触发词只有 imsgi nui。添加 chibi 和 character doll 似乎没有帮助也没有坏处。
如果你希望正常人和ぬい同框，我建议使用inpaint的方式。
imsgi nui 缩写自 idolmaster gakuen idolmaster nui。
The trigger word IS ONLY "imsgi nui." Adding "chibi" and "character doll" seems NEITHER helpful NOR harmful.
If you want regular people and nui to appear together in the frame, I recommend using the inpaint method.
imsgi nui is short for idolmaster gakuen idolmaster nui, in case you're curious.
