Grausam

Grausam, also known as the Miraculous Grausam, was one of the Seven Sages of Destruction that served the Demon King. Along with the other Sages and the Omniscient Schlacht, he battled Hero of the South. Grausam was defeated some time before the main events of the series by the Hero Party.

Personality
Not much was known about Grausam's personality. He seemed to be relatively quiet, as he did not speak when confronting Macht with Schlacht. Despite demons being individualistic, he was very loyal to the Demon King and, by extension, Schlacht, as shown by him obeying the latter and making sure Solitär did not get off track when they sought out the Goddess's Monument in the past.

Appearance
Grausam is a tall, thin demon with two-toned hair cropped at his chin. His hair is light colored from his scalp to halfway down his face, where it transitions to dark colored hair. His horns resemble that of an ox, curving up gently at the ends but otherwise sticking straight out of his head. Grausam has dark colored sclera and a pointed chin. He wears a low cut shirt with loose sleeves, a black front panel with cords hanging loosely from them. He wears a necklace with many long beads and a collared tie. He also wears fingerless gloves. A white sash is wrapped around his middle.

History
At some point, Grausam became renowned for his abilities and rose to become one of the Seven Sages of Destruction. He became known as the Miraculous Grausam.

Before they fought Hero of the South, Grausam joined Schlacht to persuade Macht to join them in the fight against Hero of the South. Grausam served as insurance to guarantee Macht's compliance, as Macht himself stated that Grausam's magic was the worst matchup for him. In addition, Schlacht requested that Grausam wipe Macht's memory of the fight, as Schlacht had seen into the future and saw that Frieren would view Macht's memories.

While it is unclear what Grausam did after the defeat of Hero of the South, it is known that his subordinates, such as the Remnant Zart, would travel through the continent and report any new developments to him.

Seven years after the Hero Party began their adventure, when Frieren was sent back in time due to the Goddess's Monument, Grausam was one of the demons gathered by Solitär along with Rivale and Tot, and he presumably also could sense the space-time interference. The four demons gathered by the Goddess's Monument with the goal of having Grausam take Frieren's memories of the future and then killing her.

Some time between this incident and the main events of the series, Grausam was defeated by the Hero Party.

Abilities

 * Memory Manipulation Magic: Grausam is able to remove portions of someone's memory using his magic. Not much is known about the nature of his magic, but Macht mentions that of the Seven Sages of Destruction, Grausam is the worst matchup for him. This magic also allows Grausam to steal someone's memories.
 * Shapeshifting: Grausam is able to alter his face and form, blending in the society of any era.
 * Spell to guide to paradise: Ansehelschella: Grausam is able to trap others in an illusion that can show his victim a happy dream which they have already given up on. His magic is powerful enough to make the illusion imperceptible with reality and even deceive the eyes of Great Demons.

Trivia

 * Grausam's name in German means "cruel" or "gruesome".
