No trigger word needed for this lora. I recommend using 0.9 strength as the model is slightly overtrained.
v2 is far from perfect, but better in every single way than v1. It still hasn't learned this style perfectly and focused a bit too much on background instead of characters.
This dataset really needs good reg images for anime + a trigger word for it. But I don't have that to train it for now, so it will have to wait.
