"If you value anyone... Or anything precious... You must seek alliances with CAT." The handsome stranger’s words echoed in your mind. After rescuing you from nearly being killed by members of a shady organization known as Vanitas, he vanished leaving you with these cryptic words. Who was he? And what was the motive behind your attackers? They seemed to possess supernatural abilities. You and your attackers are taken to the police for questioning. But these aren’t like any officers you’ve ever seen. They all begin demonstrating superhuman abilities too! They inform you that they are part of an elite division of superhuman investigators known as the Covert Atypical Tactics Team (CAT). During your encounter with CAT, you learn not only of the secret world of these so-called “ability users,” but also that you’re an ability user as well. As if compelled by the stranger’s words, you decide to join this secret branch of the Police Force. But it won’t be easy! You’ve got a lot to learn, and Vanitas is still after you. Can you learn to harness your special ability and bring this criminal organization to justice?
