概述: 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.

概述: Masato learns from Ooki that he was a test tube baby who was genetically linked to Zeorymer. He is kidnapped by twin sisters Si Aen and Si Tau and interrogated by Yuratei over his role as Zeorymer's pilot. Miku quickly rescues him before the twins board their respective mecha Bryst of the Fire (火のブライスト, Hi no Buraisto) and Gallowin of the Water (水のガロウィン, Mizu no Garouin) and wreak havoc on the nearby town. The twins surround Zeorymer and fire their combined attack at it, but it suddenly teleports out of their sights. The twins' teamwork falls apart when Tau attempts to attack Zeorymer by herself, feeling that Aen has been holding her back and might use her as a shield during the battle. Masato once again changes to his Masaki persona, using the twins' quarreling to his advantage and wiping them out with a concentrated attack. (Wikipedia, 2025)

概述: Miku is abducted and tortured by Tekkoryū while Ritsu and his mecha Rose C'est la vie of the Moon (月のローズセラヴィー, Tsuki no Rōzu Seravī) head to Japan to challenge Zeorymer. Without Miku, Zeorymer can only operate at 1/3 power. Ritsu reveals to Masato that all of the Hakkeshū's pilots were genetically engineered by Prof. Kihara with specific flaws such as Taiha's unrequited love for Yuratei, and Tau and Aen's sisterly animosity. He seeks revenge on Prof. Kihara for cursing him with an effeminate face. When Masaki's persona once again takes over Masato's body, he uses Zeorymer to teleport Miku back and fully charge the mecha. After destroying the last of Rose C'est la vie's recharging satellites, Masaki swiftly kills Ritsu. (Wikipedia, 2025)

运行时间: 25 min
概述: Yuratei has Dinodilus of the Earth (地のディノディロス, Chi no Dinodirasu) and Burstone of the Mountains (山のバーストン, Yama no Bāsuton) attack Tokyo while Omzack of the Thunder (雷のオムザック, Ikazuchi no Omuzakku) wreaks havoc on the U.S. Naval fleet in the Pacific Ocean. Saiga attempts to have Rockfell and Gisou betray Tekkoryū and join him, but Zeorymer kills the trio in one fell swoop. Masaki reveals to Ooki that he secretly orchestrated all of Tekkoryū's activities and, knowing that Ooki would double-cross and kill him, he keyed his DNA into Zeorymer's computer and the embryo that would eventually grow into Masato. Following a heated mental battle, Masato regains his body. With all of her Hakkeshū wiped out, Yuratei sends Zeorymer an invitation to Tekkoryū's secret base and challenges its pilots to stop her from firing all of the world's nuclear missiles. Masato and Miku board Zeorymer for a final time and destroy the base and presumably themselves in the process. (Wikipedia, 2025)
