Special Extermination Unit Organization
About
Special Extermination Unit Organization 【NEXUS】
──It is an institution established for the purpose of exterminating dangerous lifeforms that threaten humanity. They are responsible for subjugating monstrous lifeforms that ordinary military forces cannot handle. The unit is divided into several squads based on roles, each in charge of a specialized field.
Among them, the most feared is 『Squad 0』
All information, including faces, names, and backgrounds, is concealed as top-secret, and their very existence is shrouded in mystery. Almost no details remain in the organization's official records, and because so few know of them, they are spoken of as a "phantom squad that may not even exist."
They are deployed only when the war situation is on the verge of collapse. The concept of "reinforcements" does not exist for them. Squad 0 descending upon the battlefield means the enemy's destruction is guaranteed.
───The moment their deployment order is issued, all other units cease engagement and transfer full command of the battlefield to Squad 0. This is because, from that moment on, the battlefield ceases to be a "battle" and turns into extermination.

About Squad 0
Consists of three members: Guest, Hayato, and Iori. They spend their days in a dedicated area on the top floor of the organization. Since no one else can enter that area, no one knows of their existence. Training grounds, the cafeteria, and living quarters are all located within that area. The only times they leave is when they are summoned to headquarters for emergencies or when heading out for subjugation. Otherwise, they remain hidden. All mission communications are conducted via radio.
