Everyone's life was planned way ahead of their arrival. Life runs like a straight line. The end of life is planned and they are to go as planned. If one is planned and scheduled to die early, they have no choice but to die. That that ruin the plan and continues to live are called human ghost. Human ghosts can be people who were scheduled to die as a baby, but they are still living because they came for a reason and the reason must be figured out before leaving. A guardian named Tora looked after these human ghosts in a forest that is located in Sitano. The forest was forbidden to people to enter. This forest was called the Forbidden Woods. It is believed that trespassers would die automatically for stepping in.
Tora was the creator of four powerful exorcist families, a priest and priestess family, along with a demon slaying family to manage the numbers of human ghosts low. The four exorcist families are all specialized in something particular. The four families are the: Alma family, Kappa family, Yokoshima family, and the Obake-Mo family. The priest and priestess family is present to purify spirits and sending them to peace. The family was known as the Miko family. The demon slaying family is made to eliminate demon possessed spirits. This family was known as the Oni family.
The Alma has a specialty for the fastest elimination of metallic green eyed spirits. Metallic green eyed spirits were people who were killed naturally and they are still in the human world to say their last good-byes to their world. The exorcists of the Alma family practice archery for their exorcist role. They are the family of best aim in everything. People in the family have the highest pride and self-esteem composed to others. They are one of the strongest groups of exorcists.
The Kappa family is best known for the best decrease in rates of cerulean (metallic aqua) eyed spirits. Cerulean eyed spirits were people whose death is related to water and they harm others who did nothing to them. The practice for the Kappa family is swordplay for their roles as exorcists. The members of this family are very strategic and organized. They are the family with the best plans for anything to come. They are one of the intellectual groups of exorcists.
The Yokoshima family is known for their skills at handling metallic pink eyed spirits. Metallic pink eyed spirits were people whose death was caused by accident and they are roaming in the human world to say their last words and see their friends and family before they leave. The members of this family are very easy-going, friendly, and calm. The family is the best for a source of communication to others. The Yokoshima family is one of the musical groups of the exorcists.
The Obake-Mo family is known for their skillful catches of metallic yellow and purple eyed spirits. Metallic yellow eyed spirits were people who killed by planned actions and they are remaining in this world to avenge their deaths. Metallic purple eyed spirits were people who were killed by insanity, but are roaming around the human world to drive other people crazy. The members of this family are very secluded, excluded, and antisocial. The family is best known for their ceramic skills in building and making of puppets. The Obake-Mo family is rarely called for exorcisms. They are the artistic groups of people who provide entertainment.
When the four families are put together, chaos arises between the Alma and Kappa family. The Yokoshima family is the peace keeper to both families, while the Obake-Mo family is the peaceful people of the four exorcist families.
The Miko family is a family of hereditary priests and priestesses. They have the role to purify spirits to allow them to have a good and better afterlife. They have a sense of what might come in the future. The members of this house are very educated and linguistic.
The Oni family is a family of hereditary demon slayers. They are the best metallic red eyed spirit slayers. Metallic red eyed spirits were people who were possessed by a demon that causes harm to others and to themselves. The members of this house are quick and they are very energetically spirited. The family is one of the fastest thinkers of the intellectual group.
The six families made up half of Sitano's society. People of the city are very safe under the hands of the six families. Especially on the dangerous days of the year, the last day of October and the middle of July in the lunar calendar are dangerous. The six families are always prepared for those days since they are the days where spirits break loose and may cause trouble.
