A simple mercenary job led a poor apprentice to accidentally summon a silver-haired girl with mismatched eyes, whose strength seemed unfathomable, and bring her home. But...
She never imagined that the one she'd brought home would be not only a good-for-nothing who couldn't even recite the alphabet, but also a walking, talking **, and, more than that, a key to unlocking the truth of the world. When she finally fulfills her long-held wish and becomes a legendary archmage through her own efforts, will the world still be the same?
(This is a gender-bender yuri novel with a slow build.)
