Synopsis:

Reincarnating into the Harry Potter universe should have been a dream come true. But for [FMC's Name], it was a playground for chaos.

Gifted with a magic ability that lets her steal anything without anyone realizing it’s gone, she turned the wizarding world upside down—stealing the Philosopher’s Stone, dismantling Voldemort’s plans, and leaving even Dumbledore utterly baffled.

By the time she left Hogwarts, history had been rewritten beyond recognition.

But her journey doesn’t end there.

With nothing left to challenge her, she sets her sights on a new magical world—one just as full of legends, prophecies, and untold power.

And once again, no one will ever suspect a thing.

The Phantom Thief of Fate

Hogwarts was peaceful. Too peaceful.

With no dark lords left to mess with, no grand prophecies to break, and no ancient artifacts to casually pocket…

Because a bored me meant trouble for the universe.

I had no real reason to be in the Room of Requirement.

But old habits die hard, and the room always had interesting things.

Not just any door—this one didn't belong here.

It wasn't Hogwarts magic. It wasn't wizard magic at all.

I tilted my head. "Well, that's suspicious."

The moment I stepped through, I felt it.

The kind that whispered secrets and laughed at the laws of reality.

Colors blurred. Time folded. The universe rewrote itself—

The sky above me was too vast, too bright.

The air hummed with power, thick with an energy I'd never felt before.

I took one step forward, feeling the new world settle around me.

"Well… let's see what kind of mess I can make here."
