Here is how u do it.
Right when u start the fight attack him to make him recover then back away. He will spin his sword. Hold block. When he is done he will hit u once with his sword. Combo him before he finishes his 2nd move. He will then recover. Then the 3rd or 4th time u get him down do powerstrike him. Keep doing this and the more times you do it the longer you can charge the power strike. Around the 5th or 6th time you powerstrike him it will show a breif cutscene and you will kill him and move onto stage 7.
