@Blu Also I think if there are some KGs/Hiden that are from other villages, the player would have to explain how they got the technique in the characters history. Just to avoid confusion. For example, if someone wants to use Black Lightning that is exclusive to the Hidden Cloud and even more closely to the Raikage they would have to explain how they got a chance to learn that technique. It just makes sense seeing as we (The Hidden Leaf) are on odd terms with most villages and many do not cross sensitive jutsu to other nations.
Agreed. Please consider these things when creating your character... Unless your me. Cause I'm the GM. And my character is going to somehow possess all the Tailed Beasts. B)
