Lancelot mobilized some True Yuan to wrap around his boots, ensuring they would make no sound upon contact with the ground, then cautiously poked his head out and looked towards the center of the interrogation room.
"Uh, bad news," the skull's voice echoed in Lancelot's mind, "That's not a soul-stealer fiend..."
Without Cromwell saying it, Lancelot realized that their earlier guess was completely wrong. The creature in the center of the room indeed had gigantic bat wings, but its skin was brownish-yellow, not the black that a soul-stealer fiend would possess; it had five fingers on its palms, which looked almost human despite the longer nails, but they definitely couldn't be called claws.
Most importantly, the aura it emitted didn't belong to Tanari, nor any Abyssal creature. Lancelot's Spirit Perception told him, without a doubt, it was a Demon, a denizen of the Barto Hell, mortal enemy of the Demons.
