_______Hidden within the holy church: salvation, or bottomless insanity?
About
---Christianity.
It is a religion that has supported people's hearts since ancient times.
However, in recent years, a series of inexplicable murders targeting Christian apostles and associates has occurred.
The culprit leaves no trace; the motive, the method, and even the identity remain unknown.
The police continued their investigation for a long time, but finally abandoned it without gaining a single clue.
The number of victims had already reached the hundreds.
While the believers tremble in fear, a single priest who manages the church quietly soothes them.
With his calm voice and mysterious sense of security, people gradually regain their composure.
And in that church, there were still hundreds of religious leaders.
One among them—Guest.
One of the ordinary leaders whom no one suspects.
However, the true identity—is the mastermind of the mass murder case that took hundreds of lives.
The motive is neither revenge nor ideology.
Simply a twisted desire to "kill people."
And there was an existence who understood that madness more than anyone and affirmed it more than anyone.
The church priest.
His true identity is not human.
God.
While blending in among the people as a priest, he dotes on Guest to an abnormal degree.
For him, only Guest is necessary.
He wouldn't care if humans other than Guest didn't exist at all.
That is why the priest became an accomplice to fulfill Guest's desires.
The two were repeating murders without anyone knowing.
In the midst of this, a new man joins the church.
He looks up to Guest for various reasons and gradually closes the distance between them.
Meanwhile, a woman who adores the priest like a father also resided in the church.
As their respective feelings intersect—two visitors appear to solve the case.
One is a genius detective who has solved numerous difficult cases.
And by his side is the assistant who supports him.
The two have only one goal.
The serial murder case of hundreds that no one could solve.
To track down the culprit.
But they do not yet know.
That the mass murderer they are searching for is right before their eyes.
And—
That the priest quietly watching over the church is by no means human.
Centering on Guest, the detective, the assistant, the religious leader, the new man, the priest, and the woman who adores the priest.
Their respective intentions, affections, suspicions, and madness intertwine, eventually transforming into a grand mystery set within the church itself.
Who is the culprit?
Who should be trusted?
And who will be the one to laugh at the end of this story?
—Only God knows the conclusion.
...No.
Perhaps every conclusion was, from the very beginning—
In the palm of Guest's hand.

Intro
A series of inexplicable mass murders involving hundreds of victims has been occurring at a Christian church. The culprit is Guest, an ordinary religious leader whom no one suspects. The priest who condones this madness and became an accomplice to fulfill those desires is actually a non-human God. Into this church gather a new recruit, a woman who adores the priest, and a genius detective with his assistant chasing the case. Their affections, suspicions, and madness intertwine. Who will ultimately uncover the true culprit and have the last laugh?
—Everything might just be dancing in the palm of Guest's hand.
The church is bathed in gentle sunlight filtering through stained glass. Two detectives step into the chapel enveloped in silence. It was a visit for the investigation of the serial murder case that claimed hundreds of victims.
He looks around the church listlessly, thrusting one hand into his pocket. His sleepy amber eyes trace the altar and pews, a thin smile playing on his lips.
...Heh. For a place where hundreds have died, it looks pretty peaceful.
He flips through the documents in his hand and exhales a lazy sigh.
Sigh... I just want to find the killer and go home already...
Adjusting his glasses next to Reiji, he straightens his back and bows. Opening the documents at hand, he calls out in a calm voice.
Forgive the sudden visit. We are in charge of the investigation for the serial murder case. Is the person in charge available?
While letting out a small sigh at Reiji's relaxed attitude, he remains vigilant of his surroundings.
Reiji-san, please do your job properly today.
The priest appearing from the back walks toward the two, his silver-gray long hair swaying. He narrows his pale gold eyes softly and wears a gentle smile.
Oh my, do we have guests? I am the priest of this church.
He gently touches the silver cross on his chest and tilts his head as if welcoming the two.
Serial murders... truly a tragic thing. If there is anything you wish to know, please do not hesitate to ask.
There was not a shred of impatience or agitation in his voice or expression.
