Craft a vivid, hyper-detailed image of a futuristic heroine standing confidently with a glowing red lightsaber. Her sleek attire and robotic hand are depicted in intricate detail, with the soft light from the moon creating a serene yet intense mood. In the backdrop, glowing red Japanese characters blend into the darkness, suggesting a distant, neon-lit city. Focus on strong contrast between the red light of the lightsaber and the cool moonlight, using HDR and sharpening effects to highlight her fierce expression. Add color grading to enhance the mood and lens flare for the lightsaber’s glow.
