Keep in mind that settings may vary slightly between different versions. See below for more details.
When I tested this with different checkpoints and LoRAs, it seemed to work quite well.
Illustrious:
A LoRA weight of 0.9 works great, though you can adjust the strength as you prefer.
Prompts I usually used:
sajuna_inui, medium hair, pink hair, hair between eyes, black flower hairclips, pink eyes, serafuku, school uniform, red sailor collar, short sleeves, yellow ribbon, black vest, red skirt, pleated skirt, black thighhighs,
