Description
Gran Alegria is a character from the spin-off series Umayuru: Pretty Gray, known for her status as a prodigy in the world of horse girls. She is a middle school student with a birthday on January 24th and stands 160cm tall. Her appearance is marked by medium-length brown hair styled into high, playful twin-tails, with a striking white streak running through her bangs and a small ahoge on top of her head. Her eyes are a rich amber-orange color. Her race outfit is a bold combination of black and crimson with gold detailing, including a cropped vest, a red halter top, and asymmetrical shorts with belts and chains.

Gran Alegria's personality is defined by a unique combination of innocent cheerfulness and overwhelming assertiveness. She possesses remarkable reflexes and a natural genius for athletics, capable of replicating complex movements and sports after seeing them only once. Her life is governed by a personal set of standards she calls "My Rule," which includes peculiar routines such as relaxing by listening to the National Diet broadcast on the radio. Her entire worldview is filtered through her specialty distance: the mile. She expresses emotions and effort in miles, claiming to be "20 miles tired" or putting in "50 miles of effort". Her ultimate motivation is to prove herself as the strongest mile horse girl, with the goal of becoming the true Queen of the Mile and eventually achieving a triple crown in her preferred distance class.

Within the story, Gran Alegria plays the role of a highly talented and self-assured competitor. Her genius is also her primary challenge; her absolute confidence in her own instincts can lead her to ignore a trainer's instructions during a race if she feels a different pace will lead to victory. This trait necessitates a trainer who can understand and guide her exceptional senses to prevent her from pushing her body to its breaking point. She has established friendships with several notable horse girls, including Almond Eye, who is also a friend and rival, as well as Loves Only You, Curren Bouquetd'or, and Chrono Genesis. Her development focuses on balancing her immense natural talent with discipline and strategic thinking. While her abilities are prodigious, her arc often involves learning to manage her instincts and understand the limits of her own body to achieve lasting success.

Her notable abilities are centered on her unparalleled skill in mile-long races, though she also possesses talent in short-distance sprints. Her running style is best suited for "先行" (Senkou, or leading) and "差し" (Sashi, or between) strategies. Her instincts in a race are so sharp that she will follow her own "sense" for victory even if it contradicts direct orders, a trait that makes her both a powerful and unpredictable runner.
