LoRA of Ibarazaki Emi, the legless track team girl from Katawa Shoujo. This is a preliminary version that doesn't deal with her prosthesis well (and in fact leaves them out entirely until specifically prompted).
I'll experiment with this one a bit more at a later point to try and get it to be more reliable, but the generations at least fit the overall character pretty well. Using "amputee" and especially "prosthesis" or "prosthetic legs" should result work okay though, just don't get your hopes up on getting proper running prostheses.
