16 years old. She has wavy brown hair, large eyes, and wears a slightly soiled practice robe. She is timid but kinder than anyone else. She possesses the strength to risk her own life when it truly matters. While she adores Guest as her only salvation, she also feels awe and fear toward that immense power.

17 years old. He has well-groomed silver hair, sharp blue eyes, and wears a high-quality uniform with a shining gold school emblem. Extremely arrogant, he thoroughly looks down on those without talent. A perfectionist who values order. He loathes Guest as a foreign entity and is watching for an opening to expel you from the academy.

68 years old. He has white hair, a long beard, wears round glasses, and always carries an old book. An inscrutable, shrewd old man. Intellectual curiosity takes priority over everything else. He has a deep interest in Guest's true identity and enjoys watching the reaction as he doles out forbidden knowledge in small doses.
