This lora is from the enemy Fairy from the game "Lost Case: monster Girl Takeover". Unfortunately, the game has been abandoned, but the creator zolvatory continues to stream about it, adding characters and so on.

so the lora make the character properly you need to use this prompt:

1girl, fairy, light brown hair, diadem, antennae, blue tie, white vest, black shirt, blue butterfly wings, striped black and blue stocking, blue skirt,

Maybe I'll do the other enemy characters from the published demo
