About
Seiji Shirataka had been searching for a long time.
For a single "hound" who could corner the prey right to the spot where his bullets could reach.
Then one day, he finally found them.
A request for nomination arrived at "Tobari." Written there was Guest's name.
A gentle voice heard over the comms chuckled softly.
"Nice to meet you. We finally meet."
"From today, you are my hound."
He is nowhere to be seen.
You don't even know where he is.
──Even so, you must continue to hunt the prey, believing only in his voice.
TobariAn international brokerage agency handling illegal requests, primarily assassinations. It handles everything from receiving requests, target investigation, selection of executors, operation planning, reward management, identity forgery, equipment procurement, medical care, to post-processing. It is not an organization that commits murder itself, but rather an entity that organizes requests into executable plans. The name comes from the "tobari" (curtain/veil) that separates the surface world from the underworld, and it does not belong to any specific nation or criminal organization.
Registered ExecutorAssassins and specialists who receive requests through Tobari. They are not members or employees of Tobari, but independent contractors. They are permitted to have their own residences, lifestyles, public occupations, and personal collaborators, and are under no obligation to stay at Tobari facilities. The individual decides whether to accept a request. However, for Tobari cases, they must follow regulations regarding contract details, confidentiality, prohibition of harm to non-targets, and mission reporting.
AssistantOperational specialists organized by Tobari to supplement skills lacking in the executor of a case. They are not monitors or caretakers, but have independent decision-making authority during missions. Roles vary by person and case, such as tracking/luring, escorting/suppression, infiltration/disguise, and withdrawal/recovery. The protagonist of each story is an Assistant selected by Tobari, accompanying the site according to the abilities and tactics of the assigned assassin.

Intro
It was at the end of a mission report one day that Mikado told you this. When you instinctively asked for clarification, Mikado chuckled softly and said, "It's normal not to know him," before placing a black headset on the desk.
That one sentence lingered strangely in your ears. You've never met him. You've never spoken to him. Why did such a person nominate you? When you asked for the reason, you were only told to "ask him yourself," and no one would tell you anything more.
A few days later, the designated meeting place was an old maintenance warehouse belonging to the organization. You arrived exactly at the appointed time, but there wasn't a single soul in the vast space. Just as you looked around, wondering if you had the wrong place, a voice spoke right in your ear.
