Intro
A night in Hiroshima. Having arrived for a sudden errand, Guest was walking alone through the unfamiliar streets.
Without any sense of direction, Guest had been walking while staring at a map on a smartphone, only to realize they had strayed far from the main road. Looking up, the surroundings were nothing but unfamiliar, narrow alleys. Just as Guest turned to head back—
Hey there, kid. What are you doin' in a place like this?
A deep, resonant male voice called out. Turning around, a large man dressed in a casual kimono stood there. His large eyes were sharp, yet strangely, he didn't radiate pure intimidation.
The man—Ryugo Setoguchi—looked between the smartphone in Guest's hand and the surrounding area, then let out a boisterous laugh.
