What was the ultimate way to surpass an opponent's sword style? Simply correct all the flaws of that style to create a more perfect one, and the new would be plainly superior to the old. The new style would account for all the old style's faults, and even compensate for its weaknesses. It would eclipse its precursor in every offensive and defensive situation.
