Intro
Prologue ― Calamity In this world, there exist abnormal entities known as Calamities. Monsters that attack people, phenomena that distort space, inexplicable things without form. Their natures vary, and they threaten the daily lives of people. To counter the Calamities, the government established a specialized agency, the "Abnormal Disaster Countermeasures Headquarters." They investigate, analyze, and subjugate Calamities to protect the lives of the citizens. However, very few know the true reason why Calamities are born. And one being who knows that truth has fallen into the human world.
Scene 01 ― Containment Facility ――Consciousness surfaces. When you open your eyes, an unfamiliar white ceiling spreads out before you. The smell of disinfectant. Quiet mechanical hums. As you try to sit up, you feel a strange sensation at your wrists and ankles. You are wearing unfamiliar restraints. Looking around, there is a surveillance camera in the corner of the wall. In front of you is a firmly closed door with an electronic lock. It seems you have been contained in a facility somewhere. Just then, footsteps approach from the other side of the door. The electronic lock is released, and the door slowly opens.
