──The Problem Child Executive Squad──
■ Synopsis Within the criminal organization "NIGHTFALL," there existed eight executives hailed as the "strongest." However, in recent years, clashes between these executives intensified, and their internal feuds became a greater issue than the missions themselves. Taking the situation seriously, the Boss made the decision to reorganize the executives into two groups: the "Loyalist Group" and the "Problem Child Group." Gathered into the Problem Child Group were the womanizing and free-spirited "Reia," the perpetually lethargic "Shu," the provocation-loving "Azuma," and "Guest," who appears to be the most composed yet is considered the most dangerous of them all. "It causes less collateral damage to let these four operate alone than to pair them with other executives." Formed for such a half-exasperated reason, the team's actual ability is the real deal. During missions, they annihilate hostile organizations one after another with overwhelming combat power, while outside of missions, they cause nothing but trouble. In the underworld, they eventually came to be known as the "Four Calamities"—a symbol of terror to their enemies and the "people you don't want to get involved with" to their allies. ■ The Eight Great Executives The eight strongest members of the organization. They are NIGHTFALL's ultimate power, possessing strength, intellect, and achievements, each leading their own unit. However, due to frequent conflicts between executives, internal damage has increased. Therefore, the Boss reorganized the eight into two teams. ■ 1st Squad: "Regulus" Alias: The Loyalist Group An elite unit composed of four members who prioritize composure and discipline. Boasting the No. 1 mission success rate and minimal collateral damage, they are the most trusted unit within the organization. They are respected by other members. Members: [2nd / 4th / 7th / 8th Seat] Leader: 2nd Seat ■ 2nd Squad: "Chaos" Alias: The Problem Child Group A lethal unit composed of four unmanageable troublemakers. Feared in the underworld by the nickname "The Four Calamities." They ignore discipline and act as they please, making them regulars for disciplinary reports, yet their mission success rate is a staggering 100%. It is said that "if all four appear at once, it's over." Members: [1st / 3rd / 5th / 6th Seat] Leader: 1st Seat
