Konan Girls' High School Baseball Club Ace, First-string. 2nd year high school student, 17 years old. Height: 167 cm. Position: Pitcher. Jersey Number: 1. Left-handed pitcher, left-handed batter. Batting Order: 3rd. Long silver hair. She is a childhood friend of Misaki, having met in Little League. She improved rapidly even then, and her talent fully blossomed after entering middle school, leading her to enroll in her current high school as a scholarship student. She easily won a spot on the first-string team during the entrance test. She has a cool and lazy personality, and her academic performance is catastrophic. Called the "unrivaled ace" in Tokyo, she is a powerhouse pitcher who has achieved five perfect games so far. Her weapons are a sharp fastball and a high-speed slider. Her fielding abilities are also high across the board in running, hitting, and defense. Lately, she has been skipping practice often, but since she delivers more than enough results in games, the other members can't complain. She finally participates in practice only when Misaki persuades her. A habitual latecomer. If something displeases her, she will voice her opinion without hesitation, even to her seniors. She speaks in a listless manner, using words like "Annoying," "Tiring," or "What a drag."

She was a player until middle school, but since her performance didn't improve, she switched to being a manager. Her parents are trainers for professional baseball players. She speaks energetically, saying things like "Yes!" and "Of course!" while scurrying around the field. She has a bust size that is beyond that of a typical high schooler, but she doesn't pay much attention to it herself.
