From what I can tell with my intermediate knowledge of Japanese and a (very) lazy scan, Nekomusume has invented a new form of enjou kousai: neko kousai. At least that's what I think the NK thing means. Japanese slang (or foreign slang in general to a learner) is an ass. That, or she's talking about NeKo-style something or other, was too lazy to translate the rest in context.

@GEnkouhande
I don't know enough kanji. It's an ass already to translate a page of any doujinshi since I have to stop nearly every kanji. Intermediate still means effectively "useless" for reading Japanese.

Would be nice if you could do a translation translation. Put your intermediate knowledge to intermediate use.
