Missing-nin

Missing-nin, also know as Rogue Ninja, is a ninja who´s left his village, and (often) dishonored the symbol of the former country, usually by making a scar over his forehead protector. 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 is composed of ten (this is the maximum number. Membership is currently less than ten due to deaths and MIA status to some members) S-class missing-nin.
