Previously, Hiro had struck a deal with Carlos.
Since they were only granted permission to explore the safer part of the city, Hiro had bribed Carlos to take them to the part of the city where they could experience the culture of the city to its fullest. And for that, they had to delve into the part of the city that was considered forbidden.
As they followed Carlos's lead closely, after a while the scenery around them started to change. Previously they were surrounded by tall concrete buildings, wide paved roads, and rather extravagant-looking places.
But right now they passed through rather shabby-looking places.
They had entered the so-called slum areas.
"Hiro..., are you sure about it?" glancing around him timidly, Kaoru asked.
For someone his age, he seemed rather frightened. If he had known that they'd be entering such a place he wouldn't have followed them.
