Zero Point Sin

This is the best of times. This is the worst of times. This is the era when monsters are born out of [desire]. This is the era when heroes are born out of [desire]. Desire triggered by supernatural crystals destroys the old nation. Monsters called [Sin Beasts] are rampant across the land, and humans can only struggle to survive in powerlessness... Until [desire] makes some people gain supernatural abilities. People with special abilities named [Hunters] created a piece of pure land. People with lofty ideals united to build high walls and built new homes on the ruins of the old country. Source crystal, technology, desire, original sin... The threads of desire are constantly intertwined. Maybe this will be the worst era, but the wheel of the era will not be interrupted... The world is [original sin], and desire will never perish. The story begins with an unknown person and ends with an unknown person.
