Aogiri belongs to the Hog Squad in the all-female ninja community, the Akane Class. She wears a distinctive eyepatch over her right eye and sports black hair in a low ponytail. Her attire is a white and black hakama, featuring an exposed right torso and a single long sleeve on her right arm; she is typically shown barefoot.

Standing 160 cm tall, Aogiri is a master of iaido, wielding her katana with exceptional skill. Her sword swings possess blinding speed, moving faster than the eye can easily follow, enabling her to effortlessly slice through objects like boars or trees. The katana is her primary weapon, reflecting her deep affinity for swords and dedication to her combat style.

Personality-wise, Aogiri dislikes being mocked. She once struggled to display natural facial expressions, particularly smiling, but through guidance from Mokuren, she has learned to show a slightly unusual, yet improved smile.
