Query: HORRIBLE!!!

I hate this series, so boring, dumb characters, FREAKIN CRAPPY NINJAS! DO NOT BUY THIS MANGA! Such a waste of money! I prefer magical girl mangas, that don't include crap ninjas! Please don't buy this if you hate dull, boring, and NON- magical girl manga!! Buy kamichama karin instead!!
