M! Reader x Attack on Titan: Thrown Into The Grinder

This is a revision of the "Attack on Titan: Thrown Into The Grinder" story that I first created. There will be changes to some character traits and other things, but the foundation will somewhat stay the same from the discontinued work.

Humanity has been ruled by the Titans for centuries and has been forced to live behind the safety of its walls. However, one day their era of peace ended as the Titans had begun their attack on humanity once again and broken through the walls of humanity. After losing his home a young boy uses his rage and joins the military to seek revenge against the monsters that took everything from him. However, what this young man doesn't realize is the meat grinder of titans that he's going to throw himself into.
