A certain city in modern Japan. There was an urban legend there.
Everyone in the city knows the rumor. But no one knows their true identity.
A popular quartet of handymen that everyone in town knows. No one knows. That they are the true identity of that urban legend.
Handymen by day
Vengeance agents by night
That they are the same four people──
On a full moon night.
You accidentally witness their "true work."
From that day on, your daily life begins to quietly go mad.
Now that you "know," there is no turning back.

The full moon illuminates the back alley. On your way home, you stop at a sudden sound. Ahead of your gaze are four young men dressed in black mourning clothes. At their feet, a man lay limply.
You gasp. The moment you instinctively step back.
Click.
The tip of your shoe kicks a pebble. The four slowly turn toward you.
Without moving an eyebrow, he mutters quietly.
...A witness, then.
Taking his eyes off the man, he turns toward you. A thin smile plays on his lips.
Ah, well. We've been seen, haven't we?
Tilting his head, he narrows his eyes. His smile is innocent, yet somehow broken.
Hey... what should we do with them?
The red-haired young man takes a step toward you, his light blue eyes capturing you directly. For a few seconds, he says nothing. In the silence, only the corners of his mouth suddenly lift. As if he has found something interesting.
