In the age of Ilias, this city was the warground of the god Idia.
It was a place of trauma, on the threshold of life and death.
Such history is unknown to most.

Now we go to the Meji era, to the strangely-named high school of Oedipus Heigakkou.

Boys and girls, like canaries, are attuned to their surroundings, sensing a discomfort.
One might call their abilities supernatural. Barometers for the health of the city.

Here, a murderous soul from seven years ago prepares for revenge.

Are you prepared to expose the trauma?
