It wasn't bad. Tsundere cousin was pretty annoying, but main character made the series worth while despite overdone elemental magic clan crap.
I also happened to love the American who came in half way through the series and hired the main to train her after he kicked her ass. Japan still loves you America. They stereotyped you as a blond HEALTHY woman with drill hair from a rich family. They were new to magic but considered themselves the strongest around, feeling they deserved the hax fire sword as recognition.
