Tetsuya Kouji

Easily excitable partner of Shizuru and pilot of G-Gunner. He spends most of the series recovering from injuries sustained in the battle from the first episode. He has feelings for Shizuru and is a little wary of Shinobu who seems to be getting a little too close to her. He is named after the pilots of Mazinger Z and the Great Mazinger, Kouji Kabuto and Tetsuya Tsurugi.
