Kisugi, Ai

来生愛

As the youngest of the trio, Ai possesses a spunky, tomboyish personality and demeanor, along with a genius-level I.Q. She is particularly adept at mechanics, computer programming, and engineering. She has constructed a wide array of gadgets to assist her sisters during their heists. Like a typical teenager, she appears to be frequently preoccupied and dreams of falling in love. As a high school student, she also owns a pet tabby kitten named "Tiger."
Although not as skilled as her sisters, Ai has nonetheless mastered several skills and regularly operates the getaway vehicles for the heists, including helicopters, gyrocopters, trucks, motorcycles, cars, and mini-planes. Her greatest weakness is that she is physically the weakest of the three siblings (as seen in the anime when she attempted to suplex a wrestler, only for the maneuver to backfire on her), but in return, she is also the most agile.
