Ok really i HATE to do this but i did rate everything a ten. I cant find a reason not to there is something about this manga that stands out in everything that i have to give it that. I have never rated an anime having more than four 10s, so this is a big moment for me.

The story is just incredible. It has so much historical references that its like how can a manga be that much in depth. Really its nothing like the other shonen mangas where this random teenager gets this crazy power and fights random guys that are somehow doing something bad, just to save the day! Really RuroKen is nothing like that. It actually makes some kind of sense. Everything in the manga could in fact happen in real life. Somehow Nobuhiro (The Author) made it that it can happen for real and somehow still stand out. The story gets better as you read, i mean its so awesome at the beginning and it still gets better. Every arc in this manga took all those Shonen-Action animes and through them out. It made something so different from them all. The story has more than just the genres of Action and Adventure. It has a fullfilling romance part, Historical references and a historical backround, also really funny comedy parts. They all mix up and create a very in depth plot.

The art is really good. I can never see a part of it where he screwed up or drew something in less detail then he should. All the panels look very good. I cant even fond a part like those other shonen jump manga where they left out something in a picture. He will also draw a character next to another character that shouldnt be focussed on it all. That is really great because really if you think about it, if the characters there then he should be there even if its pointless. He can switch to this really comedic-goofy art that flows with the really excellent manga art.

The character are the best part of RuroKen. Everyone of them is unique in its way, and has a very a remarkable picture to them. Each one is developed really thurally, none of them are alike. Each one has a purpose, there are no filler characters at all. Its like they put really great detail into those villians that shouldnt have much of a purpose. Thats whats so brilliant! They all have their different motives and expressions for different things. Watsuki also relates a lot of them to different animals and objects. Which puts even more humor into them.

Really i am not a fanboy, so DO NOT think that. I really would suggest this to everyone. And this manga doesnt have a huge huge huge over-populated fanbase, so you can read it without getting annoyed.
Have Fun!!
