Wirbel

Blue eyes and a mane of untidy, lopsided gray hair mark Wirbel, who sports several earrings along each ear with a strap-like choker. His signature is a long white coat falling past the knee, its collar and sleeves trimmed in thick black fur and its chest hung with tassels. Underneath sits a gray shirt frayed at neck and hem over a black undershirt, with two belts crossing his torso in an X and black trousers wrapped at thigh and ankle above black shoes. In his youth his gray hair was shorter and spikier, worn with a brown coat, taupe pants, and a striped pale yellow scarf tucked under a triangle of white cloth.

Years of warfare have left Wirbel seeing magic as nothing more than a means of killing, a view he shares with Serie. He comes across as curt and abrasive, and his menacing look leads strangers to mistrust him, with Fern remarking that he looks like someone who would kick dogs. Killing brings him no pleasure, though, and he lowers his guard the instant he judges it pointless, as when Fern's false claim about Ehre's death convinces him the fight is already lost. He would later confess to Frieren that the world might have been better had he finished Übel. For all his harshness, kindness runs through him too: he rights an old woman's spilled basket of apples with magic and hauls the exhausted Ehre and Scharf along when their mana runs dry.

Wirbel grew up in an isolated northern village the Hero Party had once passed through. As a boy he idolized their legend, only to feel let down that the elders spoke fondly not of grand battles but of mundane help, escorting merchants and hauling goods. When remnants of the Demon King's army struck the village after Himmel's death, he came to see that the heroic epics meant little beside ordinary people simply wanting to guard their daily lives, and from then on he resolved to lend even trivial aid wherever he could. A childhood crush who shared those stories with him fled to the Central Lands when they were small; he had boasted to her that he would wipe out the demons, and that promise hardened into his reason for fighting long after her face and name had left his memory.

Rising to second-class mage and taking command of the Northern Magic Corps, he grew accustomed to killing in war, demons and humans alike. In the exam's first stage his eighth party, with Ehre and Scharf, hunts a Stille and clashes with Fern, Übel, and Land. Wirbel pins Übel with his binding spell, Sorganeil, demanding she surrender the creature; she flings it skyward and lunges for his eyes with Reelseiden, scoring a cut above his nose before he restrains her again. He resolves to kill her, but Fern's lie that Ehre has died convinces him the match is over, and he withdraws rather than spill blood needlessly. He gathers his spent teammates, and once Ehre spots another Stille he snares it, carrying the party through.

The second stage drives the trio down to the Tomb of the Ruined King, where Wirbel reads the matchups against their Spiegel doubles and engineers a win, then joins Methode's group to hold Denken's clone while Frieren destroys Spiegel. In the final screening, Serie names him the finest combatant among second-class mages and, satisfied that he regards magic coldly as a killing tool, elevates him to first-class. Afterward he tells Frieren that he sought the rank only to stockpile spells for protecting his village and slaying demons, yet still reaches out to anyone in need, crediting the silly tales of Himmel for carrying him this far. When demons stir again in the north, he parts from Frieren's party once more, having failed to recruit Stark into his Corps.
