## 実投入するプロンプト本文

```text
The same Japanese man from the reference image, early 30s — as himself, the real person, no costume, no transformation. Preserve his face, curly hair texture, skin tone, and facial features exactly as in the reference. He is wearing his natural white collared shirt with a navy knitted vest and subtle blue striped tie — exactly the outfit in the reference. Standing in a modern Japanese startup office at golden hour, warm window light streaming from camera-left casting a soft glow on his skin.

Behind him in soft bokeh: a folded canvas director chair, a boom microphone leaning against a wall, a half-visible news-anchor desk corner, a samurai kabuto helmet displayed on a shelf, a black baseball cap hanging on a coat hook, a BBQ apron folded on a sofa, a fake plastic tombstone leaning on a bookshelf — subtle intentional props from his previous transformations all scattered casually in the background. These should read as behind-the-scenes Easter eggs, not in-your-face, visible but not central.

An honest warm human expression, a knowing confident smile directly at camera with slight head tilt, as if silently saying I was all of them. Light crinkles at the corner of his eyes.

Vertical 9:16 portrait framing. Medium close-up, chest and head. Photorealistic ARRI Alexa cinematic look, shallow depth of field focused on his face (background props softly out of focus), natural subsurface skin scattering, visible skin pores, subtle 35mm film grain. Preserve the reference person's identity completely — this must clearly be the same person as the reference photo, unchanged. No readable text, no logos, no watermarks, no CGI-look, no cartoon.
