One writes the law, one enforces the will. Two justices tear the world asunder.
About
Apparitions are born from human hatred, sadness, regret, and desire.
Since ancient times, humans have lived while exorcising, sealing, or restraining them.
Two prestigious families have stood at the front lines of this battle.
One is the clan that "admonishes" apparitions—the Achira family.
The other is the clan that "exorcises" apparitions—the Ehato family.
Both are the strongest jujutsu lineages with hundreds of years of history.
However, their philosophies never intersect.
The Achira family says:
"Even an apparition has a meaning for its existence."
The Ehato family says:
"To save the lives that can be saved, we do not hesitate to discard a single life."
Those who value emotion, and
Those who value reason.
A conflict spanning hundreds of years has yet to reach its end.
⸻
The Ehato Family
A clan that has mastered sorcery, barriers, and sealing arts.
Their inherited technique—"Calligraphy Realm Arts."
A single character drawn with a brush becomes the law of this world.
"Bind" restrains the enemy,
"Seal" imprisons the apparition,
"Sever" cuts through even cursed karmic ties.
The character becomes the technique,
And the technique rewrites reality.
That is the divine secret art permitted only to the Ehato family.
⸻
Current Head—Oboro Ehato.
People call him "Mumyo."
A man who has cast aside emotion and weighs lives by reason alone.
The lives he saves and the lives he discards hold no difference in his eyes.
All he possesses is the mission to protect the world as a whole.
Apparitions fear him:
"When weighed on the Scales, one can choose neither life nor death."
⸻
And the man standing beside him.
Younger Brother—Madara Ehato.
The strongest vanguard of the Ehato family, who laughs boisterously and fights more fiercely than anyone.
However, the restraints covering his mouth are by no means decorative.
Within him sleeps a cursed energy so vast that ordinary people could never control it.
There is only one person in this world with the right to release the seal.
His brother, Oboro.
The moment the restraints are removed,
"Jakotsu" transforms from an apparition's nightmare into "Kikoku."
⸻
The older brother writes the law.
The younger brother makes the law reality.
Two as one.
That is the Ehato brothers.
The moment the brother draws a massive character in the sky,
And the younger brother's "Fukuryu" pierces it,
The character ceases to be a concept and becomes absolute reality.
Ehato Family Secret Esoteric Art—
"Tenchi Ippitsu."
It is the very "Reason" that even apparitions cannot overturn.
⸻
But the day arrives when that absolute reason begins to waver.
Barriers collapse in various regions,
And sealed apparitions begin to appear one after another.
It is a disaster that a single prestigious family cannot stop alone.
Emotion?
Reason?
Should one save a single life?
Or many lives?
The battle that will determine the fate of the world was about to quietly begin.
