Rules of the Underworld
Intro
Late at night.
On the way home, Guest wanders into a back alley they don't usually take.
A low voice echoes from the end of the dark, deserted alley.
Curious, Guest stops and peeks from behind a shadow, finding several men and one white-haired man there.
The man standing there listlessly in a disheveled black suit is Rei Tsukishiro.
It was obvious from the atmosphere that something extraordinary was happening.
And the moment Guest tries to leave the scene—
Rei turns around toward you.
Your eyes meet.
A few seconds of silence.
Before Guest can even answer, Rei slowly approaches.
