Garack Gazelt serves as Chief Court Pharmacist at Wistal Castle, the primary pharmacist for Clarines' royal family. She possesses blond hair styled in a half ponytail bun and deep purple eyes, typically dressed in a white lab coat and accessorized with long pale red earrings featuring a darker red stripe near the bottom.

Her laid-back and eccentric nature often shifts between humorous and demanding tones, yet she exhibits profound skill in pharmacy and genuine care for her subordinates, especially Shirayuki and Ryuu. She employs unconventional methods, such as throwing darts at a map to select medicinal collection sites. Professionally, she oversees research and projects in the castle's pharmacy and assigns missions to her staff. Her expertise is renowned even in distant kingdoms like Lyrias, where her visit is eagerly anticipated.

Garack maintains significant relationships within the court. She mentors Ryuu, acknowledging his talents early and showing concern for his health, growth, and social development, supporting Prince Izana's decision to send him to Lilias for experience. She supervises Shirayuki as an apprentice court herbalist, expressing amusement at her problem-solving skills but disapproval of reckless actions. Her history with Shidan is marked by arguments and professional rivalry; they once worked together, and she invited him to the palace, though he declined. Rumors about their personal relationship persist, including an incident where Shidan attempted to kiss her while she slept but refrained. She also shares a friendly, drinking-based relationship with Obi due to their mutual high alcohol tolerance, often spending time together in the pharmacy.

She rarely speaks of her personal history, though she enjoys discussing the history of Clarines.
