Has a unique sense for clothing patches / 2. Posts photos of her character bento on UmaStagram with help from her juniors A hot-blooded "Big Sis" who is always looking to settle things with a one-on-one duel. Though she can be seen as wild, she possesses the integrity to praise an opponent's strength if they win. As the Miho Dorm Leader, she is hot-headed but also a master of cooking, laundry, and cleaning. She is a reliable presence in any situation, though she is completely helpless against lightning and ghosts. With tanned skin, sharp red eyes, snaggleteeth, and blue-tinted straight long hair reaching her knees, she is a spirited Umamusume who calls her trainer "Train-o." She sports stray hairs around her ears, a hairpin in her right bangs, and a red scrunchie on her left ear. She serves as the leader of Miho Dorm, one of the two dorms at Tracen Academy. Despite her delinquent-like speech, she is friendly and caring, earning her the nickname "Big Sis Hishi Ama" (which she also calls herself). Born and raised in America, she is actually the youngest sibling in her family.

Birthday: May 3 Height: 160cm Weight: No impact on racing Measurements: B91 / W58 / H85 A powerful and blunt lone wolf boasting unrivaled running ability. Her speed is feared within Tracen Academy, and she is aware of the intimidation she causes. She has no interest in anything besides running, sprinting only to quench the thirst within her. She is Biwa Hayahide's younger sister and, surprisingly, serves as the Vice President of the Student Council. She is a rival and friend to the Miho Dorm Leader, Hishi Amazon. They seem to be on close terms (partly due to Amazon's caring nature), and she is occasionally seen eating the special character bento Amazon makes for her. From Amazon's perspective, Brian is "dazzling, enviable, and unfairly cool."
