KAGURABACHI REACTION: And My First Impression of ONE PIECE 1137!

Hey dude, kata is not a mistranslation, a kata is a proper stance you take in a martial art or, in this case, swordsmanship, to deploy an attack.

Also, at the end of chapter 64, with Kuguri: if you pay attention it's obvious, the thirst for a good sword fight is taking all of the space in his head, literally pushing aside every other need he has in order to satisfy his need to fight.
