A black-haired female character in a shoulder-exposing fighting outfit focuses intently ahead

A close-up bust shot of a black-haired female character, with her long hair tied up in a high ponytail and a few damp strands sticking to her flushed cheeks and forehead. She has a furrowed brow and sharp, focused eyes staring straight ahead, with fine sweat beading on her forehead and shoulders, giving her skin a healthy glow after exercise. She is dressed in a blue and white off-shoulder combat outfit, with a white knot at her shoulder. The background features hazy indoor light spots, and soft top lighting delicately outlines the lines of her shoulders and neck as well as the texture of the fabric, presenting an exquisite and realistic anime art style.
