Oda: Uses the same SFX that he used for Togen Totsuka to make things clear even to the utterly confused.
WG Prodigies : Kaido prised them for failing to cut him.
How about showing an actual cut on his skin, in a focus panel.
The Scabbards drawing blood from Kaido for the first time had a whole moment built around it, with clear images of the damage done.
Luffy drawing blood from Kaido for the first time had a whole moment build around it, with clear images of the damage done and Kaido seeing Legendary shadows behind Luffy.
But Zoro drawing blood for the first time is supposed to be this combo attack with Killer, where we don't even get any focus on the damage done by Zoro, let alone a moment dedicated to that achievement on his part ?
And based on what ? A SFX shared with Killer, that in Killers case is shown not to draw blood, but it's assumed to do with Zoro by some of you ? Or are we saying that Killer's attack had no SFX and that's all Zoro ? Would Oda not use a different SFX with Killer that's indicative of not doing damage to further separate the two ?
Even in this convoluted bs way of looking at things that does not account for how the scene would be written in the context of the story and not random forum debates, it still does not make sense.
