This lora should provide Ryoko Otonashi, Yasuke Matsuda, and Junko Enoshima. Likewise, it should be able to mix and match them in the same image. In theory it should do OK with both tags and narrative descriptions. However, on Illustrious tags will generally work better. On Chroma a mix of natural language and the most important tags seems to work the best. And Z-Image tends to perform best with this lora using a similar strategy as Chroma.

Z-Image notes: This was trained on Z-Image Turbo, I'll have an update eventually retrained on the base model.

Junko Notes: Neither the Chroma or Z-Image loras do an especially good job with Junko. I'll have a dedicated Junko lora eventually.

Important note on the Chroma version

The Chroma version is in that "kinda ok" limbo. Good enough to release, but I want to put together an updated version in the future. Junko's hairclips, Ryoko's jacket design and color, it all tends to drift a lot. Though I do find that the Chroma lora does tend to benefit with Junko prompts by combining it with my Chroma Danganronpa anime style lora.

Both together: danganronpa/zero, danganronpa_(series), matsuda_yasuke, otonashi_ryouko, 1boy, 1girl, ahoge, black_hair, grey_eyes, long_hair, necktie, red_hair, school_uniform, very_long_hair, skirt, gray skirt

Junko Enoshima narrative: Junko Enoshima has blond hair in two twintails held together with a white bear hair clip on her right and a black bear clip on her left. She is wearing a black cardigan over a white dress shirt open at the top, a red bow on the left of her chest, a short red pleated miniskirt, black platform boots with red laces, and has long red nails. Junko has light blue eyes.

Coloring for Ryoko's clothing tends to vary a lot in the official art so I'd advise just playing around with tags to tweak it to what you'd like.

You 'might' be able to push it into anime styles in the 1.x branch (so far this is only for Illustrious) by adding either of these to the prompt:

This is an anime screencap from Danganronpa 3.

This anime screencap is from Danganronpa the Animation.

I've made some modifications in the 2.x (used starting with the Chroma and Z-Image versions) and while the previous methods of style use can still be used I'd advise also adding one or more of these:

danganronpa_1_(anime),

danganronpa_3_(anime)_(style)

super_danganronpa_2.5:_komaeda_nagito_to_sekai_no_hakaimono_(style)

However, the style application came out fairly weak in the Chroma lora.

I think the lora came out OK in the end, but the process was hampered by lack of training data. There's really not a huge amount out there, offiical or fan made, of these two. I mean Aiko Umesawa had more screen time in the Danganronpa 3 anime than they did. I wound up mixing a combination of the highest quality unofficial art and all of the official art along with selections from my other Danganronpa loras for both characters and the anime styles. The hope is that by going that route I'd get just enough bleed-in from the other Danganronpa stuff to balance out the distinct look of the Danganronpa Zero art style to get it pushed closer to the normal Danganronpa style. Which is also why Junko features heavily in this lora's dataset. I figured that was a solid choice for a base in the anime and sprite styles to push closer to.
