It's a peculiar one to say the least. It's based on a single image by Hisano Motoki of the Precure characters in a particular scenario. It's essentially a single image lora.
Most obvious use is nsfw (particularly recreating the image used in trainig), but it works great for sfw generations as well.
The trigger word is supposed to be:
mot@inom3gmi
You can also use "aino kaori", but I'm unsure if it changes anything.
Use other words to recreate the character more, namely: purple hair, red eyes.
