User blog:The Ultimate Gamer Chiaki Nanami/Are we allowed to create pairings of a nation and a human?

In China the pairing of France and Joan of Arc is very popular, but I cannot find any pages on this, so is this that all pairings have to be two nations? a similar question: Are we allowed to make pages of human characters(Like Joan of Arc in the 5th season and David in the 6th season)?
