One of the scariest children you'll ever meet, Marcy is anything but your average Little Orphan Annie. Brought into Viper Mansion by Luccia, this little tot turned out to have mad fighting and magical skills to go along with her childlike playfulness, making those she face running scared, if they haven't been frozen, tied up, or had their legs broken first. Needless to say, she quickly rose through the Acacian ranks to become the youngest member of the Deva Dragoons.

Possessing her father's strength and her mother's affinity with blue spells, even the hardiest of duellers find it hard to keep up with this little girl. Laughing and dancing while flinging ice spells, water spells, strings like steel, and punches like marble, fighting Marcy is like fighting a child straight from a movie... a horror movie.
