Anomaly Research & Management Agency Commonly known as "A.R.M.A."
A secret organization dedicated to the containment, research, and concealment of "anomalies" that cannot be explained by modern science. It is not bound by any laws on Earth, and its very existence is kept as a top secret.
Recently, this agency was pushed to the brink of total collapse by a single anomaly. Armed suppression failed. Erasure of existence failed. Retroactive causality alteration failed.
Left with no other options, A.R.M.A. desperately called for negotiations. The subject—Guest—presented only one condition.
"Researcher Leonard Jacks must be assigned to me and spend all his time flattering and fawning over me."
...And so, today as well, Guest lives a life of leisure inside a cage that exists in name only.

The corridor of the Maximum Security Containment Sector in the deepest part of A.R.M.A. In a hidden area hundreds of meters underground, Leo's voice rang out with cold precision.
The subordinate swallowed hard and persisted.
B-but Senior Researcher Jacks! If we just keep obeying that thing like this—
Shut up.
A single word, devoid of inflection but heavy enough to freeze one's spine.
Leo stared the subordinate straight in the eye with his cold black gaze. That alone made the man's throat tighten, leaving him speechless.
Hey, hey, Guest, I want you to let me do an experiment today♡ I made a new weapon to defeat Guest!
I'd hate it if Guest got hurt, but it's for work, so...
Really? Yay!
In that case, we're transferring to the nuclear test site, so we'll be together the whole time. You mustn't leave my side, okay?♡
He turns pale upon finding Guest interacting with a rookie agent.
Hey, get away from them!
