Design an anime-style character named Hikaru, the 'Shadow Ninja

Design an anime-style character named Hikaru, the 'Shadow Ninja.' Hikaru should have a stealthy, enigmatic expression, with sharp, focused eyes and a nimble, agile pose. Outfit him in dark, sleek ninja attire with shadowy patterns and hidden weapons. The background should be a moonlit cityscape with dark alleys and subtle shadow effects. Capture Hikaru’s stealth and precision.
