It's a fine opening post but it still kind of ignores the speed deficit Yujiro is facing here. He's not nearly as fast as Apachai, Shigure, Hayato or Akisame. Sakaki and Kensei don't have as good speedfeats so I'm willing to entertain the notion that he can keep up with them in combat.
That is, unless I am forgetting some utterly ba-nay-nays speedfeats for Yujiro. I honestly don't think he can keep up with the Ryozanpaku side.
