The Protector's Protector

When Mikasa was a little girl, she watched as her parents were murdered in front of her, and was abducted. A few hours later, a strange boy and her best friend rescue her. She promises to herself that she will always protect them. And she does. But what if one of the people she protects was born to protect her from the shadows?

I do not own Attack on Titan, any of the characters, or anything else related to the anime or manga. I also do not own any of the pictures that are used, I find all of them on google. All I own is the OC and the laptop this was written on.
