Create a full-body portrait of a dark ninja character inspired by Sonic from One Punch Man, fully in the style of Magic: The Gathering. Vertical four-fifths aspect ratio. The character is slender, muscular, and agile, standing in a ready stance, slightly leaning forward. Long black hair tied in a high ponytail, flowing naturally. Wears traditional Japanese ninja garments: dark, loose, flowing fabrics, minimal belts or straps, no modern or technical details. Holds short ninja swords in both hands, with subtle glowing aura of energy (Ki) around the blades. Background is nighttime or twilight, mysterious and moody, with dramatic, painterly lighting highlighting muscles, facial features, and clothing folds. Realistic proportions, high detail, textures visible on fabric and hair, epic fantasy illustration with cinematic composition, chiaroscuro lighting, dark palette with cool color accents, fully in Magic: The Gathering illustration style. No anime or cartoon style.
