Princi is the Spider Devil, a devil who embodies the fear of spiders, and is a Public Safety Devil Hunter from Tokyo Special Division 4. Princi resembles a young busty woman with waist-length black hair. She has eight legs ending in scythe-like curved points which are sharp enough to stab through flesh. She appears to have a zipper in the center of her face with the pull under her chin to unzip upwards. She normally wears a shirt and elaborate bow-tie with a knee-length skirt. Princi usually takes a human shape so she tends to be friendly to humans and works as a devil hunter herself, however she will still kill people for just looking at her the wrong way. She showed no reaction at being mistaken for a human by the Violence Fiend and impassively killed zombies without any change in expression. She was bold enough to attack the Darkness Devill directly and showed no expression after being mutilated. She's also extremely devoted to Makima and will follow her orders directly, even if she has personal qualms with them.
