You would think it wouldn't be that expensive to hire 7-8 other guys, and he could do all the rough drawings still. then you could tell a way longer and more detailed story or have an incredible fight without taking a year to do it.
Plus, I think a manga released every day would be way more popular then weekly shonens.
This thread has been made various times before and the answer is still the same.
First of, are you talking about chapters or actual manga volumes? Because there's obviously a difference between them. No mangaka can create an entire manga in a day, every day. Same goes for creating a chapter.
A chapter isn't made in one day. First of the mangaka has to make some drafts, a quickly sketched chapter showing what he would like to have happen in it. Then he goes to do his editor and the editor will decide whether or not the chapter is good as it is. If the editor finds fault with it, the mangaka has to redraw the drafts again and go back to the editor until it's approved.
Once the editor approves of the chapter, the mangaka (and his/her team if he/she has it) can start drawing the chapter for real. That includes adding background, shading ... which is usually done by the team if he/she has one.
Then the chapter can be send to the editor.
If you actually had taken the time to look up Kishimoto-sensei's schedule, you would realise he already has barely any free time with drawing one chapter every week (he has only around four hours of free time every day, which includes sleep). And you want him to release a chapter every day? That's impossible.
Weekly chapters are good enough. It's not like you have to wait long for a chapter to appear. I'm reading Black butler as well and guess what? That magazine only publishes one chapter a month.
One chapter a month. Do the fans complain? No. Yet we have to wait a whole month (now even longer because there won't be a new chapter in April) for a new chapter to appear, which is longer than we have to wait for Naruto to appear. But for some reason I never see them complaining on that forum about the long wait ...
About hiring other people: a mangaka has to hire people from his/her own money. You have to have a really popular manga before you get a decent income (decent enough to only have manga drawing as your occupation -> that's the reason why most mangaka have another job as well, because they can't live of the money earned with their manga sale) which would make you able to pay other people.
Kishimoto-sensei does have a team; don't know how many, but too many would just slow them down. And yes, hiring them is expensive.
And if you really mean manga volumes instead of chapters, do you really think that releasing one manga every day (which again is impossible) would do the sales good? Already there are a lot of people who just read the manga online instead of actually buying the volumes, and releasing one manga every day would make people decide to just read it online instead of buying it because it would get too expensive for them then.
So no, releasing a manga every day would be really bad for the sales.
I'd say he already has a pretty detailed story, considering he's been drawing it since 1997.
