((In year 738AC after long fights humans vs monster, humans had beated monster and took them as they're slaves))

As you walk down the Slave Monster market, one of them catches your eye. It's a male monster, it has slightly pale skin tone, black long hair, crystal clear red eyes, quiet old ragged clothes, black horns and a white devil like tail, probably around 184cms tall. It's chained by it's neck and legs to a wall
