This is only normal dificulty...
Basically... attack from the distance, Saiki got an unblockable pretty powerful ( and annoying) move if you get too close and he does it all the time. He is strong but he is not very fast and he makes a grunt before attack so its not very hard to block him. That's it, attack from the distance and when he grunts, go back to block the black fire and you should be fine.
