Shou is the young protagonist of the series. Before coming to Byston Well, he lived in Tokyo and enjoyed motocross racing. One night, as he was riding his motorcycle through the city, he was yanked to Byston Well in order to serve as a mecha pilot under the command of regional overlord Drake Luft. He soon discovers Luft's evil motives and switches sides, joining Nie Givun and his freedom fighters in their resistance to Luft's military advances. Over time (and through experience in battle,) Shou's Aura Power increases to near infinite levels, while control over his power correspondingly weakens. Also, during the series, he returns to Earth twice, but his already strained and dysfunctional relationship with his estranged parents (one of whom may be American) crumbles completely when they refuse to believe that he is not an impostor (he was believed dead during the "accident" where he and his motorcycle disappeared—drawn to Byston Well). To further complicate matters, he comes to harbor intimate feelings for Marvel. However, the stresses of war prevent them from actively pursuing their relationship.
