The whole concept of the "Pure Swordsman" was someone who lives and dies by the Sword. It's what separates those who are actually Swordsmen, and those who are not. But you wanna chime in with this stupid "Hakiman" bullshit.
This entire King fight, and Wano Arc has proven that. King doesn't consider himself a Swordsmen, and doesn't give two shits about his Sword. Meanwhile, Zoro's about ready to jump off a floating Island thousands of feet in the air in order to save his Swords. In order for Zoro to truly Master Enma, he had accept and learn to fight without restriction, and give himself completely to Enma.
