Trigger it by using: yuina, red eyes, <lora:yuina:0.5>.

A little bit overfitting so use a smaller weight ~0.5.

This model is trained on a dataset built on game assets and some screenshots of Yuina-senpai's 3D model. Unfortunately, it could be hard to change Yuina-senpai's clothes; the dataset is relatively monotone (but you can still make her bottomless).
