An alright ending I guess, a bit weak compared to the start and the main story but I appreciate what Naoki did. However, I love the way Naoki (and Tezuka as well) portrayed the dynamic between humans and robots, the more I read, the harder it becomes to distinguish between humans and robots but still, the line between them can't be broken. The character building, the emotional portraiting is also something worth mentioning, feel real and impressive.
"Pluto" is very different from Naoki's usual works but still a great read that I would recommended to everyone, a strong 9/10. Now it's time for 20th Century Boys :)
