Sprite Tune (洛園堕とし) is a spell developed by the Fairy during the Great War. Not much is known about it, except that it was deemed the Fairy's "Trump card."
As a cliffhanger at the end of Volume 10, it was stated that Sprite Tune was cast and the Elkia Kingdom disappeared from the earth surface. What actually happened is yet to be seen.
