Historical emperors are fair game. At least far enough back, meaning roughly 100-150 years. The Showa Emperor (Hirohito) is not yet fair game, but his father, the Emperor Taisho, has been fair game for some years now. Though as far as I remember, they still don't acknowledge his weirdness. The man seems to me to have been severely autistic.

Emperor Komei will be a relevant character in the next volumes.
