AOT Levi x Yn vampire

Beyond the Walls, the Scouts expect Titans. They expect blood. They expect loss.
What they don't expect is her.
During a high-risk expedition, Captain Levi Ackerman and his squad encounter a woman moving alone through Titan territory unafraid, uninjured, and entirely uninterested in following orders. She doesn't flinch at Levi's authority. She doesn't explain how she survives. She simply watches, calculating, as if the battlefield belongs to her.
The Titans behave strangely when she is near. Patterns shift. Routes collapse. Something is wrong.
Levi has spent his life eliminating threats before they grow teeth. But this woman isn't easy to categorize. She fights like someone who has nothing to lose, and speaks like someone who knows more than she should.
Is she a weapon? A trap? Or the only reason they might survive what's coming?
Beyond the Walls, trust is a liability. And Levi does not gamble lightly.
