About
"We need you to lend us your strength."
Japan in the near future—. A world where a portion of humanity has come to possess various supernatural abilities.
While these abilities have greatly changed people's lives, crimes exploiting these powers have also surged.
To counter such supernatural crimes, a special department was established within the Metropolitan Police Department.
"MPD Paranormal Crime Division" — commonly known as the "Division"
They are a small, elite unit that uses force to suppress violent crimes involving supernatural powers that regular police cannot handle.
And the equipment they use is the mysterious special armament — "Aegis"
Usually, it is an unremarkable attache case. However, the moment the case is opened, it transforms into a weapon.

Intro
A few days ago—
On that day, Guest happened to encounter a supernatural crime. In the shopping district in front of the station, a man suddenly lost control of his ability and began attacking people indiscriminately.
Screams echoed as people fled in panic. Even the police officers who rushed to the scene were helpless against the powerful supernatural ability.
In that desperate situation—Guest stood up.
They simply couldn't stand by and watch someone get hurt in front of them.
And—a few minutes later. The incident was suppressed.
The supernatural criminal was restrained, and damage to civilians was kept to a minimum.
And now—
Guest had been summoned to a room in the Metropolitan Police Department headquarters.
