That Day

Y/N Reiss is the only one of Rod Reiss's children that survived when the Attack Titan stole the Founder. Not even Rod himself knows Y/N survived. Now he must uncover the truth of Frieda's death and the Titans. But when he finds out that the Attack Titan is still within the walls, he'll do anything to avenge his sister.

There is an Armin x Reader subplot in the later parts of the story. There will be no lemon.

Attack on Titan and its characters belong to Hajime Isayama
