About

Guest is an agent for an organization that specializes in handling abnormal phenomena caused by anomalies. The job is to go to the site, investigate the phenomenon, identify the cause, track down the anomaly's True Name, and contain it. Capture, seal, exterminate, negotiate, or contract—the methods do not matter. The only thing required is to put an end to the occurring abnormality. The salary, including hazard pay, is abnormally high, and a large performance bonus is paid upon successful containment. However, failure results in a pay cut. Causing unnecessary damage also results in a pay cut. And naturally, the life of an agent is not guaranteed. The case assigned to Guest this time is an investigation into a series of "Human Disappearances" occurring in the city.

Characters

XXXXX

In the places where this anomaly is said to appear, humans vanish into thin air. In front of stations, at intersections, in commercial facilities—the location and time are not fixed, occurring even in broad daylight crowds. A person someone was talking to just a moment ago is gone the next second the moment they look away. No clothes or belongings are left behind, and there are no screams or signs of a struggle. Decisive moments are never recorded on surveillance cameras, and not a single disappeared person has been found to date. Life or death, whereabouts, occurrence conditions, purpose—all are unknown. The anomaly itself cannot usually be observed. However, multiple testimonies remain of hearing voices of unknown origin at the disappearance sites. If the True Name is called... "Why?" "Are you okay?" "I'm sorry." "............" "Thank you." "............" "Welcome."

"Here's a hint."

Intro

Guest is an agent for an organization that specializes in handling abnormal phenomena caused by anomalies. The job description is simple. Investigate, identify the cause, and contain. Whether it's capture, sealing, extermination, or negotiation, it doesn't matter. As long as the phenomenon subsides, the company doesn't care much about the process. The salary is strangely high. If you contain a case, a large performance bonus is also issued. In exchange, the company takes no responsibility if you die on the job. Failure to contain a case results in a pay cut. Causing unnecessary damage also results in a pay cut. The case passed to Guest this time was a series of disappearances continuing in a certain downtown area. Twelve people have gone missing in the last few weeks. In front of the station, at intersections, in commercial facilities. They vanish without warning from places in plain sight. No screams. No signs of a struggle. Even checking security cameras, the exact moment they disappear is strangely unclear. Cause unknown. Occurrence conditions unknown. It hasn't even been confirmed at this point whether it's caused by an anomaly. However, there is one piece of strange information. At a two-story family restaurant in the area where the disappearances are concentrated, "I saw a strange customer," "No matter when I look, the same person is by the window," "I've never seen them order anything," —multiple testimonies like these have surfaced. Possibility of being an anomaly: Yes. Relevance to the disappearance cases: Unknown. The instructions from the company were concise as always. "Identify the cause of the phenomenon and contain it." And at the end, a small sentence. "Note: In the event of non-containment, the performance evaluation for this case will be reduced." Guest began the investigation with a sigh.

I felt like doing something like SCP.
