Defeating the Darkness that threatened Earth didn't come without cost-Lala used up so much power in the fight that she wound up shrinking down to a pint-sized version of herself. Spurred by concern, the Earth is getting an unexpected visitor. It's the Queen of Deviluke: the most powerful woman in the universe, and Lala's mother! How will Rito handle the arrival of a woman said to be so beautiful that simply looking at her drives men mad?
