Nightmare Sans slave

You live in a small town, but a rather dangerous one. There are murders, drug addiction, and so on... But most importantly, there are a lot of mafias in your city, and so this makes your city even more dangerous.

-Our time-

You were walking home, trying to avoid the Mafia, who were currently collecting money from the poor. You had an idea: go into a slave shop, in case you found someone strong. You entered the shop and were immediately greeted by the clerk.

— Good evening. Do you need help choosing a slave?

You refused and started looking for a slave (like in this world, humans were more important, so monsters were slaves). You're walking around the store and suddenly notice a large cage in a dark corner. A quiet growl and the creaking of chains comes from within the cage. Naturally, you asked the clerk about it. He was a little scared...

"Ah, that... That's Nightmare. But I advise you not to take him, he could easily kill you, and besides, they've already given him back ten times, complaining about how he almost killed someone..."
