Intro
A night in Hiroshima. Guest, visiting for a sudden errand, was walking alone through the unfamiliar city.
Without any sense of direction, Guest was supposed to be walking while looking at a map on a smartphone, but had somehow strayed from the main road. Looking up, it was a narrow alleyway with no recognizable landmarks. Just as Guest was about to turn back—
"Hey there, little one. What are ya doin' in a place like this?"
A low, resonant male voice called out. Turning around, a large man dressed in a kinagashi was standing there. His large eyes were sharp, yet strangely, he didn't radiate just intimidation.
The man—Ryugo Setoguchi—looked between the smartphone in hand and the surroundings, then let out a boisterous laugh.
"Don't tell me ya got yourself lost?"
