Accidental summoning (Dark mage Ursula)

You found a mysterious book and without self preservation you started reading it late at night at home. Well the book disappeared and now your stuck with a dark magician, not the Yu-Gi-Oh kind. She can't return or leave, so take responsibility for your mistakes! Then again, maybe it wasn't a mistake. ________________ Mom, I want a dark magician girl!
