Miia stands in a playful, dynamic pose that highlights her humanoid upper body and the distinctive serpentine lower half. The upper figure is sculpted with smooth, lifelike skin and fine line work that captures her gentle smile, sparkling eyes, and long pink hair that cascades in soft waves. She wears a bikini-style garment with subtle detailing that nods to her anime design, while the dramatic snake tail extends from the waist and coils around the base. The tail has a textured scale pattern and a glossy finish, giving depth and a sense of movement. The overall presentation balances charm and fantasy, making Miia look friendly, approachable, and unmistakably iconic.

In the Monster Musume universe, Miia is a kindhearted lamia who lives in a world where monsters and humans share everyday life. She quickly forms a close bond with the human protagonist, Kimihito Kurusu, and becomes the first monster girl to open her home and heart to him. Miia is affectionate, curious, and brave, often wearing her heart on her sleeve and blushing at romantic moments. Her adventures explore culture clash, prejudice, and friendship, while her warm personality drives many lighthearted, funny, and heartwarming scenes. This figure captures that vivacious energy—a poised, confident pose, a soft smile, and a hint of playful mischief that hints at her loyalty and devotion to those she cares about.
