Attack on Titan: Revenge on Marley (Witch Version)

'They didn't tell me everything was going to start this soon.'

Nine years after being sent from Paradis Island to live with her aunt Alanis in Marley and being placed in combat training to infiltrate the Marleyan military, Valkylie 'Kylie' Mason is wedged between fulfilling her mission for the restoration of Eldia and following what she was trained for, assisting her Marleyan comrades and the further advancement of Marley's empire.

Almost completely forgetting the main reason why she's there in the first place while being occupied as one of the most revered turret gunners on the battlefields, she returns from the war at Fort Slava to an impending issue that is reminded to her by Alanis and her coven. The forthcoming actions of someone else from Paradis Island, the inheritor of the Founding Titan, Eren Jaeger.

Realizing and eventually accepting the sealed fates of her comrades, Marley, and the world around them after being forced to return to Paradis, she quickly goes through with her aunt's set plan before The Rumbling, leaving the Marleyan military and her comrades to fend for themselves against Paradis.
