Shinazugawa Sanemi is rendered in a dynamic battle-ready stance that captures his fierce, unyielding personality. The figure features his signature white, spiky hair and a prominent facial scar across the left cheek, with a stern, piercing gaze. He wears the Demon Slayer Corps uniform with the wind-haori motif rendered in dark tones, meticulous folds, and worn textures that suggest years of combat. The Nichirin blade rests at his side, with a polished edge and subtle reflections on the guard. Fine shading highlights muscle definition, veins, and weathering on the clothing, while the base includes wind-swept effects to convey motion and the harsh battlefield atmosphere.

Shinazugawa Sanemi is one of the Wind Hashira, a veteran tainted by hardship who fights demons to protect humanity and to atone for his painful past. His youth was spent in a harsh regime where loss and suspicion hardened him, shaping a stern exterior and blunt humor that masks a deeply protective heart. He bears a complicated relationship with his younger brother Genya and a heavy burden of guilt for the deaths he could not prevent. As a senior leader, he pushes others to endure, train, and confront danger, embodying the cost of duty, resolve, and sacrifice.
