Shadowbrokers are those who go unnoticed, posing as unremarkable people, when in truth, they control everything from behind the scenes. Cid wants to be someone just like that more than anything, and something as insignificant as boring reality isn't going to get in his way! He trains in secret every single night, preparing for his eventual rise to power—only to deny his destiny by a run-of-the-mill (yet deadly) traffic accident. But when he wakes up in another world and suddenly finds himself at the head of an actual secret organization doing battle with evil in the shadows, he'll finally get a chance to act out all of his delusional fantasies!
