Look at Enma's behavior up to chapter 1033, until Zoro independently began to pour a bunch of hacks into the blades after realizing what enma wants. 1 Hazy haze is ALWAYS only around Enma. 2 The hand that holds the Enma dries, not the whole body. 3 Excess hacks do not appear around other swords. 4 According to you, enma gives the user the opportunity to release hacks, more than the user can without enma, if this were the case, then the haze around all the swords would be immediately (still on the roof), and not only around enma and Zoro would dry up with his whole body, and not just the hand holding enma. Output=Enma sucks the user's hacks through the hand holding it, if he does not give a lot of hacks to the blades on his own, and not like yours, allows the body to release more hacks than the user can. There was not a word about this in the manga. On the roof, by the way, Zoro stopped restraining enma and his hand did not dry out, in ashura he gave everything that was left and why there was no excess khaki on other swords. Zoro on the roof "unleashed" enma, according to him. Where is the green haki aura on the other swords?
