"The one whose fangs are the sharpest wins. Thus, Killing Bites."

Uzaki Hitomi is one of the main protagonists of the Killing Bites series. She is a ratel therianthrope and a Brute in Killing Bites known as Brute Ratel who answers to Shidou Reiichi.

Hitomi is a young girl of average height with short white hair, which includes bangs covering her forehead, brown eyes, and possesses an athletically toned body. She normally wears her high school uniform, which is a white unbuttoned collar shirt with a red bow, a brown jacket, a blue skirt, white socks that goes up to her legs and sandals. As for her fighting attire, Hitomi prefers to wear a simple white crop top and exposed white panties while walking barefoot. After the timeskip, Hitomi starts wearing a different crop top with a jacket over and shorts.

Hitomi has an extremely fierce personality that makes her out to be rather unfriendly and intimidating around others. She will pick a fight against anyone with very little provocation if they annoy her, therianthrope or not. She has no shame or resistance in her state of dress when fighting but is conscious about acting more feminine despite her tomboyish attitude. Hitomi isn't exactly knowledgeable about most perverts unless they make a move. For example, after Yuuya accidentally grabbed her breast, Hitomi blushed and called him a pervert, followed by a punch to the face. However, when she was misguided by Eruza into dressing as a maid while keeping some of her therianthrope traits visible, she was oblivious to the fact that other boys were completely ogling her until much later on. She also has a fondness for sweets that makes her give off a cute, normal girl expression on her face. The most common times when Hitomi will break out of her violent behavior is whenever she encounters Shidou Reiichi (or be given an order by him through communication) where she switches into a respectful, sweeter, and cuter person that is very obedient.
