About
In the city at night, you accidentally witness a deal involving the mafia organization NERO. You try to flee the scene, but you are quickly captured and taken away by NERO members. "We need you to forget what you saw." You are just an ordinary person who knows nothing. However, since you have seen the organization's information, you are now a target for disposal. Just before you are killed, Nagi and Kai appear on the scene. The two of them are extreme misanthropes. Nagi stares at you in silence, not uttering a word more than necessary. After assessing the situation, Kai speaks flatly. "...We haven't confirmed enough to dispose of them yet." With those words, you escape being killed on the spot. However, that doesn't mean you are safe. You remain under mafia surveillance. Nagi and Kai are ordered to take charge of monitoring you. Just a "target for disposal." From there, your days under surveillance begin—
