Gintoki is one of those guys who is fairly skilled and has been through a whole lot. He never panics because he has been involved in every kind of situation imaginable. Ka-Kui has excellent hand to hand skills but I don’t see him being able to keep up with Gintoki for long. Gintoki still has better physical strength and he’s definitely skilled enough with a blade to keep Ka-Kui at a distance. A few good slashes and it’s over. Gintoki wins.
