Princess Sparkle, known in Japanese as Supākuru Hime, is a character from the anime Spider Riders: Yomigaeru Taiyou. She is a young child with short orange hair that reaches her ears and purple eyes. She is the princess of the Arachna Kingdom and the younger sister of Prince Lumen.

Though she holds the title of Spider Rider, she is still very young and does not take part in combat. When she tries to join a fight, Grasshop, the Grasshopper Invector, stops her and tells her she cannot. Her partner Spider is Hotara, and the two share a very close relationship. She affectionately calls Grasshop "Batta no Ojichan," which means Grasshopper Uncle, and is deeply attached to him. Her transformation phrase is "Oracle no Junshin yo," which draws on the purity of the Oracle.

Her personality is marked by youthful warmth and a strong attachment to the people around her, especially Grasshop and Hotara. Her willingness to attempt battle despite her age shows a brave and spirited nature, though the older warriors around her keep her out of danger. As a princess, her role in the story is that of a protected member of the royal family, supporting the other Spider Riders from a distance while remaining connected to the central conflict through her brother and her companions. Her main motivation is her desire to help protect her kingdom and take part in the fight alongside the other Spider Riders, even though she is not yet old enough to do so. In terms of abilities, she is capable of performing the Spider Rider transformation through the power of the Oracle and maintains a strong partnership with her Spider, Hotara.
