Yes, after casting his bloodline power on the variant type demon, what was standing in front of Blake was a child. An actual demon child.
Different from its body outside that was wholly covered in fire, the variant type demon in front of Blake didn't have any kind of fire covering its petite body.
A girl with short red hair, even redder than Vera, with red skin, and two tiny horns that were only slightly longer and thicker than Blake's index finger protruding on her head.
Both her torso and lower body were covered by a simple red cloth that Blake wasn't a single bit curious about where they came from, but the placement of those cloths and the shape of the child's body was enough for Blake to determine that the demon in front of him was a girl despite the short air that was only slightly longer than him.
Blake looked at the variant type demon in front of him, and so did the variant type demon looked at herself.
