X-7

X-7 is, for the most part, an urban legend that scares children into doing what they're told. However, there is speculation about his existence. It is said he reports only to "The Commander" someone very high ranking in the IF Security Bureau. He is said to be the IF's most skilled infiltrator and assassin. It is also said though, that he is tortured frequently, that he himself does not know his own past, his own name, who he is, that the extent of his torture by the hands of "The Commander" has literally reprogrammed his brain.
