Short version:

Use the manga+color for color illustrations and general usage. Use the manga-only version for creating images as close to the manga in general. If you have to download one LoRA, the manga+color will, of course, be a bit more versatile.

Update 12-2-25: I released an alternative version with only manga panels. I went back and gathered a few extra images from chapters 66-69; in other words, the manga-only version covers appearances of her from chapters 66-81. The main version still works great, but I noticed her eyes' shading blends with the manga and color images, so the manga-only version should help with producing more faithful-looking images.

A follower on X recommended this manga to me earlier this year. I like Lemon a lot now since checking out the series, so why not? Here's a LoRA of her I did for fun. I might do Natsumi Kogahara later, as well. This LoRA is based on color illustrations and on some appearances of her in chapters 70-81.
