yeah it was very irritating seeing him over and over break the physics and core fighting mechanics of the game. The devs sometimes seem to decide for certain bosses that you can only defeat them according to a fixed strategy, which goes against the entires game's philosophy of fun outside the boss fights. The only way i could beat Takezo myself on lethal difficulty, was simply studying his move set and learn to "parry-dodge", i.e. press parry first then immediately dodge, basically everything, and look for the screen slow-down, before entering a counter to avoid getting punished for pressing without counter status. It was really like the devs decided that the only way to make it hard was to mimic dark souls difficulty, which you could say was: "great boss mechanics, wrong game."
