Katsuragi Sara (葛城 沙羅) from the game Zettai Junshu ☆ Kyousei Kozukuri Kyokashou!! (ぜったい遵守☆強制子作り許可証!!). Trained for 800 steps from a variety of in-game images. Haven't found any limits on the tests, but was trained on some NSFW so take precautions if needed. Adding "loli,young" to the negative helps with body shape. If you want to recreate the god-awful anime version, then make an image and then wildly move your head around until you get violently ill (seriously what the heck Gold Bear)

Prompt

KatsuragiSara,silver hair,red eyes,short hair,black hair ribbon
