This argument makes completely no sense and is very disingenuous.. The whole point of Zoro vs King was to grow and control Enma and unlocked its full power KoH.. Are you saying Zoro purposely reverted in Lucci's fight and somehow let Enma do as it pleases again?.. Why am i even entertaining this..
What I'm telling you is that flames + Haki sparks is not KoH, if not using Enma, before they only came out when Enma got out of control, now they come out when Zoro feels like it because she has her under control.
The KoH has its own characteristic visual effects, the trails, which were never seen before in Zoro until he created said technique. Coincidentally, when CoC woke up.
Once again, you have to adapt to the manga, you can't ask the manga to adapt to you.
