from the play or the simultaneous anime adaptation) than the manga fully supplies on its own.
Verdict
Mars Red is a short, atmospheric vampire series that gets real mileage out of its central premise and its historical setting, even when its compressed runtime doesn't leave room for everyone in its cast to fully land. If a Taisho-era military unit of vampires hunting their own kind sounds like a good pitch to you, three volumes is a low-risk way to find out — just go in knowing it's paced like an adaptation, not an original long-form story.
Strengths & Weaknesses
Strengths
- The premise — a Japanese military unit staffed with vampires, formed to police other vampires who won't submit to registration — gives the series a sharp hook and a built-in moral tension around what these soldiers are being used for.
- The 1923 Taisho-era setting is rendered with real atmosphere: a Japan modernizing fast and uneasily, which mirrors the story's own tension between the vampires' humanity and what the military wants to make of them.
- Commander Maeda and A-rank vampire Kurusu anchor the story well — their dynamic, a human officer leading a squad of the very thing he's ordered to eliminate, carries most of the series' emotional weight.
- At three volumes, it never pads itself — every chapter is doing work toward the ending.
Weaknesses
- Because it's adapting a stage play into a short manga run, the supporting cast — Suwa, Takeuchi, Defrott, Aoi, and others — get introduced faster than they get developed, and a few end up feeling more like set pieces than people.
- The compression shows in pacing: some arcs that would benefit from more room get resolved quickly to fit the three-volume structure.
- Readers unfamiliar with the original stage play or 2021 anime may find a couple of plot turns assume more context than the manga alone provides.
