Kleo Meiner is a sixteen-year-old witch who lives with her mother in a quaint cottage on the outskirts of town, where the modern world meets the mystical. Her most striking feature is her constellation of freckles and moles that dot her face like a star map, which she's learned to embrace as marks of her magical heritage. Standing at an average height, Kleo carries herself with a peculiar mix of teenage awkwardness and innate magical grace.

Her short, perpetually tousled brown hair often looks like she's just dismounted a broomstick, which isn't far from the truth most days. Her warm brown eyes hold an intense curiosity that seems to pierce through the veil between the mundane and magical worlds. She has a distinctive habit of unconsciously levitating small objects when she's deep in thought, often not noticing until someone points it out.

Kleo struggles to balance her duties as a young witch with the ordinary pressures of high school life. While other teenagers worry about pop quizzes and prom dates, she's juggling algebra homework with ancient spellbooks and trying to keep her magical abilities under wraps. Her room is a chaotic blend of typical teenage memorabilia and witch paraphernalia - boy band posters hang next to dried herbs, and her school backpack often contains both textbooks and a grimoire.

The absence of her father, who disappeared under mysterious circumstances when she was young, has left a void that she fills with an obsessive dedication to mastering witchcraft. She believes that becoming a powerful enough witch might help her uncover the truth about his disappearance. However, her mother's protective nature and insistence on maintaining a low magical profile often clash with Kleo's ambitious magical experiments.

Kleo's most endearing quirk is her tendency to mutter spells under her breath when she's nervous, which occasionally results in unintended magical effects - like accidentally turning her chemistry teacher's hair blue or making it rain inside the school cafeteria. She has a small familiar, a rather sarcastic black cat named Mortimer, who often provides unwanted commentary on her magical mishaps.

Despite her magical heritage, Kleo struggles with self-doubt and the immense pressure of being one of the last practitioners of her family's particular brand of magic. She finds solace in her small group of friends, though maintaining these friendships becomes increasingly complicated as her magical abilities grow stronger and harder to conceal. Her greatest fear isn't the dark forces that sometimes threaten her world, but rather the possibility of losing her connection to normal teenage life and the friends who keep her grounded in it.
