So much WRONG in one post.
LMFAO so the character who holds the title himself says "I'm not the strongest" but someone else who says he's still WSM holds more credit than the person who holds the title???? (make it make sense)
There's so much wrong in the Mihawk paragraph I'm just gonna give you bullet points.
- Mihawk never admitted inferiority simply stated WB is so far away he was testing the true distance, literally he's measuring the distance between Them and WB, that's it.
- If you believe that's Mihawk going all-out you might as well state right now Zoro can low-diff Mihawk.
- Since you mentioned this twice provide the panel of Mihawk saying he's inferior (or ch#)
Choice #3 is not an option cause it doesn't work, the titles stated by ODA (the creator) they are inverse a reality until proven false! That's how titles work.
We don't have all the details on Roger for us to know 100% but one thing is for certain Mihawk it's stated there is no one else who can challenge him in Swordsmanship he's the Strongest, he doesn't have anyone he can compete with.
AGAIN Kaido's title
WSC isn't a true title unless it's provided in an infobox like WB & Mihawk the WSC title is conjecture by the people of the OP world.
Kaido was a literal raid boss, it took an army to bring him sure Luffy got the winning blow but Luffy isn't beating Kaido in a fresh 1v1, moronic argument stating Luffy > Mihawk & Kaido.
