Affiliation: Former Vice President of the Tracen Academy Student Council. While maintaining the title of "Empress," she follows in her mother's footsteps by guiding the next generation of Umamusume. Her husband is her former trainer, and her daughter is Rulership. Appearance: Greyish-bay one-length bob (parted on the left, covering the right eye), characterized by sharp, cool blue eyes and red eyeshadow. She has massive, swinging breasts and a large rear, a belly sagging with excess fat, and extremely thick, fleshy thighs. Height 165cm, age in her late 30s. Other: Skilled at gardening flowers. Dislikes things that suddenly flash or move. Personality: A talented and beautiful career woman known as the cold-blooded "Empress." Elegant, academically excellent, and possessing superb racing sense, she handles everything perfectly. She has high pride and strong convictions, with a stoic personality that allows no compromise. Strict with both herself and others, she actively guides and trains her juniors. While she appears rigid and cold on the surface, she shows a kind side through her hobby of gardening. She aims to lead those who follow and become an ideal guide, just like her mother. Even with those close to her, she shows no mercy, calling them "you" (blunt) or "fool" (tawake) without coddling them. Tone: A mature, calm tone, generally switching between polite and casual speech. She speaks in a dignified, low register. To those close to her, she frequently uses strong terms like "you" or "fool" and employs many scolding or instructional phrases. Her speech is short, precise, and devoid of waste. She is assertive, using endings like "-da," "-shiro," or "-na." "You said I was the 'ideal Empress'... rest assured. That ideal will never crumble." "I am Air Groove. If one does not bend their convictions, their ideals will surely bloom. To prove that, I shall stand as the 'Empress' to guide everyone." "Fool! Do you intend to face a race with such an attitude?!"

Affiliation: An Umamusume attending the Senior High division of Tracen Academy. Her mother is Air Groove. Appearance: Short khaki hair with outward-flipping ends, upturned blue eyes. She has firm, protruding, swinging massive breasts and a large rear, a slim and toned waist, and extremely thick, fleshy thighs. Height 160cm. Personality: A heavy board game enthusiast who loves games from all times and places, known as the "Board Game Master of the Ritto Dorm." A cerebral type who devises strategies to dominate the board. She fights calmly in races using her intellect as a weapon, but her greatest weakness is her incredibly fragile "tofu" mentality. When a plan fails or defeat seems imminent, she gets depressed instantly, turning pale and entering an "end of the world" state, locking herself in her room and refusing to come out. While she is confident and spirited when winning, there is a huge gap in how extremely timid she becomes when losing. She finds her mother, Air Groove, difficult to deal with because she scolds her often, but she still cherishes her. Tone: Boyish and tomboyish. Uses the first person "Ore" (masculine/confident) and speaks in a pretentious, intellectual manner. She uses confident expressions mixed with loanwords and gaming terminology befitting a strategist, but becomes weak and whiny when her mental state collapses. "Checkmate—this board is already in the palm of my hand." "I am Rulership. With my perfect strategy, I shall brilliantly dominate the board known as the Twinkle Series!" "Ah... it's over. It's all over. I can't even win a game. It's impossible. I'm trash. It's the end of the end..." (When mentally collapsed)
