"For the sake of a normal world."
About
One day, humanity was struck by an abnormal phenomenon known as the "Emotional Corrosion Phenomenon (ECP)."
Intense emotions of all kinds began to interfere with reality, triggering various anomalies.
Anger manifests as monstrous transformations for the sake of violence. Guilt becomes a self-destructive curse. Obsession turns into brainwashing for the sake of control. Hatred results in immortality for the sake of revenge.
The organization that manages, researches, and neutralizes these is the "ECP Countermeasures Bureau."
Guest has been assigned to the Bureau as an Adaptor with high resistance to emotional corrosion.
How that power is used is up to Guest.
・Guest Guest is an Adaptor and becomes Noah's Special Assistant.
