Recommended to use either prefect pony or autismix, recommended strength at 0.6. Other than prefect you may get some white gradient effect when using any other checkpoints. Unfortunately that is probably due to the training dataset.

In terms of aesthetics, autismix is closer to the source material but other than ?????? acts you will most likely get the white gradien effect.

Her prompts are:

Shiramizu_Kasumi, black hair, low ponytail, purple eyes, long hair
