This is Togano Kaho fro Bijukubo. She is the protagonist's aunt, who also acts his adopted mother.

Her prompts:

solo, bijutoka, mature female, green eyes, purple hair,

Version 1 notes:

Unable to test with checkpoints, site is pretty messed up today. At strength 1 and with basic prompts the image generated looks quite close to the source material so I consider this a success.

Please include solo in prompts, for the 2nd time I seem to mess up and cause 2 girls to appear if you don't use the solo prompt.
