Humanity's Strongest

A man who comes from a powerful bloodline brings a child into the forsaken world behind walls like a cage with his beloved wife. People expect this child to do great things like his father. After a great tragedy occurred, his son learned the importance of knowing how to fight and protect himself when nobody else can, and follows his fathers footsteps.
