Description

This is a test LoRA model trained on HunyuanVideo using my favorite character.

This LoRA depicts the Character Suou Amane from Grisaia series.

Trigger word: "suou_amane, red hair, long hair, blue eyes, "

Example: "suou_amane, red hair, long hair, blue eyes, an anime girl is looking at viewer. She is wearing school uniform, and smiling to viewer."

Usage Notes

Since this model was trained with a resolution of 960x544, it is recommended to generate videos in similar landscape aspect ratios for optimal results.
