Cyberpunk Neon Oni Samurai Street Portrait

An ultra-realistic cinematic nighttime street photograph of a young man wearing a cutting-edge futuristic cyberpunk Oni samurai Halloween costume. He wears matte-black tactical techwear samurai armor with carbon-fiber shoulder plates, illuminated crimson fiber-optic wiring, a glowing demonic Japanese Oni half-mask with glowing cyan vents, and an illuminated neon energy katana sheathed at his hip. He stands confidently in an alleyway with light rain falling, one hand resting on the hilt of his katana, head slightly tilted forward with piercing eyes visible above the glowing Oni mask. A rainy Tokyo neo-noir alleyway at night with glistening wet asphalt puddles reflecting neon lights, holographic Halloween jack-o'-lantern billboards in purple and orange, and steam rising from street grates. Vibrant dual-tone neon lighting in electric cyan and vivid magenta, with rain droplets catching the rim lighting and wet reflective surfaces creating rich chromatic reflections. Medium shot from a slightly low dramatic hero angle, Shot on Canon EOS R5 with RF 50mm f/1.2L lens, cinematic shallow depth of field, rich dynamic range, --ar 3:4, 8k detail, photorealistic rain droplets, hyper-detailed carbon fiber and neon textures.
