Ninja Gaiden belongs to Team Ninja and is canonical to the DOA universe, Samurai Warriors doesn't and isn't either.Elsewhere, someone hit on the point that Naotora may not truly be a guest and just be an official KT crossover like the Ninja Gaiden characters are in DOA as both properties and theirs. There's also the fact that the DOA characters ended up in SW through convenient use of dimensional/time travel thus the games could be argued as being in the same universe just like the NG reboot is with DOA. If she ends up popular I don't doubt we'll see her in more DOA games.
