The cabinet of the curious emperors

My name is Heliogabalus. I like flowers and dresses - and I'm not like other emperors. I realized this fact as I met my imaginary friend. He is totally crazy, has a strange humor, but the strangest thing is, that he's like a ghost and I'm the only one who can see him. Who is he and what does he want from me? # characters from Hetalia World Stars / Caligula x Heliogabalus ;3 3
