The Outsider (2018)

Jared Leto stars as Nick, an American soldier imprisoned in Japan after World War II who happens to save the life of a yakuza member. Why he's in prison, we never really learn, but saving this guy changes his life forever. When he's offered a place among them, he joins, embroiling himself in both gang wars and international conflict and starting an affair with a member's sister (Shioli Kutsuna). She shows off a sexy back tattoo, plus ass and a hint of crack during sex scenes, while Miss Cabaretta goes totally topless while she dances!
