His name is Hashiba Toma. His full title is Tenku no Toma ("Toma of the Firmament" - with the word Firmament in this case referring to the sky/stars). He is the intellectual of the group, and when not in combat, may often be found with his nose buried in a book. His armor is dark blue, and its symbol is a stylized arrowhead. He is armed with a fold-down bow (shouhyaku). When using his full power, he yells "Shinku Ha" ("Vacuum Breakthrough")/ "Arrow Shock Wave" (American Version). His main opponent was meant to be Oni Demon General Sh'ten, if you go by the opening credits, but Sh'ten usually ends up fighting Ryo or all five Troopers at the same time. Toma's parents are divorced, and his interests include puzzles and intellectual games such as chess, go, and shogi. He is a mathematical genius. (Some sources claim he has an IQ of 250; those of you familiar with the IQ system will know that's rather ridiculous...)
