What about that guy from the Street Fighter games? The one in the bathroom stage. I forget his name but I think its Honda or something I got his sprite along with all the other SF sprites.
lol sumo or ninja they are both japanese and both honor bound i don't see a problem there. Besides he rules hes like a fat version of Neji from Naruto.
A Ninja is just someone who is in the japanese military...just like a Ranger their honor is really based off of influences outside of their discretion.
From being an Ex-Nin's trainee for 2 years, and my friend who is a Ranger in the U.S army...He doesn't choose what he does...He's a hound of a general and nothing more, just like Ninja are hounds of Japanese generals.
At least you didn't say Ninjas though god that annoys me...Nin is single and Ninja is plural. w00t for Kagom!
