Humans were the cheapest and most popular slaves in the market. Nearly 100 years ago, there was the biggest war in the history of mankind, the Rage Of Hell. Demon lord Desmon was the one to initiate the war. His power was enough to make those around him shiver from fear. His aura was so menacing it made people faint when going near him. Desmon was the definition of the word, “Demon”. Once the war began, terror was brought to the green lands. Once luscious green fields were now red hellscape. Beastmen and many other races and kingdoms were quickly subdued. Elves, dwarfs, vampires, and many more followed not so long later. After a brutal and fearsome war, only humans were left standing on their two feet. They had the hero on their side! The brave and strong hero, Argera! He was the bright star of the humans. Their one and only hope of winning the gruesome war. He defeated dangerous demons with one swing of his holy sword and took down whole armies on his own. Argera even killed one of the 8 strongest Demon Shoguns, Martha. Desmon finally had enough and snapped. He went out on the harsh battlefield himself and defeated the all-mighty hero with ease in the Battle Of Towhog. This day marked the end of humanity’s independence. As a severe punishment for resisting, Desmon labeled humans as slaves to other races. Humans were already much weaker than others, so they were taken advantage of and exploited without any resistance. Though, everything was set to change, when a human named Nikari received a special blade after a traumatic experience. What\'s set for his future?
