AI ART CHARACTER LORA
AIキャラLoRA
LoRA (Low-Rank Adaptation) is a fine-tuning technique that lets you train a small adapter on a specific character's reference images, then apply it to any AI image generation to lock in that character's features. It's the technology that makes consistent AI anime characters possible.

Hand-picked illustrated stories
Before LoRA, AI image generation had a character-consistency problem. Generate Luna twice and you'd get two different girls — same general aesthetic, different faces. The full model couldn't 'remember' specific characters.
LoRA solved this. The technique trains a small adapter (a few hundred MB instead of a full multi-GB model) on 20-50 reference images of a specific character. When you apply the LoRA to a base model during generation, the character's features get locked in — same face, same hair, same body proportions, every time.
Every Neon Kisu character has a trained LoRA. Luna's silver-lavender hair, violet eyes, and hair-over-one-eye are locked in by her LoRA. Hana's crimson twin-tails and black ribbons are locked in by hers. The result: thousands of generated images that all show the same recognizable character.

Frequently asked questions
What does LoRA stand for?
Low-Rank Adaptation. It's a parameter-efficient fine-tuning technique originally developed for large language models, then adapted for image generation. The 'low-rank' refers to the math — the adapter modifies only a small number of model parameters, which is what makes it small and fast to train.
How many reference images do you need to train a LoRA?
Typically 20-50 high-quality images. More isn't always better — too many similar images can cause overfitting (the LoRA only generates the same poses/angles as the training data). The Neon Kisu LoRAs are trained on 30-80 carefully-curated images per character.
Can I train a LoRA myself?
Yes — tools like Kohya SS, OneTrainer, and others let you train LoRAs on a consumer GPU (8GB+ VRAM recommended). The training takes 30 minutes to a few hours depending on settings. Online services like Civitai also offer LoRA training as a paid service.
What models does Neon Kisu's LoRAs work with?
Most of our character LoRAs are trained on Illustrious or Pony Diffusion variants — popular anime-style base models. Some LoRAs work with multiple base models; others are specific to one.
