well, of course the ninja would. but there probably wouldn't be a fight though, cause well let's face it.... ninja's are going to be like, "whatever man, it's too easy, i'm not gonna waste my time..." so there ya go...
In fact, there is good evidence that ninjas were good all-around warriors. For instance, take the ono, the ninja battle axe. While useless for stealthily killing targets, it was used to smash down castle doors and mounted enemies. Something to think about!
