通常、多人数を生成する場合、”2 girls”といった人数＋girls(またはboys)を指定します。裏技を使うと、Promptで通常の人数指定以上のキャラクターを生成できます。ただし、この裏技、成功するかはモデルによります。
(masterpiece,best quality), Depth of field, (bokeh), 6girls, elf, highschool uniform, khaki jacket, looking at viewer, indoors, library, open book
Negative prompt: EasyNegativeV2, fewer fingers, extra fingers, extra legs, signature, watermark, username, blush, torii, kimono, extra tail

さらに多人数を生成するため、Tiled Diffusionを設定します。Promptの内容をタイリングで繰り返すことで、さらに生成人数が増えます。
