Ronin Naruto hits 2-4 enemies with his standard, he attacks by default with his standard twice, if he kills someone he attacks again with his standard, and every time he uses his standard he gets a self buff of 5% to Attack. His chase (he chases twice) also increases his attack by 5% and Combo by 12%. His mystery hits 7, and causes Tag and knockdown to selected. There's also the Attack and Ninjutsu buff to anyone with full life in the same (I think vertical) row as him.

The tl;dr is, right now, he's broken AF. People think they're tired of 6P mystery, bored even? Wait till you get "Ikuze!"d to death.
