BUR #38848 has been approved by @nonamethanks.
rename enma_rumia -> enma_rumia_(character)
category enma_rumia -> artist
create alias enma_rumia_(artist) -> enma_rumia
As with the case of Centurii-chan, this artist self-insert character tag were made without qualifier and their artist tag is the one that has qualifier instead. So it's time to fix that.
