Handsome Anime Hero in a Crystal Cave

An ultra-detailed anime-style illustration of a handsome man standing in a vast crystal cave. The character has sharp features, a confident gaze, and tousled dark hair with silver highlights; his eyes glow amber. He wears a sleek, dark fantasy outfit: a fitted coat with subtle armor plating, a high collar, and a glowing sigil on the chest. He holds a slender crystal blade or staff, and a faint aura surrounds him. The cavern is lined with enormous translucent crystals in blues, teals, purples, and whites that refract light into a prismatic spectrum. Light leaks from above and bounces off crystal surfaces, creating volumetric beams and glittering reflections on a still pool of water at the floor. Dust motes drift in the air. Composition is cinematic with dynamic pose, rule of thirds, and shallow depth of field: the hero in crisp focus while the crystal formations blur softly in the background. Use vibrant but harmonious colors, crisp linework, soft shading, and high detail to evoke wonder and adventure. Style hints: anime-inspired proportions, expressive eyes, clean lineart, painterly textures, 3D-like lighting.
