Really love the OP, it's amazing song and singer is great.
Also then this is second major series to use relatively unknown amateur net singer for a theme song performance? [Unless I missed one aside from Bakemonogatari's ED last year] I guess it's becoming a more common thing which is a good thing in my opinion if so.
And I really looking forward to the ED since Ayana Taketatsu is suppose to be singing it herself
