Not much is known about her personality, but she was considered to her companions as she was warning fellow demon hunters to not approach her or she will unintentionally hurt them.
Ozaki was first seen encountering Tanjirou Kamado and Inosuke Hashibira in the Natagumo Mountain, where she was being forcibly controlled by Mother Spider Demon into killing her own comrades. She warned Tanjirou and Inosuke to not come near her and to call the higher ups. She was then forced to attack Tanjirou and even doing some attack moves that were breaking her arms. As Tanjirou didn't wanted to hurt her, he made Ozaki follow him and then turned and threw her on a tree entangling her web-string into the branches to prevent her from being controlled. That annoyed the Mother Spider Demon, who decided to release the now useless demon hunters by twisting and breaking their necks, which led to Ozaki's death.
