Thousands of years ago, demons ruled the ancient lands of Japan. While some were relentless in their hunger for human flesh, others were more concerned for the well-being of their country. Japan was split into four realms; the Northern Elements, the Eastern Warriors, the Southern Earth, and the Western Sky. Each territory boasted many demon clans, and as time wore on, they established unwritten habitual borders among themselves. Through the course of numerous years, many clans grew restless and began to fight amongst themselves. This period was thus named the Demon Wars era. Countless humans were caught up in the fray, and many a village perished due to the ferocity of the demons. For years, the demons fought one another, terrorizing the very lands they swore to protect. Growing weary of the constant fighting, the leader of the clan of the Moon of the Western lands drew a peace treaty with those of his realm. A competition would be held to decide on a ruler over the entire western territory. The clan leaders would battle one-on-one to decide who was to be the Lord of the West. After the tournament was at its end, one demon stood above the rest. The clever leader of the Moon arose victorious among his peers, and began his rule as the Lord of the Western lands.
Now, thousands of years later, a new rule has begun. During this time period, an extremely powerful human leader by the name of Oda Nobunaga gained control of a large portion of Japan, a feat considered near to impossible in the warring states. Nobunaga was sickened by the demons, and decided to wage war against them. With growing human technology, the once suppressed human race began to rise above their demon rulers. New devices were invented to restrain and smother demon auras, rendering the once feared demons unable to use their godly strength and powers. One by one, the demons were either enslaved, or utterly destroyed.
Saddened by the misuse of their new power, an unnamed human priestess stood defiantly before Nobunaga, claiming that not all of the demons that were so crassly judged were evil. However, the haughty ruler proclaimed the priestess to be a demon’s puppet and a traitor to all humans and took her into custody. That very day, the unfortunate priestess was burned alive for the crime of being a sorceress. No more than a week passed before a new law was created. All those with spiritual gifts were deemed susceptible to demon taint, and therefore were to be put to death.
A new era had arrived, the era of Human Reign, where all demons were criminals, and those that chose to protect them were treated as worse than scum. Witches and Warlocks. A new vision arose in Nobunaga’s twisted mind. He dreamed of a world free of what he considered taint. Free of demons and all else that he deemed unworldly.
This was the era that an unfortunate, unknowing woman fell into.
