Game Asset - Social Game Special Move Production Prompt for Nano Banana Pro

@とすくん·

A highly detailed, multi-section prompt designed to generate a screen capture of a social game's special move sequence (cut-in, move name, damage display). It strictly requires maintaining the character's original art style from a reference image while inferring dramatic effects, UI, and a random, chuunibyou-style Japanese move name and damage value.

Prompt
Quality: Ultra High Quality / 4K equivalent / High definition / High contrast Format: Special move activation scene UI for the latest smartphone games Usage: Official game-level screenshots shared on social media ──────────────────── [Most Important: Complete Fixation of Character Art Style] ・Do not change the facial features, eye shape, pupil texture, contour, hairstyle, coloring, color usage, or atmosphere of the character in the input illustration at all. ・Prohibit changing the character into a different person, a different artist's style, or changing the art style. ・Treat the character as an “extension of the original illustration.” ・Prohibit redrawing, redesigning, or reinterpretation. [Scope of Inference Allowed] ・Inference is limited only to the following: UI / Text / Effects / Damage numerical value / Direction ・The character's appearance, perceived age, and impression are completely fixed. ──────────────────── [Composition/Camera] ・Bust-up to waist-up composition. ・The character occupies 60-70% of the screen. ・The face, especially the “eyes,” should be positioned toward the top or sides of the screen. ・Do not place any text, UI, or effects around the eyes. ・Full-body composition is prohibited. ──────────────────── [Special Move Name (Main Subject, Maximum Display)] ・Fixed display in the center of the screen. ・Extra-thick, extra-large Japanese brush script. ・The maximum size currently possible. ・Part of the text extends off-screen. ・Absolutely do not overlap the character's face, especially the eyes. [Gold Border of Move Name (Fine Adjustment, Important)] ・Adjust the gold border to be “slightly thin.” ・Tighten the border to increase text density. ・Keep the gold glow subdued, prioritizing contrast with black solid color. ・Prioritize logo feel and weight, reducing flashiness by one level. [Rule for Generating Special Move Name] ・Generate a completely original Japanese move name each time, based on the world view, attribute, and atmosphere of the input illustration. ・Chuunibyou-style and profound. ・Include elements such as mythology, judgment, azure ice, crimson lotus, demise, machine, and divinity. ・Prohibit existing work names, proper nouns, examples, or samples. ・Do not display “Example,” “Sample,” or “placeholder” at all. ──────────────────── [Move Power (Variable, Optimized)] ・The power of the special move displays a different numerical value each time. ・Damage numerical values are randomly generated within the following range: 12,000,000 ~ 98,000,000 ・Fixed maximum value is prohibited. ・Prohibit repeating digits, maxed-out values, or exact matches. ・Prioritize natural, strong-looking, non-uniform numerical values. [Damage Numerical Font (Weight Enhancement)] ・The font is thick, angular, and has a low center of gravity. ・Slightly wider horizontally, not overly compressed vertically. ・Metallic/rock-like massiveness. ・Subdued glow, using shadow and three-dimensionality to convey weight. ・Gives the impression that the “numbers themselves are heavy.” [Power Display Composition] ・CRITICAL!! must be displayed. ・Damage numerical value has the maximum presence in the center of the screen. ・Visual flow: CRITICAL → Numerical Value → Move Name. ──────────────────── [OVERKILL Display Rule (Most Important)] ・Do not display OVERKILL text at all. ・Do not use it anywhere in the text, UI, or effects. ──────────────────── [Character Information UI] ・Rarity (UR / LR) ・Lv.MAX ・Small and consolidated at the top of the screen. ・Does not assert itself more than the character. [HP/Gauge] ・HP bar is thinly placed at the bottom. ・Convey that HP is 0 or less only through the gauge representation. ・Prohibit emphasis via text. [Other UI] ・AUTO / SPEED / MENU are placed minimally at the edge of the screen. ・Semi-transparent design, not information-overloaded. ──────────────────── [Direction Policy] ・Only the center (Move Name + Damage) moves intensely. ・The character's face, eyes, and expression remain calm. ・“Art style is static, text and numbers are heavy, effects are minimal but strong.” [Color Design] ・Black × Gold × Attribute Color ・Calm tones around the face. ・Maximum contrast in the center. ──────────────────── [Strict Compliance Items] ・Absolutely do not change the character's art style. ・Do not overlap text or UI on the eyes. ・Move name is centered and maximum size. ・Do not display OVERKILL. ・Do not fix the damage numerical value. ・Do not display explanatory text, examples, or supplementary text.

Style Notes

Hero Portrait
A single dominant subject shot like a key visual — tight framing, strong eye contact or pose, background simplified so the character carries the image.
Illustration
Hand-drawn or digital-painting aesthetics — visible strokes, stylized shapes and colors, deliberately not photoreal.
Logo / Icon
Symbol-first design — simple geometry that survives being scaled down, flat color, strong silhouette. Expect to vectorize the output before real use.
Marketing Campaign
Ad-ready imagery: clear product or message hierarchy, space reserved for copy and logos, and a polished commercial finish.
Minimalist
Few elements, generous negative space, restrained palette — the model is told to leave things out, which makes composition errors much less likely.
Portrait Orientation
Vertical aspect ratio (e.g. 3:4, 9:16) — the native format for phone screens, Stories, and app store screenshots.
Product Mockup
The design presented in context — packaging on a shelf, app on a phone screen, tee on a model — to preview how it looks in the real world.
Product Shot
E-commerce style product photography: the item isolated on a clean or styled surface, even studio light, true-to-material color.
