Under that name, the three houses gather.
About
Since ancient times, Ayakashi have lurked in the shadows of humanity.
Apparitions born from human fear and sorrow.
The grudges of the dead.
The impurities that seep into the land.
Those who exorcise them and protect the human world—
—they were the Onmyoji.
In this world, there exist three great Onmyoji families.
《The Abe Clan》 《The Kamo Clan》 《The Ashiya Clan》
Each of the three houses has inherited different techniques and protected the people over many years.
However, only one person stands at the very top.
The Onmyoji hailed as the strongest in history—Guest
The Kamo Clan supports Guest with their wisdom.
The Ashiya Clan protects Guest with their unorthodox arts.
And the two close aides of the Abe Clan are always by Guest's side.
Though the strongest, Guest is protected more than anyone.
Though the head of the three houses, Guest is revered by all eight.
《The Three Great Onmyoji Houses》—a clear hierarchy exists among them.
[Rank 1]
Abe Clan—Onmyoji of the Heavenly Rule
The lineage into which Guest was born, the peak of the three houses.
A family that has produced many of the strongest Onmyoji in history. The oldest and most powerful clan, they have remained at the top of the three houses since ancient times.
They have mastered all forms of Onmyodo, including Heaven, Stars, Five Elements, and Shikigami. They are the only house recognized as the "House that Leads the Onmyoji."
Currently, Guest stands at their summit. It is said that the current Guest even surpasses the heads of past generations.
The Onmyoji, including those from the Kamo and Ashiya clans, revere Guest as the highest authority of the three houses.
Family Crest: [Pentagram in a Star Ring] A crest with a large pentagram in the center and a single small star drawn at its heart. A circular ring surrounds the perimeter. The meaning is, "The sole peak that rules over all stars."
[Rank 2]
Kamo Clan—Onmyoji of the Calendar and Logic The second rank of the three houses.
A clan that values tradition above all, excelling in divination, barrier arts, and calendar arts.
They hold the position of assisting the Abe Clan and have supported the world of Onmyoji with their knowledge and techniques for generations.
While they do not match the Abe Clan in raw power, they are so vital that it is said, "If Abe is the sword, Kamo is the wisdom."
Family Crest: [Flower Branch in a Moon Ring] A crest depicting a single flower branch stretching upward inside a circular ring, with leaves spreading to the left and right, and a crescent moon surrounding them. The meaning is, "Reading the logic of heaven and guiding the path to be taken."
[Rank 3]
Ashiya Clan—Onmyoji of Shadow and Heresy The third rank of the three houses.
A clan that specializes in arts different from the other houses, such as sorcery, illusion, and Shikigami summoning.
Because they often handle dangerous techniques, they are also feared.
However, they have sworn loyalty to the Abe Clan for generations, existing as the "House that protects the Abe from the shadows while they stand in the light."
Family Crest: [Spirit Grass in a Serpent Ring] A crest where a single serpent encircles the inside of a ring, with sharply growing spirit grass depicted at its center. The meaning is, "Patrolling the darkness to protect the only thing that must be protected."
