【解説】画像生成NSFW表情タグ

1.はじめに

この記事では、Pony系画像生成モデルのNSFW表情タグを実例と共に解説していきます。

NSFW画像は、竿役又はヒロインに共感する事で、エクスタシーを感じている側面があります。

そのため、キャラクターの表情は重要です。

ある程度は指定しないでもシーンに合わせてくれるのですが、物足りないケースが多いです。

そのために、明示的に表情タグを含めるのが望ましいです。

【考察】漫画的エフェクトの生成方法

1.はじめに この記事では、NSFW画像の生成時に漫画的エフェクトを導入する方法について考えていきます。 漫画的エフェクトとは、例えば次のものです。 best quality, otoko no ko, maid, yaoi anal standing sex, grabbing from behind, 2boys, arm support, screaming, penis, (testicles), erection, maid headdress, ...

以前、エフェクトについては解説しました。

・モーションブラー(motion blur)

・モーションライン(motion lines)

・速度線(speed lines)

・震えを表す線(trembling)

などが挙げられます。

エフェクト同様に重要なのですが、今までメインでは解説してこなかったので、解説していきます。

4.解説

よく使う表情タグと今回使ってみた表情タグは、次のものになります。

### ①導入

```

embarrassed

←恥ずかしがった（Danbooruタグ、e621タグ）

surprised expression

←驚きの表現（e621タグ）

seductive smile, bedroom eyes

←蠱惑的な笑顔（Danbooruタグ）、蠱惑的に見つめる（e621タグ）

naughty face

←小悪魔顔（Danbooruタグ、e621タグ）

in heat

←発情期（e621タグ）

aroused

←興奮した（Danbooruタグ、e621タグ）

```

### ②快感

```

looking pleasured

←悦んでいるように見える（e621タグ）

anal orgasm, orgasm face

←アナルオーガズム、オーガズム顔（e621タグ）

drooling, saliva

←よだれ（Danbooruタグ、e621タグ）

```

### ③極度の快感

```

torogao

←トロ顔（Danbooruタグ、e621タグ）

ahegao

←アへ顔（Danbooruタグ、e621タグ）

fucked silly

←アへ顔に近い極度の興奮（Danbooruタグ、e621タグ）

```

### ④事後

```

afterglow

←光悦（Danbooruタグ、e621タグ）

blush

←赤面（Danbooruタグ、e621タグ）

heavy breathing, panting

←激しい息遣い（Danbooruタグ）、喘ぎ（e621タグ）

sweat

←汗（Danbooruタグ、e621タグ）

heart

←ハート（Danbooruタグ、e621タグ）

```

これらの表情をより強く描写して欲しい時には、WebUIの強調表現が使えます。

https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Features#attentionemphasis

ただ、その強調表現だけではなく、類似の意味のタグを重ねて使う事で強調する事もできます。

```

ahegao, fucked silly

```

強調表現は重みを強くし過ぎると画像が破綻していきます。

しかし、タグを重ねて使うケースでは、あまり破綻は見ないです。

5.おわりに

今回は表情をメインテーマにしていますが、サブテーマとして複数のお試しをしています。

### ①SDキャラ

```

chibi only

←SDキャラ

white outline

←白い枠線

full body, full-length portrait

←全身、全身像

```

これは成功しました。

### ②体位タグ

```

kneeling oral position

reverse stand and carry position

69 position

chair position

anvil position

table lotus position

fleshlight position

mermaid position

leg glider position

```

これらの体位に関しては、e621のWikiでsex positionsとして紹介されているものになります。

不確定な要素はあるものの、ある程度は成功したとみています。

### ③挿入深度

```

balls deep

←深い挿入（竿全てが挿入済み）

deep penetration

←深い挿入

shallow penetration

←浅い挿入

```

これも成功しているようです。

### ④縦横比変更

縦横比変更も試しています。

縦横比に応じて、生成しやすい構図が変わります。

基本的には縦長の方がキャラクター画像としては向いています。

ただ、横長の方が、四つん這いや横になる体位では向いていたりもしますし、顔の見えない男(faceless male)も出しやすくなります。

https://taziku.co.jp/all/sdxl-size

### ⑤全裸状態での肥満属性分離

肥満の意味のタグを含めた上で、竿役・ヒロイン共に全裸を前提にすると、高確率で竿役だけでなくヒロイン側にも適用されます。

それを回避できているようです。

これは、版権キャラである事とSDキャラである事の両方が効いていると考えています。

従来のDanbooruタグだけではなく、e621タグも含めるようにすると、プロンプトで使用できる語彙が増えますので、ぜひあなたにもお試ししていただきたいです。

新たな性癖を開拓いただければと、考えております。
