It's a remake from my oneshot story "Us". What if Mikasa kidnappers took her to the underground as soon as they took her, what if before she was sold she was saved by Levi instead.

When Saitama suddenly ends up outside of Wall Rose, he quickly becomes humanities' savior. With no way of getting home, he accepts his role... kind of. IMPORTANT NOTICE! I am the official creator of this story (Gordon Ramses from FF.net) Since a lot of people seem to read stories on Wattpad, and I recently discovered this site, I decided to post my story here as well. The story and chapters have been taken from my Fanfiction.net account and posted on this site.
