Prototype
This is a fairy-like LORA from Kantai Collection, but it's not very good.
It seems that strength should be around 1.3.
It seems to be good to use chibi and chibi only together.
The normal character and the fairy-like character are often output together.
Try increasing the strength, or increasing the strength of the chibi only prompt.
It may also be effective to try reducing the image size.
I tried it out, and if I reduced the image size and output it, it was output correctly without increasing the strength.
A size of around 400*600 tends to work well.
When generating with civitai, the image size is too large, so it tends to generate realistic characters along with the chibi characters.
