@sanjikun what does Wado has to do with taming Enma lol?
Bro like is Wado telling Enma "My man, I like Zoro, please don't take all his Haki?"
Wait you probably picture that happening don't you?
**** Tengu said "You are getting used to Enma because of Wado" because of craftsmanship which has to do with weight, sharpness etc, Zoro is adjusting to Enma quickly because he is used to using a similar sword. Like Shushui was a different sword, it was heavier and harder, Sandai was different, it was too sharp. Enma when it comes to its craftsmanship is similar to Wado Ichimonji.
Otherwise think about it, Kuina was used to Wado Ichimonji, does it mean when she picks up Enma, she would be able to Tame it?
Also ask yourself this question, if any of the scabbards had potential to tame Enma, why won't they actually do it and fight Kaido with it? Obviously cuz their Haki is not strong enough to do so.
Why are you so baised against Zoro? I literally don't get it, is Doflamingo wank that fucking strong?
Try to be a sane human being for once.
