Japanese Underground Idol Live Stage Photo AI Image Prompt

Create a realistic vertical concert photograph of a smiling {argument name="performer description" default="young Japanese underground idol singer"} performing on a small dark live-house stage. She is framed from mid-thigh upward, slightly angled in a dynamic pose, making direct eye contact with the camera while pointing toward the viewer with her left hand and holding one black handheld microphone near her mouth with her right hand. She has long dark brown wavy hair with straight bangs and exactly 2 small silver hair clips on one side, bright cheerful expression, natural idol makeup, and glossy stage-lit skin. Her outfit is an all-black tactical idol costume with exactly 7 visible key pieces: 1 sleeveless cropped vest with metal snaps, 1 black harness with straps and metal rings, 1 black belt with buckle at the waist, 1 pair of high-waisted black shorts, 1 fingerless black glove on the microphone hand, 1 thigh strap, and 1 rectangular pouch holster on the thigh.

Set the mood to {argument name="stage mood" default="intimate basement idol concert"}; keep the background mostly black and uncluttered, no text, no watermark, no extra performers.
