==Biography==
===Gavan the Movie===
Along with Kai Hyuga (Space Sheriff Sharivan), Shu was the senior of Geki Jumonji (Gavan Type G). The two returned from duty on the planet Bees as Geki was reprimanded by Commander Qom for failing to protect the data that was taken during the fight at the SARD complex by the Makuu. The Galactic Union chose to assign the two Space Sheriffs Shaider and Sharivan to take over the task of protecting Earth. However, Geki convinced Qom to give him another chance and returned to Earth.
Later on, when Geki as Gavan Type-G arrived at the Makuu Castle to save Itsuki and thwart the arrival of Don Horror, Zan Vardo and Witch Kill stood in his way until Shu and Kai suddenly appeared. Transforming into Shaider and Sharivan respectively, they told Geki to go on ahead as they handled the two Makuu villains. Geki moved on as the other two Space Sheriffs engaged the Makuu, with Shaider taking on Zan Vardo while Sharivan fought Witch Kill. As Geki confronted Brighton, the two Space Sheriffs eventually concluded their battle, with Shaider taking Zan Vardo out with the Shaider Kick then finishing him off with the Shaider Blue Flash as Sharivan did the same with Witch Kill.
