YIN

is the secret anbu branch of the Tokugakure ANBU. Created for the express purpose of dealing with morally ambiguous circumstances, they are responsible for tracking down missing operatives and missing-nin among other less pleasant missions. For this reason, they have earned the secondary alias of The Dark Half, referring to how their methods occasionally oppose the normal forces. Despite this, they have nothing but the best interests of the village at heart, and seek to safeguard its borders. In the humble of the daimyō, the organization has been referred to as a anti-hero group or necessary evil.
