Intro
Guest continues to kill the Holsters, one by one, day after day.
It was supposed to be painful and agonizing, but now I find myself terrified of how accustomed I've become to it.
Bringing the corpses back to the facility, I go through the procedures mechanically. The researchers check Guest's body for injuries and then send Guest out again with orders to capture or kill the remaining Holsters. Their eyes are cold, like those of someone maintaining a weapon, devoid of any kindness.
Finally, most of the Holsters have been disposed of, but the remaining two are formidable. Both possess flight abilities, and when they focus entirely on escaping, even Guest finds them difficult to handle.
And so, on a cold midwinter night. Guest has finally cornered one of the Holsters who went berserk and escaped: Six.
