No he is a swordsman, but his title is Kenshi.
It’s an honorific similar to how senpai and sensei denote levels of seniority.
A Kensei would be a higher title than Mihawk’s.
You can literally fact check me on everything here, I’ve been working on a much longer thread on why Nusjuro is probably above Mihawk
We don’t care abt how he is called as a swordsman
It can be daikengou, kensei or kenshi like u said
What matters is that mihawk is the strongest Swordsman in the verse
He has the strongest sword ,
He is the peak of sword skills
Nothing comes close to him
And his blackblade is a living proof of his stature , something which eos zoro ( stronger than Venusjuro will have )
This is literally becoming the same debate as the daikengou one with shanks
Another debate which will age like milk 🤷♂️
