Grandmaster Yufang (老道士 虞翻 Rōdōshi Guhon) is Rin's great grand-uncle and Master Kaku's mentor, who tends to be bizarre at times and often cracks his neck. Gave the Dairangers the Dairenkens and constructed the Chi-Power Bazooka. His fiance, Shoukyou, brought him Byakkoshinken which he placed within a stone until the rightful owner (Kou) could remove it.
