【Illustrious-XL系】NSFW男の娘画像生成

# 1.はじめに

この記事では、Illustrious-XL系の画像生成AIでのNSFW男の娘画像生成方法を解説していきます。

Illustrious-XLは、SDXL派生モデルの一つで、次の特徴があると聞いています。

①キャラクター名＋登場作品名の指定での版権キャラ再現に強い。

②アーティスト名指定での画風再現に強い。

③ただし、デフォルトの画風の安定性は低い。

バージョンが0.1であり、③の欠点があるのは仕方ないのですが、その欠点を補って余りある①②の長所があるそうです。

■本家モデル

既に派生モデルがいくつも作られているのですが、それらの派生モデルでは③の欠点もある程度解消されているらしいです。

そのため、この記事では本家のイメージに近そうな派生モデルで、生成を試していきます。

ただし、デフォルトの画風を把握したいので、アーティスト名のプロンプト指定はしていません。しかし、ある程度の画風の一貫性は欲しいので、2020年を意味する「2020」のみ設定しておきます。

# 4.解説

驚いた事に、版権キャラの安定性が非常に高いです。

旧衣装のブリジットちゃんが、LoRA抜きで固定できています。

また、sound effects（効果音）で、読める日本語が生成される事もあるようです。

加えて、①と②でお分かりになる通り、陰部の描写も安定しているようです。（非勃起{flaccid}画像の生成も、成功率はそこそこあります）

プロンプトの組み方としては、Danbooruタグでのものとなります。

そのため、基本的なプロンプトの組み方はAnimagine XLを踏襲すれば良いと思われます。

ただし、Animagine XLよりもNSFWなタグが機能しやすいようなので、Animagine XLで諦めていたタグも試して良いと思われます。

なお、品質タグは

masterpiece > best quality > good quality > average quality > bad quality > worst quality

のようです。

また、版権キャラは「キャラクター名＋登場作品名」のみでも十分に再現性があります。

そのため、版権キャラ同士の絡みもしやすいようです。

# 5.おわりに

Illustrious-XL系は二次創作特化モデルと言っても良く、キャラ愛が強い方々に好まれそうです。

また、e621タグが使用できるようにファインチューニングされたものもあるようなので、pony系から移行される方はそれを試してみても良いかもしれません。

ただ、男の娘描写力は「Animagine系 <<< Illustrious-XL系 < Pony系」の印象を持っています。

そのため、移行というよりも使い分けが良い塩梅なのではないかと思います。

あなたのキャラ愛あふれる作品を、お待ちしております。
