Trained on the manga Reincarnation Colosseum, this lora excels at hatching and linework. It almost works by default, but you can turn it up with manga and/or monochrome. I overtuned this one a bit searching for good detail work, so when calling it with manga panels and characters might become overpowering. In those situations I recommend turning it down to about 80%. Also, as the manga is a bit lewd expect clothes to become a bit racy by default.
