Asuka is a young woman with waist length, brown hair in a hime cut, blue eyes and a large bust. Asuka has 4 artificial limbs she can take off, near the middle of both upper legs and upper arms. Without them, she is a quadruple amputee, leaving only small stumps around the area of the upper arm and thigh. Asuka wears a pink battle suit when on duty, which keeps her back free. She wore a variation of this suit even when she was younger.

When the Taimanin Task Force requested her help in the search for the Death Wraith and Toyo, Asuka let them to a Task Force G base and a fight against some Oni and "revived" Momochi Toyo. Almost dying, she is at some point saved by Fuuma Kotaro, when her Prosthesis broke down.

Asuka assisted the Task Force later in their combined attack with the Death Wraith, against a Nomad base. She was also able to wound Edwin Black badly, with the help of Igawa Asagi and the rest of the Task Force.

"You heard it everyone, we have a mission and we must complete it at all cost, Black is wounded. let's seize the opportunity."

Asuka and her team moved out, she hoped her mother Asagi will finally see her as she is, a Taimanin Ninja, like her.
