【解説】男の娘概念LoRA（プロンプト例あり）：(Concept) - Trap/Femboy/Otoko No Ko - 18 Concepts In One

※本記事での画像生成AIは、Stable Diffusion 1.5系列です。

# 1.概要

この記事は、NSFWな男の娘画像を簡単にAI生成できるようになることを目的としています。

そのために、男の娘概念LoRAモデル「(Concept) - Trap/Femboy/Otoko No Ko - 18 Concepts In One」の使い方を解説していきます。

以前の記事で簡単に紹介しましたが、より具体的な使い方をプロンプト例を示しながら解説していきます。

このLoRAモデルは、18の概念を表すタグが用意されており、それをプロンプトで指定することで、簡単に男の娘のNSFW画像が生成できるようになっています。

例えば、「OTOSUS」（男の娘駅弁）とかです。

ヘッダー画像は、このタグを使用して生成しています。

また、このLoRAモデルを使用することで、男の娘画像生成が難しいStableDiffusion派生モデルでも、それが簡単になります。

ぜひ活用されるのがよろしいかと思います。

# 2.前提条件

以降の生成例では、次のモデルを使用しています。

また、本題のLoRAモデルとして、こちらを使用しています。

# 4.解説

プロンプトが「品質タグ＋キャラ属性＋シチュ（専用タグがメイン）＋背景」のシンプルな構成で、強調表現も必要最低限なものにできています。

そして、そのプロンプトでNSFWな男の娘画像を成功率高く生成できています。

加えて、LoRAモデルあるあるな画風の変化も抑えられています。

総評として、これはかなり強力なLoRAモデルです。

現在の画像生成AIでは、男の娘キャラを生成するのには熟練を要します。

しかし、このLoRAモデルを使えば、その熟練を省略して生成できます。

LoRAモデルの製作者に感謝しながら、使わせてもらいましょう。

# 5.終わりに

ここから更なるハッテンをするためには、LoRAモデルの適用の強弱をコントロールしたり、組合せを研究したりすることが望ましいです。

前者に関しては、以前の記事で紹介しました。

後者に関しては、pixivでいくつか成果を示しています。

例えば、次のものです。

あなたの研究成果にも期待しております。
