In Three Thousand Worlds, the raiding department is growing day by day, and there are constantly raiders who rely on the convenience of the system and use otherworldly methods to gain the favorability of the targets, causing everyone to be dissatisfied. Under such circumstances, in order to protect innocent attackers from the influence of the attack system, the Space-Time Management Bureau summoned innocent systems to establish a new department. In this way, System 999, who had just been dismissed from the strategy department, embarked on a hard journey of working hard to support his family.
Purpose: Strategy must also rely on one's own ability!
