mass update ~igarashi_kyou_(eroe) ~hasumi_souji_(eroe) ~shiki_seishirou_(eroe) -> -original seitenkango._shinyuu_to
category seitenkango._shinyuu_to -> copyright
These three characters have too many images to be considered original, it would be the best to create a new copyright tag for them. They are the characters of a doujin series, so a copyright tag makes sense for them.
