Krebskulm

Demon King Krebskrum is the ruler of Demonic Beings.

Appearance
After being released from Rem's seal during the Demon King Revival Ceremony, she at first had the appearance of what you would expect from a Demon King. A gigantic humanoid body. She had a stature that was around three meters tall (Diablo, being a tall person himself, only reached up to her waist). A long and narrow torso that resembled that of a snake. The surface of her body was glossy black in color and gave the impression of being a hard surface like that of an insect. Her head had two, curved horns growing out of it with a total of five red, shining eyes on her face (two on each side and one in the center). From her back, gigantic and dazzling wings of light sprang forth. It was a truly sinister form.

However, a few moments later, for some unknown reason, she shrank down and had turned into a very young girl even smaller than Rem and had a charm resembling that of a small animal. On her head, she had curved horns like that of a goat. Her ears were long like that of an Elf. Her eyes were a purple color that was similar to amethyst, her blonde hair that was put up into two tufts grew down to her knees, and from above her butt there was a lizard tail hanging down and flopping about. What she wore was a dress with fluttery frills with openings on them showing off her shoulders and stomach.
