Fics like Manteuffel the Glass

More than a century before Himmel the Hero defeats the Demon King, an eccentric mage attempts the impossible: summoning a human soul into the body of a young demon. The ritual appears to fail. The child remembers neither her name nor the world from which she came. Yet she speaks, fears and learns in ways no demon should. The mage names her and raises her in isolation, determined to discover whether humanity can be taught or whether a demon will always remain a demon. Long after his death. She will cross paths with Heroes, Greater Demons and an elven mage who will become the greatest challenge of her life.
