From volume six chapter 50 THIS WOULD BE ON PAGE 12 OF YOUR onemanga LINK! This is the Japanese text that appears in the box beside Mihawk:
sekai saikyou no kenshi
taka no me no Mihooku
The worlds STRONGEST swordsman
Hawk eyes Mihawk.
The translation on onemanga is wrong. In an attempt to jazz up the language they lost the original meaning. It happens all the time, even with certain official translations. VIZ I'm looking at you~.
If you absolutely must have the page raw I'll gladly upload it, but it doesn't say anything that I didn't already type out.
