Side note: There is another Pony version of this but it didn't work as well for me so I just redid my own. Please go check it out if mine doesn't work for you.
Hiya Papaya! Got another obscure waifu for you. Madaraki Fran from the Franken Fran manga by Katsuhisa Kigitsu. https://en.wikipedia.org/wiki/Franken_Fran
Fair warning the manga has some body horror and the cover art is very misleading.(The actual contents are low in fan service.)
FYI She canonically has detachable extra arms so if you get more than two arms without asking for it, that's not an issue. :)
Strength of 1 seems fine. Used https://civitai.com/models/15886/sardonyx-blend for the example images.
Trigger word: madaraki_fran
More or less canon look: long_hair, blonde_hair, blue_skirt, labcoat, red ribbon, white_shirt, extra arms
I had issues with colors bleeding onto other clothes but that's likely a skill issue on my part.
