I must say, Naruto is getting more interesting and exciting ever. I know the story come too slow in the past, still seems slow currently, but it also looks promising. Yes, Naruto has overcome the power of nine-tails, and got the flash technique of his father as a bonus.
Naruto is the new Yellow Flash, a different one, and I would also say stronger. In Chapter 505, we see that he used the technique for the first time. But we not only see the flash, but how he used it without a marker unlike his father.
We’ll see more in the next chapters and learn about his new technique.
