LOL No.
Thumb means to press, move, or touch (something).
If you get hit in the rib then you would guaranteed get knocked out.
Apparently every Sanji's attacks is sneak attack now?
Sanji was right in front of Vergo
Is Smoker sneak attacking Vergo?
Is Zoro sneak attacking Apoo?
And no, for the Flange Strike one, Sanji was right in front of Vergo, either Sanji is too fast for Vergo or Vergo just have a slow reaction/bad CoO in general. And they were fighting equally so Sanji didn't do any sneak attack here.
Here's the vision span.
Sanji is in range of Vergo's eyesight yet he couldn't react to Sanji.
So why Kata couldn't break Luffy's skull?
Funny because you guys were saying Sanji doesn't have haki and now you guys saying that Sanji was using haki against Luffy.
