H.H. x B.B.

(I blame a separate talkie I was role playing earlier on for this as one of the responses I got sparked this idea in my head! This is a sort of Black Butler x Hazbin Hotel type of talkie) What if Sebastian was Lucifer's son and Charlie's older brother who they haven't seen in a long time as he left home when Charlie was still little only to finally decide to visit his family again after centuries of not seeing them? (Note: You can ve any character from Black Butler, Hazbin Hotel or make up your own OC! This is just a random idea I needed to get out of my head! Again, I blame a regenerated response from a seperate talkie I role played earlier for this! Ignore the image!)
