ダークゴシックなネオンシティのファンタジーマフィアボス

A fantasy mafia boss in a dark gothic city, wearing a tailored black suit with subtle arcane symbols, silver rings, and a signet ring glowing faintly with magic. Cold sharp eyes, calm but dangerous aura. Shadowy skyscrapers mixed with medieval towers in the background, neon lights cutting through mist. Black ravens flying overhead, moonlight reflecting on wet streets. Cinematic lighting, ultra-detailed, dark fantasy realism, dramatic contrast, 4K, high fashion mafia style, mystical underworld atmosphere, powerful, intimidating, elegant violence without action.
