it's not like Gai can open all 8 Gates at once and in 1 second, it does take some time, even tho it might be only like 4 seconds, and Kakashi's sharingan CAN'T keep up with A's armor, so how do they win please? OH, and let me remind you, Sasuke's Chidori did almost nothing to A, Kakashi's Lightning Blade is only a bit stronger, so i doubt it would hurt him badly, so only chance Kakashi has is Kamui which is seriously risky8 gates ends Ay if not hes slowed down enough to be kamui'd
Kakashi's raikiri is a much more powerful version. It went from an A-Rank to S-Rank because of how much more concentrated it is. If it could penetrate A enough to kill him, I dunno, but it'd do better than chidori.it's not like Gai can open all 8 Gates at once and in 1 second, it does take some time, even tho it might be only like 4 seconds, and Kakashi's sharingan CAN'T keep up with A's armor, so how do they win please?
