Deeply analyze the content of the input text provided at the end, and generate a **high-click-through-rate horror-themed thumbnail image** that simultaneously incites fear and curiosity in viewers. In doing so, introduce the character from the attached reference image to match the **dark and unsettling world view**, positioning them as a **"Witness who has touched the forbidden."** Maintain character consistency while naturally blending them in with expressions distorted by fear or tense poses. ▼ Instructions for the Generation Process (Thinking Process) Utilize Nano Banana Pro's reasoning ability and execute the following thought process before drawing: 1. **[Step 1: Concept Extraction]**: Extract the **Uncanny Valley** created by the contrast between the "silly name Nano Banana" and the "logical, super-performance AI" from the input text. Find elements where cuteness becomes grotesque. 2. **[Step 2: Visual Translation]**: To visualize the "Thinking Mode," adopt a depiction where the space around the character is encroached upon by digital noise or glowing neural circuits. Grotesquely reinterpret the "banana" motif as decay or mechanical fusion. 3. **[Step 3: Screen Composition]**: Design a "Contrasting Composition" to enhance visibility as a YouTube thumbnail, placing the character (fearful face) on the right, the threat (symbol of distorted AI) on the left, and large text at the bottom center. ▼ Design and Style Specifications * **Composition/Layout**: Wide-angle lens (24mm), low angle view to emphasize the character's helplessness and the AI's immensity. The background is dark, with sharp spotlights hitting the subject. * **Taste**: Photorealistic Cyber-Horror. Dark, humid texture and neon contrast, similar to the movies 'Alien' or 'Blade Runner.' * **Text**: Place **"The True Identity of Nano Banana"** in a bold Mincho or grunge font in the center or top of the image. Make the text glow red (Glow effect). * **Character**: Draw the reference character in the style of a "grungy hooded explorer," specifying an expression of screaming or freezing while looking at "something" in the background. ``` ## About A detailed system prompt for Nano Banana Pro to generate high-click-through-rate horror-themed YouTube thumbnails.
