「Stay up late」は、雨の夜の通りに立つフード姿の少年を描いた、縦型のアニメ風スマホ壁紙です。黒・白・グレーに赤を一点だけ効かせています。黒いパーカーを着た黒髪の少年が、光る街灯の下で濡れた赤い傘を持ち、下部中央に小さな白い文字が入っています。文字を自分の言葉に変えたり、傘の色を変えたりして、お揃いの壁紙を作れます。

Create a finished 9:16 dark anime lock-screen illustration. Keep the upper 15% relatively uncluttered for lock-screen clock visibility, with no clock or interface elements rendered. Center an original teenage boy in a dark hoodie, shown from the chest up and facing the viewer beneath a large vivid red umbrella. Keep his face fully inside a central circular safe area. Give him large expressive eyes with layered irises and two small white catchlights, clean clumped dark hair with a glossy highlight band, a simple nose and mouth, and subtle pale blush. Use crisp anime line art, heavier around the silhouette, and restrained grayscale cel shading with one hard shadow tone. A single overhead streetlight creates a narrow pale rim on his hood and shoulders; rain streaks cut through its cone of light. Behind him, a softly blurred rainy night street recedes into grayscale bokeh, wet pavement reflecting muted white light. The entire image stays black, white, and gray except for the umbrella, which is the only red element. At the very bottom, set the exact small text “Stay up late” in clean, compact Japanese Gothic-inspired geometric sans-serif lettering, white, with tight but readable spacing and a faint dark shadow. Keep it centered and clear of the character. No other words, symbols, red accents, or decorative typography. Moody, quiet, intimate, rain-soaked atmosphere.
