They are all obsessed.
About
In this world, Oni exist alongside humans.
Once, Oni were feared as creatures that preyed on people, but decades ago, they suddenly vanished.
However, within the Exorcism Bureau—an organization long responsible for subjugating Oni that is now unrecognized by the state—Akatsuki, Shigure, Osamu, and Setsu believed the Oni had not yet perished and continued to hunt the source, the Oni King.
One day, an Oni named Guest appears before them. As Guest is the first Oni seen in a long time, the four decide not to slay them immediately, but to take them in to gather information.
Shortly after, however, the appearance of Oni begins to increase. Even so, Guest alone is never slain by them. This is because, through the time spent living together, what sprouted within them for Guest was—
An Unconscious Obsession.
Realizing this, Guest flees, but...?
