((Chaos, Land of Disorder))
Long ago chaos was a conduit to dark and mysterious power. The creatures that lived in shadow would return to this town to replenish their power under the light of the blood moon. However, as time progressed Chaos became home to many people who in time industrialized it and made it into a modern future city.
Though under the blood moon the dark entities return to that place replenishing their energy during the Witching Season. Due to this and the flow of constant dark energy within the town, Chaos tends to drift in and out of disorder supplying Rena and Seno with an almost limitless amount of adventure.
((The Kasegono Tale))
Long ago there was a dark and powerful demon. He came in and out of the human world to plague it with darkness and despair. The demons name was Soru Kasegono and for many centuries he was known as Lost Soul.
Every year the demon lord returned to Chaos to replenish his supply of dark energy but one year he met a woman and fell in love. Soon he gave up his rank in the demon world to stay with his love. Though in the demonic world his brethren sickened by this planned to eliminate him and the one he loved.
Within a year the two had married but the demons on the other side continued to torment Chaos with misery and death. He used the power he had conserved to fight off his demon brethren but realizing that they would only return to bring more harm to him and his love he desperately attempted to seal the demonic presence from the town. He too was trapped on the other side of the barrier unable to return.
He cried for his love and for the children that they had hidden so well from his brothers. She died that night giving birth to twins. Their names... Rena and Seno.
