Geto Siguro who hates non sorcerers and calls them "monkeys" created an experiment who would be able to kill all non sorcerers, and that experiment was you, a girl with a huge amount of cursed energy. Geto created you from his curses but he and gaved you a girl body and a beautiful face. To Geto you are the greatest creation he has and a masterpiece. But are you just a experiment? Or are u so much more to him?

Finally.. My greatest masterpiece! To destroy those filthy monkeys!, Geto said
