[Western Crossover] The Killing Curse Is Banned in Gotham

A Wizard Arrives in Gotham

In a city full of all kinds of people, the arrival of a wizard shouldn't be a problem.

That is, until Batman discovered that the kids in his family had started copying her.

"What is this?"

"Kale."

Batman narrowed his eyes at the leafy vegetables chasing members of the Riddler gang and biting them from behind. "Say that again. What is this?"

"Um... Chinese biting kale?"

"..."

"Can someone explain this?"

Batman stared at the very real pig's face on Professor Pyg's head, his anger simmering.

"It's just a little spell, Bruce. I was being nice and saving him the trouble of wearing a mask."

"..."

Poisonous tentacles flying through the dark, mandrakes sobbing nonstop in a corner, a caped fighter surrounded by thunder, magical fireworks exploding in all directions, and... manure bombs gradually getting out of control in the sewers?

When he opened the surveillance feed on the Batcomputer and saw that familiar green light flashing, he finally snapped:

"Eleanor! Get out of Gotham!"

Eleanor: A transfer student from Hogwarts, heir to ancient magic, protector of the wizarding world, and former Chosen One.

Her motto in life:

If an Avada Kedavra only kills one person, then that Avada Kedavra was wasted.

There's nothing an Avada Kedavra can't solve. If there is, just add a Cruciatus Curse.

As long as she doesn't want to leave, no one can make her leave Gotham.

Please Note:

1. The protagonist is the player character from Hogwarts Legacy, with a rather peculiar personality (in short, a bad one).

2. Although this is categorized as romance, the protagonist will not have a romantic relationship with any member of Gotham's Bat-family. She has her own love interest, a character from Hogwarts Legacy.

3. Age adjustments.

4. A mountain of headcanons, lots and lots of them.

5. A slow-burn slice-of-life story. Proceed with caution if that's not your thing.

6. Apologies for all the OOC.
