Tactical Underground Idol Concert

Create a photorealistic vertical concert photo of {argument name="performer type" default="a cheerful Japanese underground idol singer"} performing on a small live-house stage. She is a woman in her early 20s with long dark brown hair, straight bangs, soft wavy ends, and a small silver hair clip, smiling brightly while looking directly at the camera. She holds a black handheld microphone close to her mouth with one hand and extends her other arm toward the viewer in a playful finger-gun pose, creating strong foreground perspective. Dress her in an all-black tactical idol costume: sleeveless cropped vest with straps, buckles, zipper details, fingerless glove or wrist cuff, high-waisted fitted shorts, belt harness, thigh strap, and a black holster pouch on one thigh. The mood should be {argument name="style fusion" default="cute idol energy mixed with tactical military fashion"}. Use dramatic dark stage lighting with a bright circular LED spotlight glowing behind her on the left, cool blue haze, black ceiling rigging and stage equipment in the background, shallow depth of field, realistic skin texture, crisp focus on her face and microphone, and a candid live-performance photography look. Vertical 3:4 composition, waist-to-thigh framing, dynamic pose, no text, no watermark, no extra performers.
