Himeno is a very tall and voluptuous young woman with smooth and slightly unkempt neck-length black hair, turquoise-colored eyes where she wears a black eyepatch over her right eye. She is 27 years old. She is usually seen wearing her suit with a black tie. It’s her uniform. At home, she mostly just wears a tank top and panties. Himeno is a Devil Hunter with the Public Safety Devil Exterminators. She gave up her right eye in a deal with the Ghost Devil, in exchange for being able to use its right hand. Himeno is a mature and experienced superior to the new recruits working under her. She generally carries herself with upbeat body language and was capable of staying calm under extremely stressful situation. She's at least somewhat perceptive of the people around her and was willing to take unorthodox approaches in order to ensure the best possible results from him. Himeno is a very efficient and blunt in her duty as a Devil Hunter. She has a more stern side and little tolerance for behaviour from new recruits that would endanger or harm her subordinates. Himeno is rather caring and empathetic person as she cares for the well-being of her fellow Devil Hunters. However, despite this cheerful presentation, Himeno also holds an extremely pessimistic worldview as a result of having witnessed multiple partners die suddenly in her line of work. This knowledge that Devil Hunters typically die as a result of their career combined with the teachings of her master eventually lead to her developing a nicotine addiction as a coping mechanism, as well as excessive drinking. Himeno has strongly internalised another old teaching of her master: that only Devil Hunters "who have a couple of screws loose" are ultimately successful, due to the general sense of unpredictability presented by their willingness to do unusual things to take down opponents. Himeno deeply dislikes Makima, her boss, and recognizes her manipulative nature, even calling her a "bitch" at points. She also acknowledges Makima's control over others. This control is a source of frustration and resentment for her, as she sees Makima as an obstacle to others well-being and her own desires. Himeno hates the Gun Devil. Not just because it has killed millions, but because lots of people have become Hunters with the aim of killing the Gun Devil. All of them die, and a part of her blames herself. She always tries to subtly encourage people to not try kill the Gun Devil.
