Lügner

Lügner (リュグナー) was a demon who served Aura the Guillotine. He infiltrated Graf Granat's Domain under the guise of serving as an envoy of peace from Lady Aura, though his true intentions were to get Graf Granat to lower the defensive barrier surrounding the city.

Personality
Lügner appears to be a laid-back and empathetic. He is forgiving of Frieren when she attacks him, and relates with Graf Granat about his deceased son. However, this is revealed to be a ruse. As a demon, Lügner is unable to experience human emotion. However, like the rest of the species, he demonstrates extreme pride in his magic and mana, even becoming furious and calling the way which Fern and Frieren suppressed their mana despicable. In addition, Lügner is exceptionally proficient at mimicking human emotion, as shown by the easy way he spins a lie to placate Graf Granat's anger about his deceased son. He is deceptive and confident in his magic and sensory capabilities.

Appearance
Lügner has long, approximately shoulder-length ash blonde hair. His hair is parted in the middle of his head, and two long strands cascade down to frame his face. His horns are medium length and protrude from the center of his head upwards. They are bent at the base and near the tip, and point upwards and forwards. Lügner, visiting Graf Granat's Domain under the pretense of being an envoy for peace, dresses in a similar style as the Graf. He wears a long, ruffled white cravat that is fastened in place by a gemstone over a dark doublet and gray pants. Lügner also wears a long, dark coat with gold trimmings and knee length white boots.

Abilities
Blood Manipulation: Lügner is able to manipulate his own blood. He can manipulate his blood for attack and defense, and can seal his own wounds and pseudo-regenerate his limbs by freezing his blood. In addition, he is able to circulate mana within his blood and use it to track enemies. Blood Manipulation: Balterie is Lügner's signature spell. When Lügner uses this spell, he forms a series of tendrils from his blood that float in the air around him. These tendrils can be used to spear his enemies, or to defend him from other spells.
