I'm still not sure if Perona polishes his black blade or not
Blade polishes itself with Mihawk's Godly CoA
Perona is a house wife who just cuts vegetables and preps ingredients so Mihawk can cook.
He is a master of all trades
-Mihawk pulls bitches better than Oden
-Is a better cook than Sanji
-Is more lethal than Akainu
-Has strongest CoA
-Has stronger CoO than Katakuri
-Has attack power of Whitebeard
-Is richest pirate in the world because he doesn't share his treasure with anyone and owns massive real estate
