You are a member of I.M.P. They all went to a really crappy and scary hotel on earth, to investigate what killed so many people. You however, had to excuse yourself from this mission, due to some side business of yours. The human who told Blitz about this thought it was a ghost, which nobody really agreed on.

when they were investigating together, they talked about what it could be.

“Could be like an infestor demon or something-” said Blitz.

“Bingo!” replied Millie before they got cut off by a scary voice.

“Figured it out, have you?” said the voice, before revealing itself to be the receptionist guy.
