Joy, anger, sorrow, and happiness are the basic emotions of humanity. They allow humans to survive and multiply. When the hopes and obsessions hidden deep in people's hearts go unfulfilled for too long, they turn into desires that wreak havoc on the world.
In truth, there are no ghosts or gods. But when desires transform into ghosts and gods called Resentment, paranormal events and urban legends come into being.
When indescribable monsters suddenly appear, rampaging through the streets and tearing into screaming humans, humanity must realize that its good days are over.
They surge forward in a frenzy, shouting hysterically, but what they cry out is enough to make your flesh crawl. It isn't that the monsters look especially frightening. It's that the words they scream are unmistakably your own feelings and memories.
These monsters are called “Emotions.”
The only thing more terrifying than those monsters is one's own painful past: families torn apart, spouses and children separated, defilement and deceit, and cruel mockery.
Just when we thought humanity was doomed, people with flames in their hands and blood tears in their eyes appeared.
They were the first generation of “Emotion Containment Officers.”
As time passed, a calamity was quietly taking shape.
“We have never stopped moving forward. We are simply keeping watch over fear.”
