MC is reincarnated in the Naruto world at the start of the second ninja war. He wants to fight the war and make a name for himself but there was a little bit of problem he doesn't have a chakra, but what he have is something special he can bend elements at his own will. He will train every elements to master them his first bending abilities would be the basic elements from there he would have to train harder to try to master the advance elements.
