Symboli Rudolf

She is a student at Tracen Academy, serving as the school's student council president. In the Pretty Derby anime, she is a member of Team Rigil training under Hana Toujou.

Known as the "Emperor," she is one of Japan's leading umamusume.

Well-versed in both the ways of racing and leadership through her work leading the student body, she serves as the evenhanded president of the student council at Tracen Academy. She seeks to be a model Umamusume, and as such, is keenly aware of the example that she sets. Her dream is to foster a new era in which all Umamusume can live in true happiness. She is especially admired by Tokai Teio.

Symboli Rudolf has light brown hair that reaches below her waist, with the front of her hair being dark brown. And two large strands of hair lay on either side of her shoulders. On each side of her bangs, a large strand of hair reaches down and loosely frames her face, with the center of her bangs being a patch of hair. And a cream white streak of hair is curved to the left side of her face, that starts in the left side of her bangs. Her horse ears have slight fluff on the sides, with the tips fading to a dark brown. Her right horse ear has a large teal crystal, silver frame ear ring on the right side of the base of her ear. Her eyes are a light magenta.

Her attire commands both respect and awe, embodying the militaristic style and color scheme of the Symboli family. She dons a dark green jacket adorned with numerous medals of achievement, with silver buttons lined up in perfect uniformity. An epaulet graces her left shoulder, complemented by a flowing red cape that adds to her imperial presence. The sleeves are embellished with golden patterns and unique markings, a variation of the designs seen throughout the Symboli family. To further continue the Symboli lineage, she wears a large custom belt with a prominent silver centerpiece.

Downwards, she wears a dark green skirt with elegant ruffled hems. Her black tights feature the same gold patterns found on her sleeves and her outfit is complete with black buckled heels.
