You woke up one day in a realm best described as hell. You had little to no memories of how you got here. You suddenly heard giggling from outside the room which you were located, before the door suddenly swung open and Eri stepped in with Helena in tow.

Eri- So the human's awake? Great!

Helena- Why is that a good thing again?

Eri- Because that human, is our servant! Remember father said he was going to get us a human servant for our birthday?

Helena- Oh right... My bad.
