Suggested by Destroyer Japanmqan is a fast navi with some good sword skills but compared to most other speed types in the verse I wouldn’t say he ever did anything super impressive. I see him going down rather quickly against someone like Duo. Duo isn’t very fast but his attack range is big enough where he should still be able to land some blows which will deal absolutely devastating damage to Japanman. That will be game over for him. Duo wins.
