I managed to beat the katana general in the big stairs of the castle.First I killed his 4 sniper lackies with shurikens. Not gonna lie, I cheesed the fuck of roofs, grappling to them to heal and attack from the air. The fucker has troubles sometimes with the air attacks from above, and even if they don't connect at least he is not 2 shotting you on the floor or killing your posture bar with his combos.
Wanna be cheap Miyazaki San? Bring it on!
The problem is gonna win the lady's fight second stage without cheesing.
