Stop Hitting Yourself
Used Counter Assault 30 times.
Can be done easily in Player Matches. Set the game to 5 Rounds and then 99 Time. Unlock Unlimited Hakumen and have the other player be any character. Just wait for your bar to fill up entirely and then have the other player hit you as you are guarding. Immediately after the guard, hit Forward+A+B. Hakumen should look like he does nothing, but it will waste half his bar. This is actually a Counter similar to his Drive move. If the person tries to hit you again too soon, they will take damage from it. Just repeat this 30 times and you will get the achievement. You should be able to get it by the end of all the rounds if you let the other player kill you a few rounds after doing as many Counters as possible. Unlimited Hakumen only takes about 10 to 12 seconds to charge all his Infinity Gauge. Do not activate the Infinity Super that lets you have infinite gauge, because you cannot do the Counter Assault in this mode.
