Mai Kozuki (40): A talented pianist who is actually from the Underground's Melme Family (メルメ?), his music soothes the most savage of Underground monsters. Zeba orders the death of the family, and Mai is the sole survivor. Sugata saves her and brings her to the Maria Orphanage after rewriting her memories so she can live without her painful memories. Targeted by Bard Doggler, her hand is turned to stone and the Maskmen restore it.
