Itadori, a lowerclassman kunoichi in the Akane Class, serves on Team Tiger alongside Fuki and Ume. Her appearance features sharp grey eyes, short spiky black hair, and a prominent X-shaped scar across her forehead—a mark from hitting her head on a rock while rescuing Ume after a tree fall. Itadori openly states she likes this scar. Her attire combines a traditional sarashi chest binding, an apron-skirt over fluffy black shorts, black fingerless opera gloves, and leg bandages, typically leaving her feet bare.

Energetic, confident, and boldly outspoken, she channels her mischievous streak into pranks while maintaining a friendly core. Though generally even-tempered, she occasionally lashes out when others' habits irritate her. Her selflessness shines in her readiness to risk her life for teammates like Ume. She dislikes studying and openly expresses fondness for both Ume and Fuki.

Specializing in physical combat, Itadori leverages Swift Feet Jutsu for explosive speed and agility. Her notable strength allows feats like staggering the upperclassman Hinagiku with a single punch. Within Team Tiger, she anchors direct confrontations with high mobility.

Her bond with Ume solidified during the scar-inducing rescue. Team Tiger operates under the Akane Class's strict rule forbidding contact with men. Itadori demonstrates fierce loyalty within the team, particularly toward Ume.
