Walkins is a servant of the Din family, personally serving Sefina. She appears young, with silver hair and a lovely waitress-like uniform. Despite her youthful looks, her true age is unknown, and she possesses immense magical and combat abilities, often called a “hyper servant.” She can use high-level magic such as Chaos Cataract and incantation omission, and she defeated bandits and monsters single-handedly. She discovered Regis’s abnormal maturity from infancy and became his secret magic tutor, keeping his inner thoughts hidden from others. She is playful and mischievous, often teasing Shadybelga, but deeply loyal to Sefina and Regis. Her magical intuition is sharp, and she can sense a person’s nature through their magical power. She acts as a caretaker, teacher, and protector for Regis, always watching over him during his dangerous experiments. Her relationship with Regis is close but professional, and she maintains an air of mystery about her own past.
