Kaidou realizes that Zoro's sword has strange Haki because it one belongs to Oden
With the caveat that the spoiler provider could be tripping, and i hope he is to be honest, how is this not saying that the strange Haki from Enma is there according to Kaidou because the sword belonged to Oden ?
And the fact that only the slash from Enma seems to go through the scales, and only Enma is said to have this strange Haki after a Santoryu attack.
It's pretty fucking weird, but it's either Oda's doing, or the spoiler provider messing up what's being said.
