Let's apply simple logic
Option 1: Divine Departure is an adv CoC attack
This means Shanks mastered adv CoC at the age of what, 15?
Conclusion 1: No DF brat Teach negged adv CoC special royal celestial dragon Shanks.
Conclusion 2: While we don't know Mihawk's level when he first clashed with Shanks, what we know is that he negged adv CoC user Shanks nonetheless. Even in such a crucial way, he got named WSS in the times after. Indicating a solid victory.
Teach hype ✔️
Mihawk hype ✔️
Option 2: Divine Departure is not an adv CoC attack
This means Divine Departure is clearly and undoubtedly a regular fucking sword swing. Ultimately destroying Hakiman theorists' ideological dreams of categorically separating the feat from Mihawk's specialty, swordsmanship.
Conclusion 1: 'Divine Departure is a blunt haki attack' and Hakiman theory fully and absolutely in the mud. Shanks’s signature move being < Mihawk by definition, ultimately settling the discussions of who's superior.
Conclusion 2: Teach just beat a promising young swordsman, nothing special.
No hype for Teach
Mihawk hype ✔️
What changes? Nothing.
Mihawk reigns supreme
