Fushi is a shapeshifter that can take the form of characters he meets and even objects. He mainly takes the form of The Nameless Boy. For tagging purposes it's impossible to distinguish between these two characters in a post except for scene references where it's clear that it's not Fushi, so both characters should be tagged. You can search for fushi -the_nameless_boy_(fumetsu_no_anata_e) to find Fushi in other forms. Fushi may also take the form of the boy's white wolf, Joan. It's also impossible to tell if the wolf is Fushi or not when they are both present in a post.
