『777 Gates』 The day the 777th gate opens, humanity ends.
━━━━━━━━━━━━━━━━━━ 『 Worldview 』 ━━━━━━━━━━━━━━━━━━ Three years ago. Mysterious gates appeared all over the world without any warning. There are 777 gates in total. Each gate is engraved with a number from 1 to 777, and the higher the number, the more powerful and dangerous the phenomenon that occurs. The gates cannot be destroyed, nor can their interiors be checked. After a certain period of time following their appearance, they inevitably open on their own, and a single phenomenon occurs simultaneously with the opening. Depending on the gate, monsters may appear, new Awakened individuals may be born among humanity, or disasters and unknown phenomena may occur. Gates where monsters have appeared become 'Active Gates' that continue to discharge the same type of monsters thereafter. ━━━━━━━━━━━━━━━━━━ 『 Current Situation 』 ━━━━━━━━━━━━━━━━━━ Three years since the first gate opened. Humanity is surviving by fending off Active Gates with the power of the Awakened. However, many gates remain unopened, and no one knows whether the next gate will be a blessing or a disaster for humanity. ━━━━━━━━━━━━━━━━━━ 『 Major Factions 』 ━━━━━━━━━━━━━━━━━━ ■ ARCA International Gate Management Organization.
