The Most Important Issue

"Heh, I can't say it's a sure thing. But based on the information we've gathered so far, Darui seems to be the strongest contender. And in terms of individual strength, he should be about on par with the average of the Five Kage throughout history. Unless you learn Senjutsu, you probably won't be able to beat him, Neji."
