…This isn't really the right place to ask about that, but I'll try to answer anyway.
@adamrochester:
i want to know how many episodes is there going to be
Nobody knows. The manga isn't finished yet, and doesn't show any signs of ending anytime soon, so at the moment, it's impossible to say exactly how long the anime will be.
@adamrochester:
and where can i buy them all from english version
Well, not all of the anime has been dubbed in English yet, but you can buy what's currently available at pretty much any store that sells anime and will ship outside the US. I recommend RightStuf, due to their low prices, frequent bargain-sales and quick delivery-time.
