It was a tough world. Kakashi had grown, cut his teeth on it and it’s great wars. He survived— not just because of his skill but his bonds. And there were so few of them left, now.
Kakashi is left alone in a cruel world with nothing but his late Sensei's newborn child to comfort him. What can he do, with everyone he had ever cared about dead?
Only time can tell.
