So Kaido wasnt sensing Oden in Enma but was sensing Enma's presence and referred to it as Oden's hmmm, looks like Enma's will was so strong that it could even overpower Oden's own aura and present it as its own.
So Enma wasn't giving Zoro haki from Oden, nor was Oden's spirit leaving inside the sword, nor was it reacting to its master Hiyori , funny how I don't see my bros who were saying this stuff even 15mins
1. Zoro's Adv CoC + all three black blades with lightning spark.
2. Kuina and Kozaburo flashback.
3. Zoro's development with all the swords.
4. Zoro finding a way to damage King.
5. Zoro controlled Enma (hopefully he fully mastered it).
