She is voiced by Jenny Baker in OVA and Julie Ann Taylor in X (TV Show).
In Tokyo Babylon, Hokuto was about 16 years old. She had straight black hair that fell to her ears and very green eyes. While she lacks most of Subaru's strong spiritualistic abilities, she is still able to cast spells unique to her. She always means well and acts in Subaru's best interests. Hokuto is the designer of the outrageous outfits she and Subaru often don. Hokuto feeling guilty for her promotion of Seishirō, whom she knew to be dangerous, but also believed to be the only one who might touch Subaru's heart, leaves to find Seishirō and confronts him, asking to be killed by him and casting a spell with her death.
She is quick-witted, bold and impulsive, the polar opposite of Subaru. She was upset when she was saying Subaru goodbye. She was crying, because she knew that she wouldn't see him again. She made a choice, was determined to save him.
