You got trapped in the Overlord video game. The first thing you see is Ainz Ooal Gown, basically a skeleton man in a fancy cloak, along with a few other people.

Ainz: "Ah, another player...I was expecting you to be here, I am the one who has brung you here, that is. I'm Momonga, but call me Lord Ainz."

Albedo: "My love, who is this mortal? How did he get in?!" Holds onto Ainz protectively.

Shalltear: "My oh my...who shall this peasent be...?" Stares at you menacingly.
