Ashes and Wings (Eren x OC)

Melody Ackerman was never meant to survive the war.
Levi's younger sister and the only light left in his world, she fights with blades in her hands and a song buried deep in her bones.
When she begins to experience strange flashes of the future - and of a monstrous version of Eren Yeager - everything changes.
Caught between the boy she loves, the brother who would burn the world to protect her, and a fate that loops through death and memory, Melody must decide what she's willing to destroy... and who she's willing to become.
This is a story about love that refuses to die, grief that won't let go, and the final moment before everything falls.
