Episode 18

The party arrives at Äußerst, the north's greatest magical city, where Frieren urges Fern to pursue the first-class title she herself finds pointless. Frieren warns that mana alone never decides a mage's strength, citing the eleven times weaker-mana opponents have beaten her, among them four demons including Qual, one elf, and six humans. Elsewhere, a mage named Übel is saved from bandits by Kraft, who reads the killer's instinct in her eyes as she heads to the same exam.

Registration nearly stalls because Frieren holds no modern certification, until an elderly mage recognizes her antique Holy Emblem and admits her. A flashback shows the Hero Party failing to place the same emblem, with Himmel reassuring her that they knew her worth regardless. In the present, Fern offers the same reassurance. Research reveals roughly two thousand mages exist, only six hundred ranked fifth-class or above, and a mere forty-five holding first-class status.

The proctor Genau opens the exam, warning that the association will not protect failing candidates. The fifty-seven examinees are sorted into trios by enchanted bracelets. Frieren draws two squabbling young mages, Kanne and Lawine, while Fern is grouped with Übel and a bespectacled mage named Land. The first stage demands each party cage a Stille, a bird that flies past the speed of sound, shrugs off ordinary spells, and carries almost no detectable mana.

Kanne and Lawine's coordinated attempt to trap one fails against its toughness and speed. That night a Geisel bird monster ambushes Kanne, and Frieren subdues it, having warned her to watch the sky. Sharing a quiet moment, Kanne explains how the harsh but reliable Lawine once forced her to fly, and reveals she has noticed something useful about the Stille.

Frieren reaches Äußerst and registers for the exam only when her old Holy Emblem is recognized. Research establishes how rare the forty-five first-class mages are. Übel is introduced, rescued from bandits by Kraft.

Proctor Genau sorts fifty-seven examinees into trios for a first stage requiring each to cage a Stille, a near-untouchable bird. Frieren is paired with the quarrelsome Kanne and Lawine, and Fern with Übel and Land. After a Geisel monster ambushes Kanne, Frieren saves her, and Kanne spots a clue about catching the Stille.

Frieren's flashback to the Einsam, shown in the manga when she explains the Northern Plateau's dangers, is omitted from the anime. Kraft's clash with the bandits is expanded so he fights all three rather than only their leader. The library where Frieren and Fern study is presented as part of the magic association's branch building rather than a separate structure.

The anime adds a moment of the female observer reacting uneasily to Übel's gaze and shows four parties with empty cages after Genau's briefing, where the manga showed three beforehand. Kanne's later talk with Frieren is staged on the cliff where she was attacked instead of on the walk back to camp.
