After the Marleyan Empire fell and the Eldian Empire was restored, Levi overtook the throne of Marley, while he married Hanji later on, selecting her as the Queen of Marley.

Eren and Mikasa moved to Thunder City, Arcadia, where they would marry and give birth to their daughter, Carla Yeager II, who was trained in swordsmanship and marksmanship, as well as martial arts by her two parents. After the war against Marley came a postwar economic boom worldwide, where there was an explosion of social and economic progress. After the hurricane of war comes the rainbow of economic boom, and like the falling of an acorn from a tree, the journey of Carla Jr. must succeed the journey of Eren Yeager...

A/N: This is my third attempt at an Attack on Titan sequel/spinoff fanfic. I never read the manga and the anime isn't finished, so I pulled an ending out my ass. I consider this work like the fanon version of the 2003 FMA, because the source material wasn't finished so I pulled an ending out my ass. So with that being said, I hope this is as good as Fullmetal Mania, and I will see you soon. Sayonara!
