Lügner

Lügner keeps his ash-blonde hair at roughly shoulder length, split down the middle so a pair of long locks spill forward past his face. From the crown of his head rise two horns of moderate size, kinked at the root and again near their points, angling up and ahead. To sell his role as a peace envoy he mirrors Graf Granat's manner of dress: a frilled white cravat pinned with a jewel at the collar, a dark doublet, gray trousers, a gold-trimmed overcoat, and white boots that climb to the knee.

On the surface Lügner reads as serene, unhurried, and understanding, shrugging off Frieren's attack and commiserating with Graf Granat over the man's dead son. All of it is performance. Like every demon he feels no genuine human emotion and only imitates it, a skill he wields well enough to talk a grieving count out of his anger. What he does feel is enormous pride in his craft; the way Frieren and Fern throttle their own mana strikes him as contemptible, and the discovery sends him into a rage. He is a deceiver who trusts his magic and his senses completely.

Aura the Guillotine dispatches Lügner alongside Linie and Draht under a flag of truce, and Graf Granat admits the trio past his city's barrier. The count, who lost a son to demons, springs a trap and draws that son's blade, but Lügner improvises a tale of his own murdered father and a wish to end pointless killing, stalling Granat into reconsidering. Once Draht falls to Frieren and Granat catches Lügner in a second lie, the demon drops the act, slaughters the guards with his blood, runs the count through, and binds him, demanding the secret to lowering Flamme's millennium-old barrier that he so resents.

The plan unravels from there. Stark stalls him until Fern lands a Zoltraak through his chest, a shock to Lügner since demons had figured out generations ago how to weather it, not realizing Fern's version was reworked to slay them. He heals, hunts the pair using his own blood left on their clothes, and pins Fern to a tower to interrogate her. Their duel turns into his signature blood manipulation, Balterie, against her relentless speed; though he boasts superior mana, finer technique, and tighter control, her flurries crack his defenses faster than he can wear her down. When Linie dies and his attention slips, Fern drives a final spell through his heart. Dying, he insists Aura will outlast Frieren, only to grasp at the end that both women constantly suppress their mana, a tactic he condemns as a disgrace before Fern finishes him.
