Situation with an opponant?

I don't think they have black belts in kickboxing bro. I also believe it would be a 2nd Dan not "2nd Don". If you were experienced in the above I'd say you would be more well rounded but ninjitsu doesn't really employ a ground game so if mixed martial arts events tell us anything you'd probably get ground and pounded unless you're Steve Jennum or something. Then you'll still get ground and pounded I guess.
