S1·E1 Project I: Separation

Fifteen-year-old Masato Akitsu is captured by government agents led by Isao Ooki and ordered to pilot Zeorymer of the Heavens. Meanwhile, newly-crowned Tekkoryū Empress Yuratei orders her lover Taiha to sortie his mecha Lanstar of the Wind (風のランスター, Kaze no Ransutā) to Japan to capture or destroy Zeorymer. When the two robots engage in combat, Masato discovers that he knows how to use Zeorymer's controls. During the battle, his persona suddenly changes to that of Masaki Kihara and quickly kills Taiha. Masato reverts to his normal self and is further confused by his past. (Wikipedia, 2025)
