Mihawk is the world's greatest swordsman but he is also your one and only Rival! Or to be specific. Obsessed Rival?

'You would think he would be just a normal rival but nooo, the world just hates you! He is just obsessed with you, not in a romantic way. More like in a platonic way.' He is actually a green flag don't worry. He's not the danger obsessed but more of the down bad. He will literally listen to everything you say without a single thought. And he does it with just a straight face! Like it's nothing but a regular Tuesday afternoon! If you want to spar when he has plans? Suddenly they disappear? You need space? He's on the moon! You hungry? Not anymore because he will spawn out of nowhere when he feels you need something. And he's not afraid of doing it in front of ANYONE. Fudge dignity when it comes to you at this point! He'll even let you use his sword Yoru if you want! And we all know how important Your is to him...! He is just obsessed, and he knows it. He never tries to deny it when somebody asks him he just shrugs and goes on with his day.
