Lotte is a supporting character in the anime Izetta: The Last Witch. She serves as a maid in the royal palace of the Duchy of Eylstadt, initially assigned to attend to the Archduchess Ortfiné Fredericka von Eylstadt, known as Finé. When the last witch, Izetta, arrives at the palace, Finé orders Lotte to be of service to her directly. Lotte is a young, energetic, and cheerful girl with bright red hair. She performs her duties with a gentle diligence that puts those around her at ease, and she is known for her unwavering dedication to her work. Her practical nature is highlighted by a distinctive habit: while on chamber duties, she carries a footstool strapped to her back to help her reach higher surfaces when assisting taller individuals.

Lotte's primary motivation is her loyalty to her superiors and her deep gratitude toward Izetta. She holds sincere appreciation for Izetta protecting Finé and for helping Lotte's own family survive the chaos of the battlefield. As a result, she is committed to making Izetta feel welcome and comfortable within the palace. Her role in the story is to provide a sense of normalcy and domestic warmth amid the escalating war with Germania. She acts as a bridge between Izetta's sheltered, nomadic upbringing and the expectations of Eylstadtian court life, teaching Izetta about local customs and cuisine. One of her most notable gestures of kindness is her famous cherry pie, a symbol of comfort and hospitality that she offers to friends and guests. Her presence serves to humanize the larger conflict by showing the perspective of common citizens.

Lotte forms a close, sisterly bond with Izetta. She becomes one of Izetta's most trusted confidantes within the palace, offering emotional support and a safe, friendly presence as the war grows increasingly grim. She maintains a professional and respectful relationship with Archduchess Finé, though her primary focus remains on Izetta's well-being. Unlike the soldiers and commanders around her, Lotte does not participate in combat. Her development is subtle: she begins as a simple domestic servant and grows into a confidante and a source of hope and home for Izetta throughout the war. Her notable abilities are not magical or martial; instead, they are her domestic skills, her cheerful resilience, and her capacity to provide warmth and stability in a time of crisis. She remains cheerful and energetic despite the ongoing war, and her optimism helps to lift the spirits of those around her.
