Ricotta Elmar is the exceptionally intelligent and technically skilled Chief Researcher of the Biscotti Republic's National Research School, holding this position despite being approximately 13 years old. She possesses long orange hair, brown eyes, distinctive pointy orange ears, and a fluffy tail that wags when excited. While her specific species is unidentified, her fox-like traits connect her to Biscotti's animal characteristics. Her typical attire includes a white collared shirt (sometimes depicted short-sleeved), a beige vest, a red skirt, a red ribbon beneath her collar, a long white cape, and brown shoes.

Ricotta displays high intelligence and a friendly demeanor. Her intense curiosity drives her to prioritize analyzing unfamiliar machinery or phenomena, often manifesting as a desire to disassemble objects to understand them. She frequently ends her speech with "~de arimasu." Fond of physical affection, especially being stroked, she also maintains a significant appreciation for sweet foods, justifying them as necessary energy for mental exertion. She exhibits warmth and enthusiasm but experiences profound distress when confronted with complex problems, like the conditions preventing Shinku Izumi's return home.

Remarkable achievements mark her background from a young age; she designed and constructed a functional telecommunications system implemented across Flonyard at just five years old. This accomplishment contributed to her appointments as Chief Researcher and Chief Engineer at the Biscotti National Research Academy. Leading the Academy's project to research methods for returning summoned heroes to their original worlds, particularly Shinku Izumi, becomes central to her character, driving significant emotional moments when solutions prove elusive.

Ricotta maintains positive relationships with numerous characters, especially within the Biscotti Knights. She shares a close friendship with Princess Millhiore F. Biscotti and Yukikaze Panettone, collaborating with Yukikaze on combat techniques like the Profuse Hundred Blossom attack. Her interactions with Shinku Izumi deepen through her work on his predicament, showing strong attachment that occasionally suggests romantic interest. This is evidenced by her emotional reactions to challenges involving his return and her appreciation for his gifts—a four-color ballpoint pen and portable speakers—which she vows never to disassemble despite her typical inclinations.

In combat, she functions as a gunner using specialized small-scale firearms and energy batteries. Her role also includes providing crucial technological support and strategic analysis during conflicts. Her development balances intellectual prowess with emotional vulnerability, underscored by her persistent efforts to resolve the summoning mechanics affecting the heroes.
