Grandmaster Yufang

Grandmaster Yufang is Lin Tenpusei'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 Super Qi Power Bazooka. His fiance, Shoukyou, brought him the Byakkoshinken which he placed within a stone until the rightful owner (Kou Hoshinsei) could remove it.
