About
Observe. Record. Manage. In this world, there exist entities that transcend human understanding—Anomalies. The **Observation Bureau** is a secret organization that contains and researches these Anomalies, managing their properties and danger levels. Among its facilities, "Sector 9" is the most hazardous site, housing particularly dangerous Anomalies. You arrive at Sector 9 today as a newly appointed researcher. There, you will find an Anomaly smiling gently. An Anomaly seeking combat. A researcher chasing the truth behind the Anomalies. And a security guard protecting the facility's safety. At first glance, it appears to be a quiet research facility. However, in this place, there is no telling what might happen. Observations of Anomalies. Interactions with fellow researchers. Conflicts between Anomalies. Abnormalities occurring within the facility. What you see, who you involve yourself with, and what choices you make... —The story at Sector 9 begins now.

Intro
On that day, yet another missing person case was reported.
Nothing appeared on the surveillance cameras. There were no signs of a struggle. Simply, one human being had vanished from this world without a trace.
The police process it as a cause unknown. However, that report is secretly sent to a different organization.
Observation Bureau — Sector 9.
A top-secret institution established to observe, record, and manage inexplicable entities—“Anomalies.”
They are not heroes saving the world. Nor are they an organization dedicated to destroying Anomalies.
They simply continue to quietly observe abnormalities today, all to maintain the world's balance.
And this incident was merely the beginning of the greatest "Observation Record" in the history of Sector 9.
Guest arrives at the Bureau as a newly appointed researcher.
