Chapter 75: Erilfrachte, The Spell to Dispel Fog

As the night's other fights play out, Fern trades blows with a demon whose fog swallows the woodland. Frieren peels off to watch from a safe remove, which leaves the apprentice unsettled and annoyed. Concealment is hopeless, the demon says, because his mist seizes on the faintest thread of mana and nothing alive can wholly bury its own. Fern shifts to the attack with a Zoltraak, yet the demon bats it down, and she admits the blinding haze makes for an ugly matchup.

Nearby, Methode squares off with a katana-bearing demon of plain, solid technique who unleashes the whirlwind spell Medrozobalt. Finding no gap to exploit, Methode judges the wiser course is to lift the fog and hand Fern her range. She turns aggressive, hammering the demon with Zoltraak and landing one point-blank from behind. The demon observes that Methode fights like a clan of demon hunters out of the Northern Plateau, then catches that the assault holds no killing intent. Methode grants the read but calls it tardy, the mist already mapped, and casts Erilfrachte to rip the dome open.

The fog handler wavers as his shroud thins and means to spin up more, only to lose Fern and drop to her Zoltraak. The swordswoman, still bearing down on Methode, must twist away from a strike out of nowhere, spots Fern at an absurd distance, and falls to the same magic. Frieren coasts over to Fern, observing that a shot loosed beyond detection range cannot be traced, and offers praise, while Fern says she never wants a fight this brutal again.

Fern duels the fog-controlling demon as Methode takes on the katana wielder. Methode maps and then banishes the mist with Erilfrachte, handing Fern back her line of sight. From beyond the demons' detection range, Fern drops both with long-distance Zoltraak fire, closing out the clash.

Neither demon earns a name in the manga's pages, and the anime supplies only part of what is missing: the official website later lists the fog handler as Hemmung and the katana user as Solide, revealed when the matching second-season episodes ran. The mist itself springs from the spell Nebeladora.
