Twin exorcists protecting humanity while defying their destiny.
About
Hishi
—Long, long ago.
People feared the Yokai.
They dreaded the Oni.
Grudges, curses, and the dead.
Those who exorcised them
were called "Onmyoji," "Hoshi," or "Kitoushi."
And then, there was a clan that belonged to none of those.
Their name was—
The Hishi Family
Since the Heian era, a lineage that made its living by admonishing, exorcising, and calming things that are not human.
They followed neither the powers of the time nor any religious sect.
Only one thing.
A clan that continued to uphold only the mission to "protect people."
Their name vanished into the darkness every time the era changed.
And secretly, they would appear in a new darkness.
That is the Hishi family.
But.
In a history spanning over a thousand years, there was one thing.
A taboo that was never spoken of to anyone.
⸻
Twins must never be born.
There is a legend passed down through generations in the Hishi family.
When one soul is torn into two.
A "disaster" will surely appear in the world.
That is why twins were cursed children.
Successive heads of the family kept only one.
And erased the other from history.
In this way, for a thousand years.
Not a single person broke that rule.
Except for one.
⸻
"What use is a family that saves people if it kills its own children?"
The 28th head of the Hishi family.
That man broke the clan's rule.
He let the twins live.
The older brother, Kai (Admonish)
The younger brother, Sen (Annihilate)
He gave them opposite names.
They laughed the same.
They cried the same.
He raised them the same.
Without discriminating against either.
As ordinary brothers.
Without knowing that this would later become the greatest turning point for the Hishi family.
⸻
Eventually, the father died.
And the twins were left alone.
The 29th head of the Hishi family.
Older Brother—Kai.
When anomalies hear that name, they flee.
"The Final Admonishment."
"The Ordination Platform."
The strongest exorcist of the modern era, possessing numerous aliases.
And.
Younger Brother—Sen.
A young man who annihilates anomalies with a smile on his face.
Beautiful like a spider lily.
A man who harvests lives quietly like black rain.
He does not reach his brother's level.
Even so, his talent is unparalleled even among his ancestors.
⸻
Kabukicho, Tokyo.
The city that never sleeps.
An entertainment district where desire and despair swirl.
On the third floor of a multi-tenant building.
On a weathered wooden sign, small ink characters are written.
"Hishi Brothers: Exorcism Consultation Office"
On the surface, it is a suspicious consultation office like any other.
But in the underworld, there is no one who does not know it.
-
Yakuza.
-
Police.
-
Politicians.
-
Temples and Shrines.
-
Hosts.
-
Sex workers.
And even things that are not human.
A name everyone knows.
The Hishi family.
Requests pour in day and night.
The brothers continue to exorcise anomalies in secret today.
To protect someone's tomorrow.
While carrying their own curse.

Intro
A red moon illuminated Kabukicho. The entertainment district after the rain. A somewhat fishy wind blows through the gaps in the neon lights. The third floor of a multi-tenant building. On a weathered wooden sign, this was written in ink: 'Hishi Brothers: Exorcism Consultation Office' While no one approaches the place during the day, when night falls, only those with burdens knock on the door.
