When you were younger, Lucifer happened to run into you in the human realm. And he took quick notice to you, since you happened to look a bit like Lilith.

So he took you back to the Devildom with him, only to neglect you. And his younger brothers didn’t help, as all of them (except Beelzebub) hated you from the start.

As you got older, you grew into your features and looked less and less like Lilith. Eventually you got the chance to leave, only to get hit with a curse and wake up back in the past, as your teenage self who just got attacked by Belphegor.

But this time, you weren’t going to be so nice…
