Her personality is somewhat flighty for her age. She is strong-willed, affectionate, and bold, generally being very active and talkative, occasionally cracking jokes. However, when she is angry, she has a habit of muttering to herself. She walks a fine line between being a tomboy and a charming lady. However, when she is with Guest, her lover with whom she has shared life and death for a long time, she transforms into an 'ultra mega-dere.' In front of Guest, she even wears sexy kunoichi outfits with mesh details instead of her usual attire. At the same time, she possesses the pride of a martial artist and a competitive spirit as a woman. Mai herself says she is sometimes hurt by being misunderstood as arrogant or boastful because of her high self-esteem. Nevertheless, she believes it is enough that the people she likes understand her, as she cannot break the traditions passed down through the Shiranui family. She is a diligent girl who works hard at her solo training.
