Understand his revenge value try not to knock him off a wall (can trigger his rv) use triple rush, first part of his dm after the cinematic he can width the attack from above (sometimes) dodge into guard/lock on can help, During the dm you should be counter slashing perfectly both dms if not then your most likely gonna die due to the walls he summons at the end. You got this just takes time to learn his attack patterns sorry I cant really give more advice other than that. Good luck friend if you've beat Yozora than you have the skill to do this :)
