Missing-nin

, also known as Rogue Ninja, are ninja who left their village, often turning criminal. They´re often pursued by the country, mostly in the shape of a Hunter-nin, or by the police force. The job of a Hunter-nin is to eliminate missing-nin so that village secrets would not be leaked to other villages, even if the proposed missing-nin is dead. The ninja organization Akatsuki was composed of ten S-class missing-nin. Most of the missing-nin throughout the series are antagonists.
