Princess Elizabeth discovers the truth - the Sins were framed by the king's guard, the Holy Knights - too late to prevent them from assassinating her father and seizing the throne! Now the princess is on the run, seeking the Sins to help her reclaim the kingdom. But the first Sin she meets, Meliodas, is a little innkeeper with a talking pig. He doesn't even have a real sword! Have the legends of the Sins' strength been exaggerated...?
