In this epic battle, it appears that Furinji Hayato would come out on top 5 to 1. Even though the Elder would not kill his opponent, he is armed with unreal power and 108 secret techniques he developed. The Elder is easily Yujiro's equal in physical prowess, so it would eventually boil down to the level of skill each possesses. This, I believe, would be Yujiro's downfall, because he tends to favor using strength rather than tactics or abilities. I think it would be a hard-fought battle on both sides, but Furinji Hayato would eventually come out on top.
10,000 points to anyone who can draw a really good doujin (fan-comic) about this epic battle.
That's all for today. Until next time, good luck and train hard!
