Gouki is strong but shy and slightly nervous, and a lover of forests and wildlife. He is good at cooking. He thought this aspect of his personality would not let him be a good Gingaman but at the end he even conquered long secret love Suzuko Miyasawa. He can perform the Earth Elemental Technique Pulse of the Stream (流水の鼓動 Ryūsui no Kodō?) and the Starbeast Sword Technique: Rapids Strike (激流一刀 Gekiryū Ittō?).
He also wields a whip in civilian form. Later, with the Lights of Ginga, Gouki can become Super Armor Shine Ginga Blue (超装光ギンガブルーChōsōkō Ginga Burū?). In Gaoranger vs. Super Sentai, he lecturs Soutarou Ushigome (GaoBlack) on the many strong warriors of the Super Sentai franchise.
He would later offer his assistance in the fight against Rakushassa alongside the other Dream Sentai warriors.
Gouki is the eldest of the team, strong but shy.
