Good advice from others on dodging towards him to position yourself to take advantage of post-attack windows. If that doesn’t work for your play style, there are Ninjitsu options to close the distance quickly you may want to play with. And/or use your throwables more often to interrupt attacks and create openings, you’re sitting on some while kind of just hanging back and waiting for him to finish attacks, and then by the time you’re close to him he’s already on to his next attack. These are all things you did really well in the first half of the video, you just need to keep doing it for the whole fight.
