"Extreme close-up portrait of Serpent Hashira Obanai Iguro emerging from complete darkness. Only half of his face is illuminated by a cold, sickly purple and pale yellow light while the opposite side disappears into absolute black shadows. His striking heterochromia eyes become the main focal point, with one glowing turquoise-blue eye and one yellow eye, radiating deep-seated anger, strict intensity, and unwavering determination. The white bandages covering his lower face are intricately detailed with fine fabric textures and subtle dirt. His straight, jet-black hair is rendered with razor-sharp crystalline strands, catching the divine light with extraordinary detail. His face and bandages carry subtle battle scars, dust, scratches, and slight blood marks. Resting on his shoulders, his white snake Kaburamaru looks forward with glowing red eyes. A restrained purple serpent-like aura gently wraps around his silhouette like flowing mist. Tiny glowing toxic-purple particles drift slowly through the darkness while subtle spatial distortion bends the surrounding air.
