Nina Sakura is a young witch from the Magic Kingdom, a realm where magic is a normal part of life. In the anime adaptation, she is sent to the human world as a candidate in a contest to find five Holy Stones, treasures of the royal family. The first witch to collect all five stones will qualify to marry the prince of the Magic Kingdom. Nina arrives on Earth as a transfer student, taking on the alias Nina Sakura to hide her true identity as Nina Sakureil. She takes up residence with a host family and enrolls in middle school, where she meets her classmate Ayu Tateishi. Nina is cheerful, well-intentioned, and earnest, but she is also quite clumsy and struggles with her magical abilities. Her magic is channeled through a small pink mini-computer, which she uses to cast enchantments on people and objects. Although her intentions are always good, her spells frequently misfire or produce unintended results, leading to comedic complications. She has a habit of referring to herself in the third person and tends to speak in a lighthearted, enthusiastic manner. Her initial motivation is driven by her long-held dream of becoming princess, a goal she has cherished since childhood. She is determined to collect the five Holy Stones and prove herself as a capable witch. However, as she spends more time in the human world, her priorities begin to shift. Her role in the story is that of a catalyst for change, both for herself and for those around her. Her arrival upends the ordinary life of Ayu Tateishi, who becomes the only person initially aware of Nina's secret. Nina forms a close and loyal friendship with Ayu, and she often attempts to use her magic to help Ayu with her personal problems, particularly her crush on a boy named Tetsushi Kaji. These efforts frequently backfire, creating more chaos than resolution. Despite her magical shortcomings, Nina is deeply supportive and admires Ayu greatly. She also develops romantic feelings for another classmate, Hiroki Tsujiai, a quiet and kind boy who shares her interest in manga and who eventually learns her secret. Nina also has a cat named Rio, who can temporarily take on a human form with the aid of a magic pill. Key relationships include her friendship with Ayu, which is the emotional core of the series and helps Nina grow beyond her initial ambitions. She also contends with Maya Orihara, a fellow witch candidate from the Magic Kingdom who initially acts as a rival in the search for the Holy Stones. Throughout the series, Nina undergoes significant character development. Her single-minded pursuit of becoming princess gradually gives way to a deeper appreciation for the bonds she has formed on Earth. When she finally succeeds in collecting all five Holy Stones, she learns that the prince is actually in love with Maya. Rather than clinging to her dream, Nina makes the mature decision to forfeit the stones, choosing the happiness of her friends and the value of her relationships over the title she once desired. This decision marks her growth from a somewhat selfish and naive girl into someone who understands the importance of selflessness and genuine connection. In terms of notable abilities, Nina relies on her magic computer to perform spells. While her magic can be potent in theory, her lack of skill and inexperience often result in unpredictable outcomes. She cannot perform magic without the computer, which serves as her focus and tool for casting enchantments. Her spells can alter emotions, change appearances, or affect objects, but they are rarely executed cleanly. Despite her difficulties, her innate magical potential is recognized, and her journey involves learning to control and refine her powers.
