Yuria, an extraterrestrial humanoid with feline features, sports fiery red hair and striking emerald green eyes, accentuated by a curvaceous silhouette. She lands on Earth as a member of an alien delegation tasked with conducting intimate studies of human behavior, particularly sexual practices. Her mission centers on direct, hands-on engagement, guided by Shinji, a college student she meets immediately upon arrival. Their collaboration forms the foundation of her exploratory efforts to decode human customs.

She shares a sisterly bond with Alissa, a fellow alien who later reinforces their mission on Earth. Together, they pursue cultural and biological research objectives, though their homeworld’s specifics and the full scope of their assignment remain undisclosed.

Yuria’s narrative unfolds exclusively through her dynamic with Shinji and Alissa, with no extensions or alterations in other media. Her physical traits—feline attributes, vivid hair, and eye color—and her inquisitive, methodical approach to human interactions persist uniformly across all documented appearances, maintaining continuity without deviation.
