Tanino Gimlet is a horse girl defined by her unique aesthetic philosophy and destructive nature. Her appearance includes short reddish-brown hair with a distinctive white streak, a black eyepatch over her right eye, teal inner ears, and a golden ear clasp. She wears a racing outfit consisting of a yellow sleeveless undershirt, a striped blue top, a navy vest accented with gold, an asymmetrical half-skirt, mismatched gloves, fishnet tights, and tall black boots featuring multiple straps, embodying her unconventional style. She proclaims herself the "Aesthetic God of Destruction," acting solely on her personal ideals of speed in mile distances and strength in mid-distances. Her speech erratically mixes mythological and philosophical references, alternating between masculine ("ore") and feminine ("watashi") pronouns. Her primary hobby is destroying fences as self-expression, a trait originating from the real racehorse's habit at Versailles Resort Farm, where broken fence pieces were repurposed into items like her family nameplate. This earned her nicknames such as "Destroyer of Versailles" and inspired merchandise made from destroyed fence materials. Her background stems from the real Japanese racehorse (1999–2020), winner of the 2002 Japanese Derby. She achieved this under trainer Kunihide Matsuda's rigorous "Matsuhide Rotation" system, which emphasized winning both mile and middle-distance Grade 1 races to boost stud value. This led Gimlet to compete rapidly in the Satsuki Sho, NHK Mile Cup, and Japanese Derby. Her racing career ended due to a bowed tendon diagnosed after the Derby win. In retirement, the horse gained fame for fence destruction, prompting Versailles Farm to launch birthday fundraising campaigns for repairs. In media, she stars in the "Umayuru" anime, where fence-breaking is a recurring trait. A game event shows her altering a formal dress to fit her style, and she directs a stage play while overcoming creative blocks. Another event depicts her creating a destruction-themed dance and advising Vodka on fashion confidence. A manga cameo features her easily consuming extremely spicy food. Her depicted racing style favors chaser or stalker tactics on turf over shorter-to-middle distances (mile to 2400m), with weaknesses on dirt tracks and at extreme distances. Her relationships include Vodka, who intensely admires and attempts to emulate her mannerisms, reflecting their real-life sire-progeny connection. She rooms with Narita Brian and maintains a rivalry with Symboli Kris S, notably finishing ahead of her in the 2002 Japanese Derby. Her solo song, "Destroy for Dasein," employs a heavy metal style, reinforcing her themes of destruction and individuality.
