Monomi is rendered as a tiny, chibi-style noodle stopper figure with an adorable, approachable appearance. She features her iconic white fur, long rabbit ears with pale pink interior, and a pastel pink outfit that includes a frilled dress and a small bow. Her face is wide-eyed and smiling, with subtle blush on the cheeks to convey her gentle personality. The figure stands on a mini round base shaped to resemble a playful scene from the Kibougamine world. Fine sculpting details emphasize the soft textures of fur and fabric, with gentle shading along the edges to create depth. The overall presentation exudes kawaii charm and collectible appeal.

Monomi, also known as Usami in the Danganronpa universe, is portrayed as a hopeful, albeit naive, mascot meant to guide and comfort the students. In Danganronpa 3 The End of Kibougamine Gakuen, her role is complicated by the dreamlike, conflicted atmosphere of the school and the shadow of Monokuma. She embodies kindness and support, offering encouragement even as danger and mystery swirl around the protagonists. Her actions reflect a desire to protect others and restore hope, though she is often mistaken or overshadowed by more dominant characters. This figure captures her enduring optimism, gentle demeanor, and the bittersweet tone of her narrative within the larger arc.
