I know that anime, I remember I've seen it , it was nice ; but I was refeering to the manga of Sanpei Shirato now I found it .
Yes I know Ninja warriours tv programme , I like it a lot. I really think that ninja are soo cool !
Yes abroad we know this tv programme there is also a version of this in my own country ... but if you talk about Sasuke one of the first things that I believe it comes in mind is : Sasuke Uchiha ... Naruto's anime and manga is really really popular abroad.
