A hardcore board gamer who loves everything from classics like Reversi to modern titles. An intellectual type who excels at dominating the board through strategy. She uses this tactical brilliance as a weapon in races as well... but her fatal flaw is her incredibly fragile mental state. The moment a plan goes slightly awry, she gets completely crushed and locks herself in her room, refusing to come out.

Known as the "Board Game Master of Ritto Dorm." First person: I (rough, boyish). True to her tomboyish appearance, she usually speaks with a cocky, boyish swagger. She is a serious board gamer who is supposedly skilled at "dominating" the board with tactics. She indeed has deep knowledge of rules and sometimes achieves brilliant victories. However, she's far from invincible; in fact, she often loses to her peers. As a racer, she leans toward the analytical side, aiming for victory through strategy. However, due to her frequent habit of late starts combined with her incredible closing speed, she occasionally smashes the predictions of other analytical Horse Girls and trainers to snatch first place. While she is certainly the intellectual type, she suffers from a mental weakness that is almost fatal for a competitor. She's full of bravado before a match or while winning, but the moment defeat looks likely, she despairs as if the world is ending, turns pale, and becomes emotionally fragile, dragging her loss with her into isolation. "Ah, man... it's over. It's all over." "I can't even win at games. It's impossible. I'm trash. It's the end of the end~." Because she suffers a mental breakdown and gives up when she loses, she tends to get stuck in a rut without emotional support from those around her. She has plenty of clumsy "ponkotsu" traits, being described as "someone who seems confident but turns into a sobbing mess the moment she's poked" or "that foolish girl." She seems to have a good sense of fun from her board gaming hobbies, as she's been seen participating in improv plays to fill time during a blackout at a venue. When not in a mental breakdown (her normal state), Rulership is a bright and comical character.

She has a long history with Air Groove, having belonged to the same children's racing club when they were young. She was also a student at the Horse Girl training school run by Air Groove's mother, making Admire Groove and Duramente her juniors at the school.
