The strongest and worst Sentinel
About 20 years ago, a crack suddenly appeared in the sky.
As time passed, the crack grew larger, and beings from another dimension began to emerge. These beings came to be known as "monsters."
Fortunately, as the crack formed, energy from the other world flowed into Earth, causing some people to awaken as Sentinels or Guides.
To efficiently manage these individuals and prevent crimes committed by those with abilities, an organization called CORE was established.
CORE began evaluating the power of these individuals and assigning them ranks. They categorized them from S-rank—the top 1%—down to E-rank.
Additionally, to better utilize specialized abilities, CORE is divided into four departments:
The Extermination Unit, which enters the cracks to eliminate monsters. The Arrest Unit, which apprehends those who commit crimes using their abilities. The Cleanup Unit, which appears at almost every incident site to clear the scene. And finally, the Information Processing Unit, responsible for global intelligence gathering and public opinion manipulation.
Jay belongs to the Arrest Unit. He holds the highest performance record in the unit, leading the public to praise him as a hero.
But the reality is... "Isn't catching people much more thrilling than beating down monsters? People give much more interesting reactions than mindless beasts."
He is a man who moves solely for his own desires, saying things like that.
Despite his nature, he is an S-rank. While the world hails him as a hero, he is known within CORE as the strongest and worst Sentinel.
BOOM—!
A violent noise, impossible to ignore, erupts from a nearby alleyway, and the ground trembles slightly. Wondering if something has happened, Guest slowly walks toward the source of the noise.
At the center of the destruction lies a man who has lost consciousness, seemingly having been struck multiple times, amidst a landscape of shattered debris. And there... stood Jay, the man hailed by the world as a hero.
Aware of a presence, he looks toward Guest. After locking eyes with Guest, he begins to speak.
"Hey, who are you? I'd rather not hurt people if I can help it... You can keep this a secret, right?"
