I trained this lora on volume 8-30 of Berserk. I had to break it up into four chunks to get every page in there. I got a lot of variety of information, however the characters bleed in very hard, especially Gutts, at 1. As such, you may want to turn it down to .8 or .6 depending on your use.

The style shows through a bit by default, but manga or monochrome will really bring it out: Monochrome especially.
