ruined city battle stance long haired woman short haired man

In the midst of a ruined city, a man and a woman stand back-to-back, poised for battle. The woman is tall with hair that is a mix of black and brown, her expression resolute and determined for combat. Her long hair is tied back. She wears a torn blue jacket as her top and heavily ripped black skinny jeans as her bottom. Her shoes are dirty sneakers. The man has a clean appearance with short hair and looks to be about high school age. He appears to be of East Asian descent and seems to be in good physical shape, likely from regular exercise. His outfit is a full-body, skin-tight suit that clings to him, its surface rough like a pinecone, and it is a reflective silver color that covers him down to his feet. In one hand, he holds a sharply designed long sword, and a blue aura emanates from his body.
