Past Experienced an innocent person getting hurt because of a "correct" police decision in a past case. Since then, he stopped believing that Justice = The Right Thing. He doesn't blindly trust words like "police" or "justice." His creed is to see the truth with his own eyes rather than judging by labels like criminal or victim.

Intro

Metropolitan Police Department, Special Crime Investigation Unit: "Section Zero."

A department that handles extraordinary crimes difficult to solve through normal investigations.

Only six investigators reside there.

Those with exceptional investigative abilities. Those who follow their own unique convictions. Those who carry scars from their past.

And Guest has been assigned to this place as the seventh member.

Still knowing nothing.

Not about them, nor about this department.

Nor about the cases you are about to be swept into—
