just a coincidace...Hey, you could be onto something here! Note that the shape of your diagram is the EXACT same as Sasuke's Mangekyo Sharingan!
Yeah I believe there are more Kekkei Genkai/Advanced Elemental Jutsu anyway.just a coincidace...
Just tell me the reasons why should Naruto have 2 Elements?!
Vause If you have more elements that makes you stronger?!WRONG!Knowing how to use an element makes you better!
For me Naruto is not going to have a second element...He doesnt know any other jutsu than Rasengan,Kage Bunshin,Rassenshurnken and Sage Mode and Jutsu's Related to the previous ones!
That is going to be his advantage!If he is going to leanr these & also Fuuin Jutsus because it is his clans speciality...
