There's Shaman King, but other than what was already established like osorezan revoir, there was basically nothing (unless you want to count RenxJeanne, but people say there isn't enough evidence/don't like to count Flowers as Canon). Detective Conan is technically shounen, but people like to list it as a Detective Manga so I won't speak about it, ahah.
But for the most part, Pokey is correct.
