Fight Details: Hashirama (Reanimation) vs. Madara (Reanimation)
Just like every other fight where you play as Hashirama, your secret technique is going to make it a breeze for you to wipe your enemy out. You want to hit him with the technique as many times as you can. Perform it immediately as he is standing still, or running toward you. Make sure to keep your health above 90% and once you use it for the 4th or 5th time, the battle should be over, and if you got an S Rank, the achievement is all yours!
