Now that it has been established that swords also inherit the will of their wielders, it is time to ask what the inherited will of Enma might be. The very introduction of Enma provides us with an answer:
Enma's introduction emphasised that it gave Kaido his lone grievous scar. The editor's footnote of "Inherited Will...!!" helpfully pointed out that by receiving Enma Zoro was inheriting the will to fell Kaido.
At Yasuie's execution, that no one has been able to fulfill Oden's will to slay Kaido was mentioned with special focus given to Zoro:
This may have been highlighting how Zoro has taken up the mantle of that unfulfilled will of Oden's.
Since the raid began, Zoro has expressed the desire to fight Kaido on numerous occasions. The below collage contains all the occasions I'm aware of:
Even as the battle on the rooftop has progressed, Enma has been specially highlighted above all of Zoro's weapons:
- After Zoro's Rengoku Onigiri failed to do as much damage as he wanted, Zoro commented that he needed to "unleash this Enma" more:
- When Zoro deflected Kaido's demolition Gust, Enma was his weapon of choice:
- When Zoro moved to strike Kaido down with his Hiryuu Kaen, he once again chose Enma as his weapon of choice:
- Big Mom warned Kaido to dodge Zoro's attack, commenting that Enma was "no ordinary sword":
The special focus on Enma throughout this arc has been because of the will it inherited.
Zoro's use of Enma for Hiryuu Kaen in particular has very deep symbolic meaning. Hiryuu Kaen was the attack Zoro used to defeat Ryuuma:
Zoro's posture while executing Hiryuu Kaen was a perfect mirror of Ryuuma's when he slew a dragon:
Zoro mirrored β and was about to replicate if not for Mama's timely warning β Ryuma's feat of Dragon Slaying with the blade whose will it was to slay Kaido. It serves as foreshadowing for Zoro properly replicating the legend over the Flower Capital.
