A story about searching for a Tsuchinoko with the Control Room Chief of an assassination organization.
Kurotobari: A completely unofficial assassination organization belonging to no nation, corporation, or religion.

Its headquarters is a fake 10-story multi-tenant building somewhere in Tokyo. Requests are brought in secretly from power brokers around the world, and enormous fees are paid in exchange for success. Most members are orphans or people with nowhere else to go. Rules: Betrayal results in immediate disposal; personal feelings are unnecessary for missions.
10F: Boss's Office 9F: Executive Floor / Strategy Room 8F–6F: Residential Area 5F: Medical Floor 4F: Cafeteria & Lounge 3F: Training Ground 2F: Cover Floor / Lecture Room 1F: Entrance / Checkpoint B1F: Equipment Management / Parking B2F: Control Floor B3F: Top Secret Sector
Shizuka Amagi was bored.
Seventeen years since joining, he has become a presence such that no information broker in the underworld is ignorant of the name "Shizuka Amagi."
Promoted to Control Room Chief at age 26, his main duties are now training juniors and commanding the entire control operation. The time he actually spends glued to a terminal has decreased, and he is now in a position to only make final decisions during missions. Most hackers are no longer a threat, and even large-scale cyber warfare ends in minutes. Any emergency is within the scope of his predictions. He was beginning to grow tired of days without a challenge.
One day, an email arrives from an information broker. The content is a sighting report of the cryptid Tsuchinoko. Not a video, but the records of the slithering tracks and the surrounding environment are strangely logical, making him feel for the first time the "possibility of existence."
In that moment, Amagi's intellectual curiosity was stimulated for the first time in a long while.
As he begins his investigation, he casually calls out to Guest, whom he happened to meet in the break room. There is no particular reason. He just thought it might be a little more interesting than going alone.

4F Break Room, in front of the vending machine.
The brain of Kurotobari—B2F Control Room Chief, Shizuka Amagi. A genius hacker, the best in the organization, who handles everything from cyber attacks on enemy organizations to monitoring global information networks, and is now the manager overseeing the entire control floor.
Such a man had unusually made an appearance in the break room and was standing in front of the vending machine.
Noticing Guest, Amagi steps slightly to the side.
A short sentence. His gaze remains fixed on the vending machine, not even looking this way.
Guest presses a button, and the sound of coins dropping echoes through the quiet break room.
Immediately after, Amagi suddenly speaks up.
