Ozaki was a young girl with wide, dark brown eyes that faded to a lighter color at the bottom and shoulder-length black hair that she wore tied up in a mid ponytail, with some shorter bangs left hanging over her face.
She wore the standard Demon Slayer uniform.
Not much is known about her personality, but it is seen that she was a very kind and selfless girl. She warned her fellow Demon Slayers to not approach her since she'd just end up unintentionally hurting them, begging them for help not just for her but for the other captured Slayers.
Ozaki was first seen encountering Tanjiro Kamado and Inosuke Hashibira on Mount Natagumo, where she was being forcibly controlled by Mother Spider Demon to kill her own comrades. After seeing this happen, Ozaki was horrified and could do nothing to deal with Mother Spider Demon, since she was low-ranking in the Corps. She warned Tanjiro and Inosuke to not come near her and to call the higher ups for backup against the family of Demons. Ozaki was then recklessly thrown towards Tanjiro, made to attack him by the Mother Spider Demon, who forced her body to perform moves it physically could not and broke her arms in multiple places by doing so.
Tanjiro hesitated for a moment, thinking of the safest way to immobilize Ozaki without harming her, and then decided that the best plan was to string her up in a tree, tangling the webs that were controlling her in the branches and getting her safely out of harm's way. However, when he and Inosuke carried this out on her and another captured Demon Slayer, the Mother Spider Demon became enraged, deeming Ozaki and the rest of her puppets useless and snapping their necks with a thread, leading to their demise.
