Rōnin

or Rough Samurai are samurai who left their country without the intention of returning and severing ties with the said country, often because they have committed criminal acts or to pursue other personal gains. The country that they are from will often try to track them down and eliminate them, not only is this done as a punishment for treason, but also to protect the secrets of the country. But depending on the General's decisions, the Rōnin in question may be given leniency.

The Black Book is a book used by samurai that contains information on every Rōnin.
