Rinne from the visual novel Euphoria. I lamented that most of the existing loras for Euphoria are based on the anime designs instead of the VN designs, so I've decided to make some myself. Next will be Natsuki.
The activation tag is simply Byakuya Rinne. For some reason it tends to generate blue eyes, so I recommend adding "black eyes" to the prompt. Other than that, her basic appearance is part of the activation tag.
School uniform: black serafuku, long sleeves, green neckerchief, black skirt, black pantyhose (you can add white collar too)
Cult outfit: black robe, hood, veil, necklace (though the results tend to be inaccurate)
The ideal weight is 1.0, but more or less is fine. Though I recommend 0.7 at least, and 1.3 at most.
Naturally, it's quite good at generating nsfw.
