Now you are just lying
Everything I said is a fact that you can't debate against
The size absolutely matters.
I didn't dodge anything
That tiny black spark is zoro coating his swords in hardening the same happened in dressrosa
You can see all 3 swords clearly and only the closest sword has a tiny spark that isn't coc
This panel of zoro is even smaller and further away and the lightning trail is clearly much longer than half a sword
There is no lie you can make about this I cannot debunk
