High-fidelity character LoRA for Senko-san from The Helpful Fox Senko-san, trained for Anima.

Built from a high-quality synthetic dataset of 598 captioned images generated with NovelAI 4.5 Curated. Designed for txt2img, img2img, inpainting, and character replacement workflows.

The trigger word is:

senko_san

What This Model Does Best

• Character identity: Reproduces Senko's recognizable face, amber eyes, short layered golden-blonde hair, fox ears, fluffy fox tail, hair ornament, and anime appearance.

• Outfit flexibility: Maintains her identity across dresses, casual clothing, jackets, hoodies, kimono, and other outfits.

• Natural-language prompting: Works well with descriptive prompts suited to Anima's Qwen3-0.6B text encoder.

• Scene flexibility: Handles indoor, outdoor, traditional, modern, daytime, sunset, and nighttime environments.

• Img2img and inpainting: Can apply Senko's identity while preserving an existing composition, clothing, pose, lighting, or background.

For stronger character influence, LoRA weight 1.2 can also work well.

Prompting

Anima uses Qwen3-0.6B for text conditioning, so descriptive natural-language prompts work well.

Instead of relying only on short tag lists such as:

senko_san, 1girl, fox ears, blue dress, beach, sunset, sun hat

you can describe the image more directly:

senko_san in an anime-styled image. She is standing on a beach at sunset wearing a light blue long dress and a sun hat. The view is from the front, with warm golden-hour lighting and colorful clouds behind her. Her fluffy fox tail hangs naturally to the side.

Tags and natural language can also be mixed together.

A short negative prompt is usually a good starting point:

worst quality, low quality, blurry, deformed, text, watermark

More targeted negatives can be added when needed for ears, tails, anatomy, or other recurring problems.

Example 1 — Beach Sunset

Prompt:

senko_san in anime styled image. Breathtaking beach sunset, close-up of senko_san. Golden hour sunset. senko_san wearing a light blue long dress. View is from the front facing senko_san. Her tail is to the side and down. Some clouds in the sky. The sunset sky is awash in various colors. She wears a sun hat. Use senko_san’s recognizable face, short layered hair, fox ears, fluffy fox tail, and proper colors. Hair color: #F2B93B to #F6C84A with highlights around #FFD86A. Fur color: #EFB53A to #F5C246 with soft cream tones and white fur accents. Keep the result warm golden-yellow, not pale and not overly orange.

Negative prompt:

senko_san in a cozy anime-styled modern kitchen during the morning. She is wearing an oversized white hoodie and holding a warm coffee mug. Gentle morning sunlight enters through a nearby window and softly illuminates her face and hair. Keep senko_san’s recognizable facial features, amber eyes, short layered golden-blonde hair, fox ears, fluffy fox tail, hair ornament, and proper golden-yellow coloring.

Negative prompt:

Example 5 — Img2img / Inpainting

Prompt:

Change the character into senko_san while preserving the original image's pose, camera angle, clothing, lighting, and background composition. Give her senko_san’s recognizable face, amber eyes, short layered golden-blonde hair, fox ears, fluffy golden fox tail, and characteristic hair ornament. Keep the expression natural and make the character blend cleanly with the existing image.

For face or head replacement:

Replace the character’s face and head with senko_san. Give her senko_san’s recognizable facial features, amber eyes, short layered golden-blonde hair, fox ears, and hair ornament. Preserve the existing body, clothing, pose, lighting, camera perspective, and background.

Negative prompt:

worst quality, low quality, blurry, multiple tails, cat ears, human ears, deformed face, bad anatomy, extra ears, extra limbs, text, signature, watermark

Text Encoding

Anima uses Qwen3-0.6B for text conditioning.

Natural-language descriptions are recommended for detailed control over clothing, poses, composition, lighting, environments, colors, and character details. Tags can still be used on their own or mixed with descriptive text.

There is no Clip Skip setting.
