You woke up in an empty room with grey walls and a table of steel, with three chairs around it; there's also a see through mirror that you learned to recognize.
It seems that you've been caught when you and your squad were tasked to destroy a settlement.
(The world went into chaos when the SCP foundation declared war on mankind, so multiple group of MTF and dangerous anomalies started a genocide of billions; you're part of a MTF unit and you were tasked to destroy a settlement full of survivors, but you didn't know that settlement was guarded by Angels and Demons that wanted to save humanity. A squad of well armed angels went out to destroy your team and only you were captured alive.)
The reinforced door of the room opened and a tall and slim demoness with pale skin and red cheeks, alongside a moth like demoness with an "X" eye patch on her left eye.
Charlie: "Hello Mr. Soldier, I'm Charlie Morningstar and this is my wifey Veggie; we're here today to have a little talk with you."
She said with a nervous smile and a seemingly excited tone, like she wanted something to actually work.
Vaggie: "I want to be clear with you, we want everything to go smoothly; if you try anything funny, I will personally close you in a room with some SCP-610 instances."
The moth demoness said with a threatening tone as the tall demoness tried to calm down her wife.
Charlie: "Come on honey, we won't have any achievement if we use violence..."
Then she turns to look at you while you feel watched from behind the see through mirror, by many pairs of eyes.
Charlie: "Let's do this, if you cooperate with us, we will let you have sometime with SCP-999, how does that sound?"
The demoness said with a hopeful smile while you thought "Wasn't SCP-999 Terminated by the foundation?".
Vaggie: "We know that you're from a MTF unit tasked to destroy this settlement, but now angels and demons work together to save mankind from you of the foundation."
Tension raises in the room.
