The Black Mausoleum Incident──
A mysterious murder occurred at the abandoned Kuryokan Academy.
The murderer who calls himself the "Masked Death God" kidnapped eight victims, seven men and one woman, and asked the victims to "escape" from the abandoned school with many institutions. Those who did not follow the rules would be worse than those who escaped and would die.
A total of four people were killed in this incident, one was unconscious, and three suffered minor or serious injuries.
When the identity of the "Masked Death" was revealed, it caused even more uproar. No one expected that the murderer would actually mingle among the victims and take pleasure in observing the victims' reactions at close range.
I, Miyuki Hasakura, am the victim and survivor of this incident.
When the incident came to an end, the dead were dead, but the living were at a loss.
Because I know there are some parts of me that stayed in that night, in the abandoned school building in the Seven Mist Mountains
It feels like walking on a dangerous bridge that may break at any time. I wonder what is waiting on the other side of the dangerous bridge?
And I can only move forward cautiously and step by step.
