Konrad Curze, the Night Haunter himself, finds his way into Gotham through a warp storm — and mistakes a certain agile thief in black for a Callidus Assassin.

Instead of an execution, he finds fascination.
Instead of prey, a challenge.

I was first thinking about Curze × Harley Quinn, but I thought she would be way too loyal to the Joker. Also, you can generate perfect pictures of Harley without any LoRA at all.
