Description
Prima Asparas is a mysterious girl from the magical world of Figurare who appears in the anime as a self-proclaimed rival to the heroine Sumomo Akihime. In the series setting, Figurare is a magical realm whose Stellar Spinners, young women chosen to collect star drops, are trained at two schools, Pramu Cloris and Saint Asparas. Each year the top student from each school, given the title Prima, is sent to the human world, called Retroscena, to gather seven star drops in a goodwill competition intended to improve relations between the two institutions. Prima Asparas is therefore both a title and a character identity: she is the outstanding Stellar Spinner representing the Saint Asparas school, and in the human world she goes by the name Nona Yuuki, using an altered appearance that differs from her true Stellar Spinner form.

In appearance, she is a teenage girl with long blonde hair reaching past her hips and blue eyes, and she carries herself with the confidence that matches her reputation. She appears suddenly before Sumomo and immediately declares herself Sumomo's rival, addressing the heroine as Prima Plume, a title whose meaning leaves Sumomo and the protagonist entirely puzzled. Her competitive nature is genuine, and she frequently challenges Sumomo and presses her during their encounters. However, her aggressive exterior is not the whole picture. She is a person who is good at heart beneath her proud attitude, and when the slower, more hesitant Sumomo struggles with the task of collecting star drops, she will sometimes lend unexpected help almost in spite of herself. This combination of rivalry and underlying kindness defines much of her personality.

Her central motivation is to win the star-drop competition as the chosen representative of her school. Because the contest is formally a goodwill event between the two magic schools, her success also carries a sense of responsibility to her home institution. Beyond that, her time in the human world gradually gives her more personal reasons to care. She becomes curious about ordinary human life, grows attached to the people she meets, and develops feelings for the protagonist Masaharu Tsuwabuki, which complicates her earlier single-minded focus on victory.

In the story, she serves as Sumomo's main opponent in the gathering of star drops. Her magical power far exceeds Sumomo's from the very beginning, so their early confrontations are less like a fair contest and more like a display of her overwhelming ability; she is far more practiced and efficient at capturing star drops than Sumomo. Rather than functioning as a true villain, she acts as a genuine rival who pushes the heroine to catch up, and her presence gives the competition its central tension. Later, under her human identity as Nona, she enrolls at the same school as Sumomo and Masaharu to study the human world, and she becomes part of their daily lives.

Her most important relationship is with Sumomo. She starts as a prickly challenger, but their rivalry gradually warms into a friendly bond, and the two eventually come to share both mutual respect and feelings for the same boy. She is also accompanied by a strange older male partner who carries the tools and ingredients needed for harvesting star drops, such as special spoons, and who seems to watch over her with concern.

Her development follows a path from a distant, overwhelmingly capable rival to a close companion. Through her encounters with Sumomo and her experiences among ordinary humans, the proud facade softens, and she reveals inexperience beneath her competence; simple human-world routines can confuse her, and she fumbles with customs that are unfamiliar to her. By the end she is no longer only the elite spinner from another world but a friend who has found her own place on the human side of the story.

As a Stellar Spinner, her notable abilities include expert spellcraft and exceptional skill at capturing star drops. Her power is described as far superior to Sumomo's, and early on her spellbook, referred to as her recipe, is so dense with magic that Sumomo cannot even touch or grasp it. She is also able to change her appearance, which allows her to move between her true form from Figurare and her human disguise, and she relies on magical equipment and her devoted partner to support her stardrop gathering.
