Jumo is a Negamonster sent by Neflite to gather energy for the Negaverse. Like Dream Dolly, she has the appearance of a doll. She appeared in Sailor Moon Episode 15, Dangerous Dollies.

Her essence was implanted in a doll made by a girl named Mika. Once her energy reached its highest point, Jumo appeared from the doll to take her energy. Sammy tried to fight her, but she knocked him out. Sailor Moon battled Jumo. After the arrival of Sailor Mercury and Sailor Mars, Sailor Mercury discovered that her right ankle was her weak point. Before Sailor Moon could attack, Jumo began to strangle her, until Tuxedo Mask arrived. Sailor Moon then hit her ankle with Moon Tiara Magic, destroying her.
