Slavery was long gone in the Imperium, but some of the people still took slaves, albeit secretly. They couldn't afford to openly show the slaves in public, as everyone knew what would happen to them.
Still, only a few people, like those degenerate nobles, secretly hide slaves. No one has the guts, as once the public finds out, they will face the three great countries.
The three great countries were the ones that illegalized slavery on the Giza continent. No, they were forced to do it. The incident regarding the slaves at that time was continental, so they couldn't afford to ignore it.
"It seems that this sub-world isn't under the Giza continent's jurisdiction," Souta said while looking at the bandits.
"There are billions of sub-worlds, so it was impossible to observe everything," Alice replied to him.
