Sadatame is the boss fight. First you will fight Sadatame and take him to half health, once this has occurred you will fight 4 of his goons, which are the default easy enemies and upon killing them you will finish off Sadatame.

To do this I parried his attacks in order to stagger him and quickly used the , Attack. Sometimes he does attacks that are hard to parry so don't be afraid to block them too. I had the best success parrying the attack where he swings his weapon horizontally. He usually activates this attack when you're quite close to him. He has another attack where he will kick and then do a heavy swing which will stagger you if you block. Be aware that if he staggers you, it will count as being hit even though you don't take any damage. To be safe block the kick and then roll away from him. Watch your stamina and make sure you have enough for the second phase although that shouldn't matter if you're doing it on a lower difficulty.

I did this on Ronin so each , attack took 25% of his health away, however you will do a lot more damage on lower difficulty. If you are doing this on Ronin and have trouble with the regular enemies in the middle, simply block and quick attack + , or + , which is very consistent.

Keep some distance from him and be ready to parry then strike twice with heavy attack. He will step out and send the goons in, finish them off and he will jump back in. Keep some distance and be ready to parry then two more heavy attacks will finish him off. If you get hit just pause and load your last checkpoint.
