Ein schwarzer und ein weißer Mechanoid tauchen auf. Ein Angriff auf Prinzessin Lashara? Doch als ihre Untertanen einen der Mechanoids konfrontieren, finden sie einen Jungen vor – eine große Seltenheit.
Kenshi Masaki, a 15-year-old boy who controls the white Seikijin, is ordered by a masked man to kill Lashara Earth, the ruler of the Shitoreiyu Empire, in order to return to his world. Chiaia Furan, Lashara's bodyguard, pilots her Seikijin and faces off against Kenshi, but loses overwhelmingly to his power even with the assistance of Wahanly Shume. After deciding not to kill the Princess, Kenshi is taken captive and held prisoner. While being held, all the girls are surprised at how Kenshi, a male Seikishi, has been able to do what he can until Doll rescues him and takes him back. The leader decides to eliminate him, but Kenshi easily takes his henchmen out with his martial arts and escapes. When he returns to Lashara with Aura Shurifon's aid, he catches a feverish disease called Rhodeshiya Tore, which Ulyte states that he will die in the next six hours if they don't treat it.
