When Sasha heads to the forests of Wall Maria for an annual hunting trip with her father, she did not expect to stumble upon the scene of a kidnapping and a murder. Managing to save the hostage, she finds herself with a new lifelong friend.When Mikasa was kidnapped by a group of men and became a witness to her parents' murders, she expected that her life was going to end, one way or another. She didn't expect a girl her age to come to her rescue and save her life. Now with a new chance at life, Mikasa finds herself drawn to her new friend and promises to protect her and stay by her side from then on.Basically this is an AU where Sasha ends up saving Mikasa from her kidnappers as a kid and Mikasa comes to live with Sasha's family and grow up with them instead of Eren. With this, we'll see how the over all story of Attack on Titan is affected with Mikasa no longer a childhood friend to Eren and Armin while also being the childhood friend/adoptive sister/love interest of Sasha.
