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. Growing from the left and right sides of 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, cream-colored 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.

When she first entered Faltra City with Diablo's group, she had to wear Alicia's mantle as a robe in order to hide her horns and tail so that she can pretend to be one of the demi-human races. However, when she and Edelgart was discovered by Mei to be Demonic Beings, Mei helped to disguise her and Edelgart since they were paying customers. After Mei used her makeup techniques, Krum was made to wear an idol-like outfit. Since she had transparent-like skin that had no need for makeup, eyeshadow was put on her eyelids, and eyeliner was put on the underside. With a hat, her horns were made to look like decorations. In order to hide her tail, she wore a parasol-like skirt.

Abilities
Krebskrum has tremendous magical power. As Diablo describes it, it was magical power that was enormous enough that it was difficult to comprehend. Diablo also describes that unlike normal magicians who have magical power stored up in their body, Krebskrum's magical power was as if he was taking a peek at a flowing river; seemingly having unlimited magical power.

However, because Krebskrum regressed back to a child, she has forgotten all the spells she had knowledge about as a full-grown adult. In her child form, the most she can do is bestow magical power upon Demonic Beings to make them stronger and destroy her enemies with basic magic blasts.

When Krebskrum returns to her true form as the Demon King because of her intense hatred for Rem's "death", her magical power further increases. Along with that, knowledge of her other abilities seems to have returned to her like infusing magical power into her fist to increase the power of her punch, a <> attack, and a magic spell that seems similar to <>. If her powerful magic and deadly <> attack is not enough to destroy her enemies, Krebskrum will resort to using her enormous strength to crush her foes with physical attacks or throwing heavy objects (like when she threw coffins and portions of the rampart at Diablo).
 * Immense Strength: Krebskrum's strength is capable of lifting and throwing heavy objects, like coffins and large portions of the rampart, with ease. And when she infuses magical power into her fist to throw a punch, its power is so incredible that it blows away any armor or defense made by the people of the Races as if it was nothing. Not even Diablo's <>, with its Physical Damage Reduction, can withstand its power.
 * Powerful Magic
 * <>: a pure <>.

Trivia

 * When she was first revived and became hungry, Shera gave her a biscuit. After eating it, it became Krebskrum's favorite food.
 * As she was trying out foods from different bakeries and restaurants with Diablo's group and Edelgart, not only did Krebskrum discover many different kinds of biscuits and confectioneries similar to it, she also discovered her second favorite food, chocolate.
