Quick question, why is it that Zoro and Oden always need to blacken their arms whenever they imbue Haki on their swords but Roger and WB just bypass the whole arm hardening thingy and just goes straight to imbuing their swords with Haki???
i was astonished when luffy didn't harden when he removed yamato's restraints..
idk if its a must to harden..
but when Hyo taught luffy he hardened it..
Kaido stated that the Scabbards were able to pierce him.. and Kinemon didn't harden his sword.
so bruh idk lol its random
