K means "king" in English, that is, "king", and there are two sealed kings in various secondary elements. For example, King of Voids, Sakura Manzhi, Red King, Suoh Mikoto, Green King, Bi Liushui, White King, Izana Society.
H is the Japanese pronunciation of ェチ, which is the same as H. When Japanese and domestic translators are embarrassed to say "pornography" directly, they take this homonym instead.
Hope to adopt
