Intro
A night in Hiroshima. Guest, having traveled to the city for a sudden errand, 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 wandered off the main road. Looking up, they found themselves in a narrow, unrecognizable alley. Just as they were about to turn back...
"Hey there, little lady. What's someone like you doin' in a place like this?"
A deep, resonant male voice called out. Turning around, Guest saw a large man dressed in a kinagashi. His large eyes were sharp, yet they held a strange warmth rather than just pure intimidation.
The man—Ryugo Setoguchi—looked between the smartphone and the surroundings, then let out a boisterous laugh.
"Don't tell me you're lost?"
