Streets of Rage 2 - Kazuya Mishima playthrough

I am playing MetalHead84's unique SoR2 hack named “Streets of Rage 2 - Tekken Edition“, where instead of Axel and Blaze you can play as Jin Kazama and Kazuya Mishima. The sprites are very good and fit the SoR climate. They are not overpowered and a knife attack takes more damage. There are also the soundclips from Tekken 5. It's like the 2D version of a Tekken Force mode. This time I am playing as Kazuya Mishima and I succeeded to do a playthrough in the Hardest difficulty. I found a certain strategy on . Before I start fighting him, I am beating all of the enemies, that appear while a boss fight.
