The Girl Who Flew (SNK/Attack on Titan/Levi x OC)

"Fear has two meanings, forget everything and run or face everything and rise!"

Thalia Gatö was a fearless young girl who lived with her mother behind the Wall Maria in Shiganshina District. Thalia's biggest dreams were to fly like the birds that passed over the walls whenever they pleased. Convinced her father died, the daughter of Hitomi Gatö, the rumored 'goddess of war' had settled. It had been 100 years since the rumored 'Titans' ascended havoc upon the planet. Humanity is on the brink of extinction. In the blink of an eye, the peace and serenity is snatched away from Thalia, along with her mother who only manages to shove a bag into Thalia's arms and throws her into a boat that leads to safety.

Five years have passed and Thalia is a young woman clutching onto a feeble crush and a shell shocking dream. Thalia's mother left her answers after her passing. Her father is alive and well. In fact. She is the daughter of Erwin Smith, Commander of the Scouts. But what commander would listen to a pathetic girl, nor some tall tale? Biting down her words, she sets her heart, soul, and mind into becoming the strongest ablest Scout to hopefully one day reveal herself to Erwin as his long lost daughter.
At the same time, she's holding back an embarrassing crush for the mysterious, brooding Captain Levi. All this horror, bloodshed and death who will be next? Thalia knows she needs to speak now before she's the next one being marked off as dead. She can't let these secrets die with her.

Maybe things will start actually looking up in these horrid times? They do say love conquers all.
