It's complete!Source: ANN
Based off of a story arc from Osamu Tezuka's Tesuwan Atomu, Pluto follows the Europol detective Gesicht as he tries to uncover the mystery behind a string of robot and human deaths. The case becomes much more puzzling when evidence leans toward the murders being the work of a robot, which is something that hasn't happened for 8 years.
Ater reading Urasawa's masterpieces Monster and 20th Century Boys, I decided that I'd wait patiently on Pluto to be completed or until my patience ran out, before I read it. Thankfully the former occurred before the latter. For those familiar with his aforementioned works, you can expect the same level of excellence, but not as much mystery. He still has us guessing but it's not an emotional roller coaster like Monster and 20th CB. I loved it though.
I've never watched Astro Boy although I know of it (who doesn't really?), and it was very nice how he integrated Tezuka's world into this very adult story. And the more realistic looking Atom (aka Astro Boy) is very cute:
Ahem...anyway, I recommend this manga for anyone looking for a good complete seinen manga to read.
