They are the master of the blood pond of Jigku.
As Kitarō and the others are being pursued by Hiotoko, they jump into a blood pond, but Nururibō attacked them with his leeches. Kitarō successfully defeated them with his remote control hands, finger guns, and internal electricity.
Leeches: Nururibō kept leeches within its body. These took in host's energy and thus sucked more bloods than normal leeches. All these were killed with Kitarō's electricity.
