被四名反派包围的天使

Create a dramatic vertical anime fantasy key visual featuring {argument name="main character" default="an innocent white-haired angel girl"} in the foreground and exactly four dark enemy characters behind her. Canvas: tall smartphone wallpaper composition, 9:16 ratio, highly polished Japanese light-novel/anime illustration, cinematic lighting, sharp detailed linework, glowing particle effects, no text. Foreground subject: the angel girl is centered from waist up, facing forward with a calm fragile presence; very long flowing white hair, pale skin, small white flower hair ornament near one ear, loose white ruffled dress with short puff sleeves and a pale lavender waist ribbon, large pure white feathered wings spread to both sides, soft bright rim light and ethereal glow. Background enemies: arrange exactly four villainous figures in a layered semicircle above and behind her, all looking serious and hostile, mostly dressed in black, crimson, white, and gold gothic-fantasy clothing. Enemy 1, upper left: tall dark-haired man in a black high-collar military/gothic coat with chains and red accents, gloved hand near his mouth, ominous aristocratic pose. Enemy 2, upper right: pale lavender-haired gothic woman in a dark frilled headdress and black-and-purple dress with red rose accents, one hand lifted near her face, spectral and elegant. Enemy 3, middle left: silver-haired young man in a white ornate coat with fur-trimmed shoulder cape and gold chains, holding a glowing red magical orb in one hand. Enemy 4, middle right: long blond-haired noble man in a white-and-black outfit with gold epaulets, red cloak or sash, black glove raised as if casting magic. Environment: a swirling crimson demonic background filled with red nebula smoke, black shadows, sparks, blood-red magical energy rings, ember particles, and glowing red orbs, creating a strong color contrast between the angel’s white purity and the enemies’ red-black menace. Mood: beautiful but ominous, as if an angel is surrounded by complex antagonists rather than simple demons. Use {argument name="background color palette" default="deep crimson, black, and glowing red"} with intense backlighting, dramatic depth, and no visible watermark or captions.
