Kivotos Story Style — Blue Archive Art Style LoRA (Illustrious)

A style LoRA that recreates the look of Blue Archive's official story illustrations and in-game PV. It aims for the game's signature feel: soft cel shading, bright pastel colors, clean thin lineart, and the airy, sunlit atmosphere of Kivotos.

It is not a character LoRA. It changes how things are drawn, not who is drawn, so it works with Blue Archive characters, original characters and characters from other series alike.

▶ Trigger word

bastory

Put it at the start of your prompt. Leaving it out still gives a partial style effect, but the full style needs the trigger.

━━━━━━━━━━━━━━━━━━━━

▶ Recommended settings

- Base model: Illustrious-based checkpoints (tested mainly on WAI Illustrious v17)

- LoRA weight: 0.8 – 1.0

– Lower it to 0.6 – 0.8 if you stack it with character LoRAs or other style LoRAs

- Sampler: Euler a, 25 – 30 steps

- CFG: 4 – 5. Higher values tend to oversaturate and harden the lines.

- CLIP skip: 2

- Resolution: 1344×768 or 832×1216 (SDXL-native sizes)

▶ Hires fix (recommended)

- Upscale in pixel space, e.g. with 4x-AnimeSharp, then scale down to 1.5× of the base size

- Second pass denoise: 0.35 – 0.45

- Latent upscaling can warp straight lines such as desks and buildings, so pixel upscaling is preferred.

━━━━━━━━━━━━━━━━━━━━

▶ Prompt tips

- For Blue Archive characters, use the Danbooru name plus the series tag:

e.g. "arona (blue archive), blue archive"

- Adding "halo" helps the characters keep their halos.

- Scene tags like classroom, city street, school rooftop, blue sky and sunlight match the style best.

Example prompt:

bastory, masterpiece, best quality, 1girl, arona (blue archive), blue archive, halo, smile, school uniform, classroom, window, sunlight, blue sky, looking at viewer

Example negative:

lowres, worst quality, bad quality, bad anatomy, bad hands, extra fingers, blurry, jpeg artifacts, watermark, signature, text

━━━━━━━━━━━━━━━━━━━━

▶ Known limitations

- Small hands and faces in wide shots can get messy. A face/hand detailer (e.g. ADetailer / FaceDetailer) fixes most of this.

- Very crowded backgrounds may lose detail. Tile upscaling at low denoise (0.25 – 0.3) helps.

- Results vary from seed to seed. Generating a few previews before upscaling is recommended.

- Night and dark indoor scenes are less polished than daytime scenes because of the training data.

━━━━━━━━━━━━━━━━━━━━

▶ Training details

- Trainer: OneTrainer (SDXL LoRA)

- Dataset: about 85 images from official story illustrations and PV frames, captioned with WD14 tags plus the trigger word

- Two separately trained versions, one focused on illustrations and one on illustrations plus PV, merged (0.5 / 0.4) to balance the "Blue Archive feel" with stability

- Merged rank: 64, fp16
