Sei Tenshi Patina from a one-shot segment of a ero manga called Love A by NEO'GENTLE. Very unique style for manga given the detail, shading style, and surprising lack of censoring...The Lova A story stands out to me for two stories - one the titular Love A, and the other Holy Angel Patina. Both involved heroine corruption. The Patina story is an angel corruption story that I have yet to see rival in its pacing, style, and horror bits. It also does not end with the total defeat of the heroine - a bit of cliff hanger - the reader never sees her completely corrupted.

Needless to say I love this one. The lora was built with black and white images from the manga. SD fills in the rest. The artist's style does carry through but is more detailed and consistent with the original black and white. This can be triggers by putting monochrome in positive or negative prompts.

Overall there are a lot of prompts and combinations - I wanted to detail as much of the transformation sequence as possible - but given the rare material some aspects are stronger than others.

Nurse is very strong prompt given the character theme it is advisable to put "Nurse" and "Hospital" in the negative.

"tentacle background", and "tentacle lair" help set the theme from the manga.
