Tsubaki.2 プロンプトガイダンス- プロンプト作成の極意

はじめに

PixAIが開発したプロプント自動変換は、エージェント機能を備えたインテリジェントなプロンプトアシスタントです。プロプント自動変換を有効にすると、入力した短いプロンプトをシステムが自動的に拡張・補完し、使い始めのハードルを下げると同時に、生成の安定性と画面表現の効率を向上させます。

本ガイドは、ユーザーがプロンプトの書き方をより深く理解し、上級ユーザーにはより体系的な創作方法を提供することを目的としています。Tsubaki.2が「元のプロンプト」にどのように反応するかを正確に示すため、本ガイドの後続の例と説明はすべてプロプント自動変換をオフにした状態で行っています（特に注記がない限り）。

プロンプト公式

プロンプトは画像に含まれる内容を記述するために使用され、画面のテーマと効果を制御する重要な要素です。プロンプトが完全で正確、かつ詳細であるほど、生成結果は通常より高品質になり、期待するイメージに近づきます。すぐに使い始められるよう、異なる使用目的に応じた3つの典型的な公式をまとめました。

1) 基本自然言語公式

初めてAI画像生成を試すユーザーや、AI画像をインスピレーションの源として活用するユーザーに適しています。シンプルで自由なプロンプトは、より想像力豊かな画像を生成することがよくあります。

プロンプト = [主体] + [動作] + [場面]

主体：画面の主な表現対象。人物、動物、植物、物品、または架空の想像上の存在が可能です。
動作：主体の動作または運動状態。風、雨、煙などの非主体の動き表現も含められます。静止、小さな動き、大きな動き、局所的な動き、全体的なダイナミクスなどがあります。
場面：主体がいる環境。背景と前景を含みます。現実の空間でも架空のシーンでも構いません。
英語プロンプト：プロプント自動変換を利用していない場合、英語プロンプトの入力が必要ですので、ご注意ください。 ### 2) 高度な自然言語公式

AI画像生成の経験がすでにあるユーザーに適しています。基本公式に加えてより詳細な記述を追加することで、画面の質感、生き生きとした表現、ストーリー性を大幅に向上させることができます。

プロンプト = キャラクター呼び出し + 主体外観記述 + 場面記述 + 姿勢・動作記述 + 撮影美学制御 + Tsubaki.2スタイルプリセット

キャラクター呼び出し：下記のプロンプト辞典を参照。
主体外観記述：主体の外観と特徴の詳細を補足。形容詞や短いフレーズを使用できます。人物の主要な外見記述（表情、服装、体型、髪型など）と人物の細部補足（目、メイク、アクセサリー、タトゥーなど）を含みます。下記のプロンプト辞典を参照。
場面記述：環境の雰囲気、構成、詳細の補足。形容詞や短いフレーズを使用できます。
姿勢・動作記述：主体の体の姿勢を記述。動作の範囲、速度、効果を含みます。
撮影美学制御：光源、光環境、景別（ショットタイプ）、アングル、レンズ、カメラワークなど。一般的なカメラ用語は下記のプロンプト辞典を参照。
Tsubaki.2スタイルプリセット：Tsubaki.2には39種類のスタイルプリセットが内蔵されており、直接選択して全体のスタイルを制御できます。下記のプロンプト辞典を参照。

3) Tag公式

Tsubaki.2はTag入力をサポートしています。ただし、Tagは本質的に「オブジェクト間のインタラクション関係」の記述が苦手なため、Tag使用時はプロプント自動変換を有効にすることを推奨します。プロプント自動変換をオフにする必要がある場合、生成結果にはある程度のランダム性と不安定性が生じる可能性があります。

主体外観記述

人物の主要外見記述（表情、服装、体型、髪型など）

A best-quality, high-resolution anime illustration of a shy girl framing her from mid-thigh to the top of the head for a gentle, intimate perspective. She faces the viewer with a soft, hesitant expression, heavy pink blush across her cheeks and nose, and large pinkish-red eyes with glossy catchlights.**Her lips are slightly parted, conveying bashfulness.**

A full-body shot of a mecha-musume. She is wearing a cute, frilly white maid mini-skirt on her right side, but the left side of the skirt is torn away, revealing a massive, fully mechanical, tank-tread-like robotic left leg. Her right leg is a normal human leg wearing a white stocking.

A close-up of a girl in the rain.She is wearing a highly translucent, clear plastic raincoat. Underneath the raincoat, she is visibly wearing a classic red-and-black lumberjack flannel shirt. The red plaid pattern must be clearly visible through the transparent plastic material of the raincoat, complete with water droplets on the outside.

人物の細部補足（目、メイク、小物、タトゥーなど）

A delicate, high-detail anime close-up portrait in a soft pastel palette, framed tightly from the top of the head to the upper chest. The composition is slightly off-center, emphasizing one large, glossy eye (cool gray-blue) with layered iris rings and bright catchlights.

She has pale icy-blue hair in a bob with airy, semi-transparent strands and wispy bangs falling over the forehead; fine flyaway hairs arc across the face for an ethereal feel. A small white hair accessory sits near the top, and a geometric dangling earring (dark angular frame with an iridescent inner shine) is visible on the near ear.

The scene is decorated with white blossoms floating and overlapping the frame—some in sharp focus near the face, others softly blurred—creating a dreamy, layered depth. Tiny water droplets / dewdrops cling to hair strands and float in the air, catching light like glass beads. Lighting is bright, diffused, and high-key, with soft overexposed highlights and gentle rim light along hair edges; shadows are minimal and silky, maintaining a clean, airy look. The background is an abstract wash of pale aqua and white, with subtle bokeh-like softness, emphasizing the fresh, springlike, translucent atmosphere

This is a low-angle, eye-level close-up, front-view composition with direct viewer eye contact, capturing the subject from mid-chest upward as she lies on her back on a rumpled bed. The framing emphasizes her exposed collarbone, wet shirt clinging to her torso, and the subtle sheen of sweat on her skin. Her medium-length black hair is damp and partially obscures her forehead, with visible eyebrows just beneath the wet strands. Her black eyes are large and glossy, reflecting ambient light, with parted lips and a closed-mouth expression conveying quiet exhaustion. She is barefoot, one arm bent beneath her, the other still tucking in the hem of her open black jacket over a white sweater, now soaked through and translucent. Her long sleeves are wet and adhered to her arms. The bedsheet beneath her is dark and wrinkled, with faint water droplets glistening on its surface. A single droplet hangs from her chin, about to fall. The entire scene is rendered in a glossy, “glass-like” anime style: lively, bouncing linework, oversized expressive eyes, and strong highlight-heavy rendering with sparkly water reflections. Colors are bright and clean — stark white sweater, deep black jacket, and saturated wet textures — all under cool, even indoor lighting that enhances the wet sheen on skin, hair, and fabric.

Soft anime-style eye makeup with a warm, luminous palette. The eyelids are framed by muted red to coral-red eyeliner and eyeshadow, applied primarily along the upper lash line and inner corners, creating a gentle halo effect rather than a sharp wing. The color softly diffuses outward, blending into the skin with minimal hard edges.

The irises are golden amber with peach undertones, rendered with layered gradients and multiple soft highlights that give a glossy, glass-like appearance. Highlights are rounded and irregular, suggesting reflected light rather than stylized sparkles. The sclera remains clean and bright, enhancing contrast.

Lower lashes are subtle and sparse, drawn with thin, sketch-like strokes; no heavy lower eyeliner. Overall impression is natural yet emotionally expressive, warm, slightly melancholic, and softly illuminated—more painterly than graphic, avoiding harsh lines or high saturation.

This is a digital illustration rendered in a modern anime style with clean lines, soft gradient shading, vivid colors, and glossy highlights. The image captures its subject in a low-angle, front-view medium shot. A young adult female character is centrally framed and isolated against a simple white background. Her raised arms and flowing hair create a dynamic, asymmetrical composition that fills the frame. She has very long, straight, light ash-blonde hair that appears wet, with asymmetrical bangs covering her left eye. A glowing light blue halo floats above her head, and a blue butterfly hair ornament is attached to the right side of her hair. Her visible right eye is a vibrant cyan blue. She has a playful smile, revealing her upper teeth, and a faint blush on her cheeks. A small mole is visible on her left breast. She wears a sleeveless, form-fitting white dress with a lace-trimmed, low-cut neckline and black corset-style lacing on the bodice. Her attire includes a thin black choker, long white gloves, and a black ornate tattoo on her left bicep. A translucent blue ribbon wraps her waist, adorned with a large blue rose. Large, translucent blue butterfly wings emerge from her back. Her pose is dynamic; she stands with both arms raised behind her head, biting a blue ribbon from her hair ornament. Several smaller, glowing blue butterflies and white sparkles surround her.

場面記述

A purely minimalist anime illustration. A single, extremely small silhouette of an anime girl holding a black umbrella standing in the very bottom center of the image. The entire rest of the image (95% of the canvas) is a vast, empty expanse of pure, flat white snow merging seamlessly into a pale, blank overcast sky. Absolutely no other objects, no background details.

A wide-shot night scene on an urban rooftop captures two faceless girls in school uniforms standing side by side, silhouetted against a vast blue-themed sky filled with ethereal flying whales and fish. The rooftop features a low ledge and scattered air conditioning units, with the girls positioned centrally, their backs to the viewer, gazing outward. One girl has long hair flowing in the wind, the other shorter hair, both wearing pleated skirts and blouses with neckties, rendered in deep monochrome blues. Majestic flying whales with outstretched fins and schools of flying fish glide gracefully across the expansive sky, some passing close to the rooftop. The city skyline of tall buildings fades into the distance, illuminated by subtle backlighting from the moon. Soft, diffused light creates glowing rims around the silhouettes and creatures, enhancing the serene, dreamlike atmosphere. The color palette is exclusively cool blues and blacks, with intricate details in the whales' textured skin, fish scales, hair strands, fabric folds, and rooftop gravel. Gentle motion blur on the flying creatures suggests graceful movement, evoking a sense of quiet wonder and nocturnal tranquility.

Full-body shot from behind at beach sunset, 1girl with long brown hair in side ponytail secured by large bow, sitting on sand facing away toward ocean, school uniform with puffy long sleeves, three-quarter sleeves, vertical striped skirt, and striped blouse, accompanied by 1other with pink short hair. She sits with knees drawn up, arms wrapped around legs, head turned slightly right, serene expression implied. Detailed sand texture with footprints, gentle waves lapping shore, distant birds flying, scattered seashells, cloudy orange sky, warm golden sunlight casting long shadows and rim lighting on hair and fabric folds.

A clean, minimal anime illustration of a young woman recording music in a simple studio setup, framed in a medium-full shot against a plain light-gray background. She sits cross-legged on the floor while playing an acoustic guitar, her left hand forming chords on the fretboard and her right hand strumming near the sound hole. Her expression is lively and relaxed, mouth slightly open as if singing. She has short, sandy-blonde bobbed hair with soft layers and side-swept bangs, warm brown eyes, and a subtle blush. She wears a thin black choker and casual layered clothing: an oversized dark jacket draped off her shoulders over a loose, light-colored long-sleeve top, paired with dark shorts. On her feet are chunky dark sneakers with visible laces. Above and slightly to her left is a suspended studio microphone on a boom arm, with a round pop filter positioned in front of it, angled toward her mouth. The linework is crisp and understated with soft, flat shading and gentle gradients, giving a calm, slice-of-life mood. Lighting is soft and diffuse, with minimal shadows—just enough to define the guitar’s shape and her clothing folds—keeping the scene airy and uncluttered.
