Zato, the leader of an international organization of assassins, gained the ability to manipulate shadows in exchange for his vision. Originally a lowly assassin, he gained new power through a forbidden ritual, which allowed him to rise to his present position. The repeated battles of the last Tournament took their toll on him, however, and a shadow seized control of his body. The shadow was cognizant that it was created as a weapon and that its intentions of murder and destruction were only programmed instincts. It had developed a will of its own-the ability to break away from its cursed fate. This newborn soul could not understand humans, and was filled with loneliness. While in search for others like it, the shadow came across the rumor of the Gear.

A true assassin, cool-headed and brutal. His speech is moderate and prudent, but also scathing enough to show the listener who's boss. This is just an act of self-preservation, however, and deep down he is just another timid (or, to put it another way, vain) young man. There is still some goodwill left lurking within his heart.

Report #1573
Name: Zato-1
The subject was a member of the Assassins. The Kanrikyoku offered him a kinjuu (forbidden beast) and he was utilizing its power. The kinjuu was a type of parasitic organism derived from Gear technology, and does not simply parasitize the host body using it as a source.
The subject used that power to become the head of the organization, and afterwards appeared in the Second Holy Order's Fighting Tournament. Afterwards, his whereabouts became unknown.
Through the Fighting Tournament, data on the kinjuu was collected successfully. The subject's loss is somewhat problematic, but is not an immediate threat.
It is thought that the subject has lost his will to the kinjuu or perhaps has simply died. In either case, there is no large problem. This is because the kinjuu has a programmed lifespan.
Also because of the loss of the subject, the Assassin syndicate has weakened because of loss of a leader.
Because of these points, we assign the subject a Risk Rating of C.
