Character LoRA for Claude Sirius (クロード・シリアス) from The Classroom of a Black Cat and a Witch (黒猫と魔女の教室 / Kuroneko to Majo no Kyōshitsu)

Covers both of his forms — the human magician and the black cat.

Trained on Illustrious. Works with most Illustrious / NoobAI-based anime checkpoints.

Trigger words

claude sirius - Human

claude cat - Cat

Both forms can appear in the same image. Just include both triggers and the model will place them together.

I generate with the usual supporting tags in the prompt 1boy, male focus, solo, black cat, animal focus, no humans and so on depending on the shot) and the forms stay clean and separate that way — no bleeding between them in my testing.
