[Western Crossover] A Gotham Survival Guide

[Highlight: Slow updates. This story will never be locked behind a paywall, so please be patient and keep following along. The timeline and plot have been heavily reworked, so let your imagination run free.

OOC throughout. Please don't offer writing advice, and don't get hung up on the logic. This is self-indulgent writing; logic has been eaten by me. Just enjoy reading. If you aren't enjoying it, run for the hills using the back button!]

I, Olivia Wayne, am now standing at an intersection in the Muggle world, pondering my life.

I swear, all I did was sprinkle Floo Powder. Why is the destination system so unreliable? Dumbledore, I really wasn't trying to dump this mess on you this time!

Wait, why does the man on the newspaper, with women draped over both arms, look a little like me?

Can someone tell me why I suddenly have a brother in his thirties or forties when I'm only fifteen?

My brother isn't even married, but he already has a son?

Holy crap, you have more than one son? I only have one owl!

I heard Gotham has a vigilante called Batman. But does covering half your face really count as a disguise?

Bro, is that you?

After reading so many Batkids stories, I decided to give Bruce a troublesome (not) little sister to make his life miserable.

She's seven years younger than Bruce. She was transported to the Harry Potter world when she was about two, so she has few memories of her own family. Dumbledore found her, discovered that she had magical talent, and brought her to Hogwarts to study. Because time passes differently in the two worlds, when she returned, Tim had already become the popular Robin.

This is the story of Olivia, a morally chaotic fun-lover studying in Slytherin House at the famous wizarding vocational school Hogwarts, who smashes down the Ministry of Magic's door and then accidentally travels back to her happy home. (Not really.)

Dumbledore, believe me. That door cracked on its own. I didn't even touch it with my wand!

I really didn't run away on purpose. I sprinkled Floo Powder and ended up at an intersection in Gotham. Your transport network needs maintenance, Ministry of Magic. I want to file a complaint!

No CP, you know the deal. The female lead is single, so how can everyone else be dating? There's so little to read, so I decided to write my own!

Coming soon: The Witch's Journey

A witch possesses great power, extensive knowledge, and the appearance of a human woman.

Are they human, devils, or neither?

Humans revered, pursued, and feared the witches' power. Finally, during the witch hunts of the Middle Ages, humanity purged witches from its history, and their existence faded into obscurity.

However,

A pair of beautiful, translucent blood-red eyes, like pigeon-blood rubies, quietly opened. Long black hair, as dark and lustrous as satin in the night, fell from midair. Slender, pale fingers gently pressed down on a bomb that was one second away from exploding.

Time stopped.

The girl asked the young man before her, "You who awakened me from the abyss, what is your wish?"

Jinpei Matsuda, who thought he was about to die and was racing against time to type his last words on his phone: "?"

Are you crazy, or am I?

She is the last witch in the world, sleeping in the abyss where dream and reality meet.

In my past, my future, or my present, was there ever a trace of you?

Mainly Detective Conan and Jujutsu Kaisen.

The history books once recorded:

[Witches have no hearts, tears, or feelings. Only desire can move them.]

Theme: Life needs a little sweetness.
