Illuge had bright pink skin and long messy black hair with many loose strands. Her crotch formed into a large toothed mouth with darker skin, a long tongue and splayed horns. Her feet had large claws and her arms formed into wings with large warped claws replacing the hands. She had a long spiked tail sprouting from the back of the crotch mouth also.
Illuge could fly using her wings, and her lower mouth could emit sonic screams capable of shattering glass at ease. Unlike her original counterpart her hands were replaced with deadly crab-like claws which she used to slash at prey.
However as they are going through the hallway to the buildings exit, Illuge's sonic scream powers out, shattering all the windows. Then, as if on cue, the octopus-like demon Texsch, and spider demoness Gardalza break in through the ceiling and chase the two through and out of the house. They escape in Ryo's car, however whilst driving they find the bridge smashed with Illuge standing on the other side. She roars as throws away her cloak before she swoops down and attacks them. The duo get out of the car, and Ryo shoots Illuge in her lower the mouth with his shotgun, causing her to fall down. After getting a distance, Ryo then shoots his car twice blowing up the engine and killing Illuge.
- In the art book simply titled The Devilman, there is a illustration promoting the OVA that features Illuge among other demons in the Black Sabbath party room, Illuge having a different look entirely, He design here still has the crab-like claws but at a smaller size, and her overall look is far softer and closer to the original manga incarnation.
- Her appearance in the OVA is one of the few times Illuge did anythign more than stand on a bridge and scream her vagina.
