【Nano Banana、加工された自撮りの生成もレベル高いことが判明】

普通にかわいいし、加工アプリ特有の質感とか結構ドンピシャすぎてもはや怖いです。

背景とか文字の破綻などちゃんと見たら気づきますが、ほとんどの人はもうAIか判別できないでしょう。

"description": "A realistic yet cute smartphone selfie of two young Japanese women in police cosplay, taken in a dimly lit bar (con-cafe) where karaoke is playing. The image captures a '2016 Jirai-kei' aesthetic with a focus on natural cuteness rather than heavy, scary processing. The two friends have distinct looks, posing cheek-to-cheek.",
"subject": {
"count": 2,
"demographics": "Two young Japanese con-cafe workers. They look young, cute, and distinct from each other.\n1. Left Girl: Traditional 'Jirai-kei' look with black hair.\n2. Right Girl: 'Ryousan-gata' idol style with pastel pink hair, looking sweeter and softer.",
"appearance": {
"hair": "Left: Black hair with a 'hime-cut' (blunt bangs and sidelocks). Right: Pastel pink hair tied in fluffy twin tails with ribbons.",
"apparel": "Matching light blue police cosplay shirts. The neckline is slightly open but kept cute with lace chokers. Silver accessories.",
"pose": "A classic 'con-cafe cast' selfie. They are leaning their heads together intimately. Hands are posed near their faces in 'peace signs' or 'paw poses'. The camera angle is high-angle selfie style, but the phone itself is NOT visible.",
"eyes": "Large, doll-like eyes with dark, natural-blending circle lenses. The Left Girl (black hair) wears dark charcoal gray or black circle lenses. The Right Girl (pink hair) wears natural, warm brown circle lenses that complete her cute look. The colors are muted and deep. No glasses."

},
"environment": {
"location": "Background is a dimly lit bar counter with blurred liquor bottles (bokeh). Crucially, a monitor screen is visible in the background, playing a karaoke video with blurred lyrics subtitles and typical karaoke imagery, contributing to the atmosphere.",
"lighting": "Soft, frontal lighting typical of a selfie (simulating a screen light). No harsh shadows, no weird glowing eyes. The background monitor adds a faint, colored glow."
},
"style": {
"aesthetic": "2016 Japanese selfie style (like SNOW or B612 app).",
"image_quality": "Soft, pastel-tinted, and smooth. Not 'kebai' (gaudy). It looks like a cute memory from a night out singing karaoke."
