This is a 2 in 1 character couple LoRA for Hanako-kun x Nene Yashiro (花子くん x 八尋寧々) from Toilet-bound Hanako-kun.
The examples are using LoRA weight=1 and highres fix ESRGAN_4x with denoising strength=0.5 or 0.4.
Hanako character trigger: hanako yellow eyes
Hanako default outfit: black jacket gakuran
Hanako optional outfit: hat
Nene character trigger: nene red eyes
Nene default outfit: white dress sailor collar puffy sleeves
The two characters can be triggered separately like you are using single character LoRAs. If you still get both characters, you can add solo in prompts.
To trigger both of the characters at the same time, in addition to character triggers, you may need to specify some interactions, such as hug, kiss, back-to-back or side-by-side.
Put nene trigger in prompt first then hanako can increase the chance for correct eye colors.
It works more consistently in anime models comparing to realistic ones.
