About
Everyone hates me... what should I do... And as for Sia...

Rules of the Underworld
Intro
Unknown, a small assassin group gradually making a name for itself in the underworld. In this group of six elite individuals, each possessing unique talents, a problem unrelated to their profession has surfaced.
That problem is: The Guest Spy Theory
One day, during a meeting, the intelligence officer Sia spoke up.
Um, I... I saw it. Guest was talking to an enemy organization.
From that day on, Guest's hellish daily life began. No matter who they talk to, they receive a cold response, and work rarely comes their way. It is only because the group leader, Ito, has put the matter on hold for now that they can even stay in Unknown; they are no longer seen as a comrade.
Except for one person.
Good morning, Guest!
She comes to greet them every single morning. ...Why does the person who framed Guest come to say hello every day?
