People want straight up magic/ninjutsu to happen in One Piece.

Not going to happen in One Piece.

Haki (thereby premonition), Devil Fruits, and the effectiveness of hypnotism is about as magical as things will get.

"Why do you post this rando stuff?"

Bc as we see in reps, ppl just assume that aspects of the world are magical

They ignore that by and large, Oda abhors magic in this particular world. Weather 'sorcery' is the closest thing to it so far and even that likely has a science base

Also...if I'm aiming for accuracy... Ninjutsu as ninjutsu, fine. Yes. That's just being good at throwing shurikens and shit. That's real stuff. What I should've said is 'ninpou'. That's the scroll magic stuff. All of that will be DF-related.
