The youngest of the trio, Ai boasts a spirited, tomboyish personality and carries a genius-level IQ. She excels in mechanics, computer programming, and engineering. Ai has crafted an assortment of gadgets to assist her sisters in their heists. Despite her preoccupation with typical teenage concerns and dreams of romance, she remains highly capable. As a high school girl, she owns a pet tabby kitten named "Tiger."
Though not as skilled as her sisters in certain areas, Ai has mastered numerous abilities and frequently handles getaway vehicles for the heists. This includes operating helicopters, gyrocopters, trucks, motorcycles, cars, and mini-planes. Her main weakness is her physical strength, which is the lowest among the three siblings, as seen when she attempted a suplex on a wrestler and it backfired. However, she compensates with exceptional agility.
