NACCHAN — SDXL Character LoRA [Illustrious XL 2.0] ============================================================ Nacchan by Ohisashiburi — the tomboy with dark skin, messy black hair. She wears a black jacket with red stripes over her uniform, always has bike shorts peeking out from under her skirt, and she have cat ears Micchan's partner — literally. These two are meant to be together. Check my other LoRA if you want the full set. 🏷️ TRIGGER + ANCHOR ============================================================ nacchan, 1girl, dark skin, short hair, black hair, tomboy, school uniform, black jacket, skirt, shorts under skirt, choker ⚙️ RECOMMENDED SETTINGS ============================================================ LoRA weight: 0.7 to 1.0 I run her at 0.85 most of the time. At 1.0 she gets extra dark and moody — fitting. CFG: 5 to 7 Higher CFG brings out the darker skin tones. Lower makes her softer — not really her vibe. Sampler: Euler Ancestral or DPM++ 2M Karras Steps: 25 to 35 Resolution: 832×1216 (2:3 portrait) or 1024×1024 ❌ NEGATIVE PROMPT ============================================================ lowres, bad anatomy, bad hands, extra fingers, missing fingers, blurry, monochrome, greyscale, blue skin, grey skin, clothes, clothing, shirt, jacket, underwear, speech bubble, text, watermark, censored ⚠️ KNOWN ISSUES ============================================================ Nude prompts can leak clothing. Because almost all training images have her in uniform, the LoRA learned a strong outfit association. For nude scenes, add "clothes, clothing, shirt, skirt, jacket, uniform, shorts, underwear" to negative and bump weight to 1.0. Speech bubble bleed is real — nacchan trained on manga-style images and text bubbles can leak through even with "speech bubble, text" in negative. If they persist, add "manga panel, screentone, comic, speech bubble, text, dialogue, letterbox" for a more aggressive block. Not all Illustrious merges work equally well. She's solid on base Illustrious models and bismuthIllustrious (my top recommendation — best results at weight 0.7-1.0). Some merges may produce inconsistent colors or weak character recognition. If a merge isn't cooperating, switch to bismuthIllustrious. At very high weights (above 1.2), the black jacket and shorts can dominate even outfit-swap prompts. Drop to 0.8 for outfit flexibility. 📊 TRAINING DETAILS ============================================================ Base Model: Illustrious XL 2.0 (illustriousXL20_v20) Network: LoRA — Dim 32 / Alpha 16 Epochs: 10 Batch Size: 2 Optimizer: AdamW with Cosine LR Resolution: 1024 (bucket training, min 256 max 2048) Total Steps: 2,850 Final Loss: 0.0629 Captions: WD14 Tagger ConvNeXt v2 ✅ COMPATIBILITY ============================================================ Tested and consistent on Illustrious XL 2.0. Should work on most Illustrious-based checkpoints (NoobAI, Hassaku, WAI). Not tested on Pony or SD 1.5. When stacking with other character LoRAs, bump nacchan's weight to 1.0-1.2 — she can get overwhelmed at equal weights. 💡 TIPS ============================================================ She's a tomboy — lean into it. "scowl", "annoyed", "looking away", "hands in pockets" all work naturally. She's not the smiling type. When she does smile, it should feel earned. The bike shorts under skirt is her signature look. If you swap outfits, add "bike shorts, shorts under skirt" to keep the vibe. It's part of who she is. For the best dark skin results, pair with checkpoints that handle diverse skin tones well. Some anime checkpoints wash her out. 🎨 COMMISSIONS &amp; SUGGESTIONS ============================================================ Got a character you want turned into a LoRA? Drop a comment or DM. I do commissions — character, style, outfit, whatever you need. I'll work with you on dataset and training to get the result you want. Check my profile for Michan — her partner. They're meant to be together.
