Tisalia Scythia is a centaur distinguished by her striking gold hair and blue eyes. Her human half is slim yet voluptuous, while her equine half is notably larger, more muscular, and covered in black fur compared to typical centaurs, creating an imposing figure. She favors elaborate attire: a dress featuring a ruffled collar, puffy sleeves, wrist guards, and a pleated skirt.

Her personality blends pronounced pride with a direct, hardworking nature. She openly voices her desires and takes significant vanity in her beauty and physique, reacting strongly to any perceived insult about her appearance. Despite her noble standing, she actively engages in strenuous manual labor like intensive arena training and personally pulling carriages. She exhibits minimal modesty, freely displaying her body when confident it will draw attention. Her pursuit of romantic interests is unabashed and persistent.

As the sole heiress of the influential Scythia family, her background involves substantial contributions to Lindworm's prosperity through their transportation business. She works professionally as a successful arena combatant, leveraging her heritage and physical capabilities for consistent victories.

Her primary relationship centers on Glenn Litbeit, whom she openly pursues for marriage, leading to a friendly rivalry with Saphentite Neikes. By the conclusion of the light novel's sixth volume, she formally becomes Glenn's fiancée, though their marriage awaits his achievement of financial independence for his clinic.

Her abilities capitalize on her centaur physiology, granting exceptional strength and endurance, demonstrated by single-handedly pulling a loaded carriage up a mountain. She specializes in javelin combat, using powerful charging attacks to incapacitate opponents swiftly. She also exhibits strong leadership, effectively organizing evacuations and mobilizing allies during crises.

A key weakness is her pride, particularly concerning her noble lineage and combat reputation. She can become skittish or fearful when startled or confronted with unexpected situations, such as mistaking benign objects for evidence of violence.

Her development includes advancing her romantic relationship with Glenn to a formal engagement and demonstrating increased responsibility through crisis management. Her consistent arena victories and proactive role in community safety cement her status as a capable leader beyond her initial portrayal as a determined suitor.
