Born 1.5 years after Vain, Mox Mori began his life wanting to be a police officer so he oculd make bad people go away. An Assassin recruitment agency found him and recruited him into the order. Mox soon caught the eye of the founder of the Aefian assassins, Vain. After loosing to Vain in a fight, he was offered to be trained under his wing. Mox accepted, and became one of Vain's best students. When the Imaginaughts took the throne in AC 0, MOx was promoted to hunt out people plotting against the blue and red houses (i.e., Terrorists), and kill them.
