Zoro not gonna open his eye
Nah joking aside, I'm only interested in how he lost it tbh. And by Occam's razor it should be done by Mihawk. But thay poses a question, like Mihawk doesn't want to fight "disabled" challengers as showed with Shanks, so why an exception for Zoro.
Anyway ye Zoro's lost eye isn't as big as a nerf like Shank's lost arm but I'm curious how Mihawk thinks of that.
