vertical anime ACTion poster featuring [ADULT MIKASA ACKERMAN]] from [Attack on Titan] as the mAIn subject. The character leans toward the camera from a low-angle close-up perspective, holding a sharp ODM gear blade toward the lens. The blade, hilt, and fingers dominate the lower foreground with extreme foreshortening, partially blurred by shallow depth of field.

Preserve the character's iconic hairstyle, facial features, fierce green eye design, Survey Corps outfit silhouette, muted military color palette, ODM gear accessories, and intense rebellious Personality aura. Dark cinematic anime style, sharp ink outlines, dramatic shadows, high-contrast lighting, ruined city battlefield background, strong diagonal composition, vertical social-media crop, red handwritten graffiti-style anime title lettering across the lower foreground, dynamic fan-edit poster energy.
