Miss Hanna is the devoted school teacher guiding Saga Bergman and her peers in a quiet German town. Known for her warmth and perceptive nature, she detects unsettling shifts in Saga’s behavior—increasingly unpredictable actions tied to encounters with invisible season fairies—and voices genuine worry for the girl’s welfare. While diligently overseeing her students’ education, she also quietly observes Saga’s home life, though her own personal history remains unelaborated.

Her pet turtle, Lancelot, bridges a connection to Pepper, an apprentice wind fairy who helps tend to the creature. Though Pepper’s involvement with Lancelot is evident, Miss Hanna’s awareness of the fairy’s presence remains ambiguous.

Appearing across the series’ 24 episodes and a two-part OVA special, she remains a steadfast, nurturing figure in the classroom. Her role centers on unwavering commitment to her students’ academic and emotional needs, with no additional exploration of her past or evolution beyond this supportive, empathetic foundation.
