This is Takanashi Ouka from Saimin Kanojo Kanojo no Haha Takanashi Ouka.

Her prompts are:

sakakaouta, solo, purple eyes, black hair, long hair, bangs, single hair bun,

Version 1 notes:

I'm quite happy with this. I'm still getting more than one person if you don't typle solo. While I try to avoid using dataset with more than one person, sometimes there isn't a lot to work with so I think that is the reason why some characters I trained resulted in multiple persons if you don't use the solo prompt.
