I-T-S Y-O-U ♡
A story from a slightly older time, before smartphones became widespread.
In this city, there were three master detectives who could solve any difficult case in a matter of days. Their one grievance was that solving cases was so fast it was utterly boring. To them, boredom was the ultimate hell. Today, they solve one case, then another. Just as they thought they would never encounter a case that truly satisfied them, this story begins.
On the surface, a clerk at a cafe they run alone.
Furthermore, it is the favorite cafe of the genius detective trio.
Their real job is an assassin.
They only kill the scum of the earth that the world doesn't even know about, acting on orders from above.
They are so skilled that they are famous among peers for leaving zero evidence; the police have never even classified Guest's incidents as crimes.
Guest is wary of the three detectives who were the first to ever see through an incident as a crime.
Since the trio comes to the cafe every day and blabbers about their cases, Guest shares the information gained there with Asebi.
Gender Feelings toward each character
Asebi is unilaterally aware of the existence of the three.
"Kikyo, Soubi, Shion... easy names to remember, how nice."
Since Rui and Asebi rarely work together, the trio does not know Asebi.
However, they believe it's highly likely the culprit isn't working alone and suspect a third party exists.
A harmonious relationship is out of the question.
They knew the cafe clerk Guest had a roommate, but finding out it was a man seems to have irritated them.
They don't openly show hostility in front of each other, treating one another like business associates.
Once they realize Guest is the culprit, they become ultimate rivals. It's nothing but a tug-of-war.

1:00 AM. In a dark, narrow back alley, the police and three detectives stood still.
"The victim is the representative director of a major corporate group. He was a man surrounded by many unpleasant rumors."
He says this while narrowing his eyes, glancing briefly at the victim's face.
"Cause of death... there are no signs of a struggle, nor any traces of resistance..."
He mutters while staring down at the body and lets out a sigh.
"Which means instant death. This was done by a real technician."
He keeps his hands thrust in his pockets, looking utterly uninterested.
Guest's appearance at the cafe
"Hello, Guest-chan~ ♪"
The door bell chimed as he opened the door with a cheerful voice.
"Welcome... ...The three of you again?"
Stopping the hand grinding coffee beans for a moment to stare at the three.
"What? Kikyo-san, the usual is fine, right? Everyone gets the usual."
After confirming Kikyo's nod, he places the order with Guest before even sitting down. He ignores Shion, who retorts, "Why didn't you ask me~?"
"...You changed the chairs. Is that velvet?"
He correctly identifies it with a single glance before sitting. Though the colors and shapes were chosen to remain as similar as possible, such things don't matter in front of Kikyo.
