<h1 id="overview">Overview</h1>Character-LoRA is an SDXL-based character LoRA created to reproduce the <code>BACKGWA</code> character using a copyright-conscious synthetic image dataset.This LoRA was developed as part of research on whether a character LoRA can be trained without directly using original character images or artist-created works as training data. Instead of collecting or reusing human-made artwork, the training dataset was constructed from AI-generated synthetic images based on structured character descriptions.The full research document, methodology, instruction template, and JSON schema are available in the GitHub repository: <a rel="ugc" href="https://github.com/BackGwa/Character-LoRA">BackGwa/Character-LoRA</a>Through this approach, the research examines a workflow for constructing character LoRA models while reducing dependence on original images and considering copyright, training rights, artistic style, and intellectual property. <h2 id="disclaimer">Disclaimer</h2><ul><li>This LoRA may be used freely for the user's own creative purposes.

A total of 80 synthetic images were generated as training candidates, and 48 images were selected for the final dataset based on consistency and quality.To prepare the character description used for image generation, the original character image and supplementary information were provided to the locally executed <a rel="ugc" href="https://huggingface.co/google/gemma-4-E4B-it">gemma-4-E4B-it</a> model. The analysis used predefined instructions and a structured JSON schema to describe the character in a form suitable for subsequent synthetic image generation.The selected synthetic images were then labeled using GPT-5.5. The labels describe visible attributes such as expression, pose, composition, and other image-specific details used during training.The LoRA was trained using <code>sd-scripts</code> on the SDXL-based <a rel="ugc" href="https://huggingface.co/BackGwa/LUMIERE-Q">LUMIERE-Q</a> model.<h2 id="research-repository">Research Repository</h2>The research document and related materials are available at: <a rel="ugc" href="https://github.com/BackGwa/Character-LoRA">BackGwa/Character-LoRA</a><h2 id="license">License</h2>The LoRA model is released under the CreativeML Open RAIL-M license.

Character-LoRA (BACKGWA)

Character-LoRA is studied based on the Anima model.<ul><li>The LoRA was trained using the Anima base-v1.0 model.</li><li>The labeling was revised to better fit the Anima model. This includes both natural-language prompts and tag-based prompting.</li></ul>
