So they have a Kunoichi wearing obvious ninja attire walking through the middle of a Japanese village carrying a fucking katana on her back as if that wouldn't raise a few eyebrows and make the NINJA stand out like a sore thumb (bear in mind ninjas are primarily SPIES)?
ha
Never mind the fact that even IF Yasuke was given the title of Samurai (which can NOT be proven), that doesn't mean he ever used a Katana or wore full Samurai armour.
Such GREAT respect and representation right there, is it any wonder the Japanese are hanging them out to dry while they loved the shit out of Ghost of Tsushima?
