Though i know that there are certainly some Mangaka that deserve more this distinction, i don't really care. Say what you want but i will support
Masashi Kishimoto. He has created one of the best Shounen ever IMO, and though it has been more than 10 years since he created Naruto, it still keeps being interesting and though i don't think that Kishi had everything planned like for example Oda much likely had regarding One Piece, it's still a beautiful and really coherent story. I freaking love everything about it. The universe, the characters, the fights. And one thing that Kishi definitely deserves props is the fact that imo he doesn't really drag the story. Most of the chapters end being important to the story itself.
I am the type of people, that likes to end the things that gets obsessed with in the less time possible, though after reading/see * whatever is the case* i get angry with myself for being so fast
* But when you are hooked on something, you want the story to progress and Kishi actually does that.
There are great manga out there, but how many time did the authors need to draw it? Berserk, Hunter X Hunter .... definitely great manga, but each of them completely fail on making me addicted on them. These kinda of works can only be fully enjoyed if you are reading them when they are already completed.
I still remember when i first saw Naruto. A friend of mine had already talked a bit about it to me, but as most of the people, i only started valuing it when i first watched Naruto. So there was a time where Naruto anime, was airing on TV. After it ... i got really obsessed with it. It was more than 3 years ago, and on that time i didn't even had an idea about what manga or anime were. Even though i am not an anime fan, i prefer manga, there was a time where i watched more than 30 episodes of Naruto in a single day. It was crazy. I caught up with the latest episode out on that time, and then i discovered the manga. After that i have been following Naruto, and even though it had its ups and downs i never was behind for more than 2 chapters, and on times i were it was because i was out on vacations
Kishi takes this category for me, for keeping the story interesting, for making believable characters and for the awesome plot, that isn't predictable at all, and that can be seen by the fact that Naruto section is without any doubts one of the sections with more movement.
