The human race is at war with the Demon who lived in the shadows and underground and when they needed help more than ever, THEY started to come forward. Humans who had hidden in the shadows for hundreds of years people with the abilities to fight against demons. Some chose to share their knowledge to the rest of the world in hopes of winning the war, while others kept their abilities to themselves. Matt had lost everything in war, his home, his family, and the only thing he had inherited was a plastic cylinder that he couldn't even open. But when the cylinder had finally opened, Matt was granted a system and his whole life was turned around. Perhaps for good or maybe for bad. While he was happy that he finally have a power of his own, he received a notification message which he never think he could complete. < New Quest > < Your Hunger grows > < Go for a rampage and hunt down two humans >
