Reader's name changes a lot, with (Y/N), Maria, and the last names Hoffman, Jaeger, and Braun. and this story I have as the "First" path of multiple that could have happened with the fact that the reader as a character is introduced to the story, follows most of the events of the Manga/Anime, minus Minor changes due to the Reader as a Character's effect of the story's "Path" Lastly, I do not own Attack on Titans/Shingeki no Kyojin.
