It's called kamui, not "kumai" or "kumi" or "kami." I don't know if half of NB is dyslexic or just plain dumb, but seriously. It's a 5 letter, commonly seen attack. Learn to English, guys.
Edit:
Before you all freak out on my for "Learn to English," it was a joke.
Edit:
Fair point. Learn to type/read.Kamui isn't English...
