Quick Answer
Yes. Pluto takes an old Astro Boy story and rebuilds it as a smart, emotional sci-fi mystery. It's only eight volumes, so it's an easy one to recommend if you want something complete and a bit more grown-up.
Quick Verdict
“Turns a kids' robot story into an aching murder mystery about grief and war, and never wastes a page of its eight volumes.”
Best for: Readers who want a smart, character-driven sci-fi mystery with real emotional weight.
Not for: Readers who want fast action, or a long series to sink into rather than a short, deliberate one.

Pluto is a sci-fi mystery by Naoki Urasawa, the author of Monster and 20th Century Boys. It's based on a famous Astro Boy story by Osamu Tezuka called The Greatest Robot on Earth, but Urasawa rebuilds it as a darker, more grown-up murder mystery. It ran from 2003 to 2009 and is complete in eight volumes.
The setup, which is all you need going in: in a world where humans and advanced robots live side by side, someone is destroying the most powerful robots one by one, and a robot detective named Gesicht is assigned to the case. This review stays spoiler-free.
The big trick Pluto pulls off is taking a simple kids' story about a strong robot and turning it into something that's really about grief, war, and what separates a person from a machine. The mystery is the engine, but the themes are what stick with you.
It's also refreshingly tight. At eight volumes, Pluto doesn't have room to wander, and it doesn't. Each arc focuses on a different robot, fills in who they are, and ties back into the larger case. That structure keeps the story moving while still giving you time to care about the characters before things go wrong.
Urasawa gets a lot of feeling out of an unusual cast. Plenty of the main characters are robots, and yet the emotional beats land — partly because the writing treats them as people, and partly because the art is so good at quiet expressions. The pages are clean and easy to read, which matters in a story with this many moving parts.
The flip side of that tight length is that Pluto ends quickly. Some readers finish it wishing it had another volume or two to sit with the ideas it raises. It's a complete story, but it's a lean one.
A few of the later reveals also come together fast compared to the patient build-up before them. It's not a dealbreaker, but if you love a mystery that lingers on every clue, the later stretch moves quicker than you might expect.
Finally, it's loosely tied to an Astro Boy story. You don't need to know the original at all, but a handful of references and character names will mean more to readers who do.
Pluto is one of the best short manga you can hand someone, and an easy pick if you want a complete sci-fi mystery with real feeling behind it. If you want long-running action or a sprawling epic, look elsewhere — but if you want something smart, contained, and a little sad in the best way, it's well worth the eight volumes.

No. Pluto stands on its own. Knowing the original Astro Boy story adds a little extra meaning, but the mystery works fine without it.
