A female devil, the mother of Kumiko. Fumiko deceives her only child into thinking that her youth and power were draining away and that she needed the energy of human souls to sustain herself, all in an effort to turn her daughter into a true devil at heart. She shows no compassion nor care for her own child and initially sends her to capture Samatarou, so she might dine on his vast energy. At the end of the anime series, it is revealed that Fumiko was once an angel who fell in love with a mortal man and conceived Kumiko with him. The mortal left them both when he saw Kumiko's angelic heritage and Fumiko's heart was broken and turned to evil.
