No trigger word is needed for this LoRA. Though using something like This is a absurdres, high quality, aesthetic masterpiece cinematic anime artwork. or something around those lines helps Chroma produce better images.
I invite you to add other LoRA to make the image quality better. The showcase images were generated with a very basic workflow (comfy workflow is included in the images). You can easily get better result if you try a bit harder, this is only meant to showcase the effect of the LoRA alone.
I recommend setting the LoRA strength at 0.9 for the best results.
