Does the Jin no Sho specify exactly what a KKG is? Because from everything I've read in the manga as well as heard in the anime is that KKG are abilities passed down genetically within specific clans, known as bloodline traits(Sharingan, Byakugan, etc). It's also to my understanding that dōjustu, abilities that work via users' eyes, classify as KKG. So knowing that Enton requires a Mangekyō Sharingan, a KKG bloodline trait, why does it not classify as a KKG despite it not being an advanced nature?
