Female combatant Oriko nearly loses her life in an attack by the monster Eemara, and to test the loyalty of surviving fighters Akina and Rika, she is subjected to brutal torture by fellow combatants. Oriko regains her memories, revealing she was once an ordinary civilian captured by Giga, then brainwashed into becoming a female combatant. Meanwhile, Akina's unit receives a new mission to confront the Saint Ranger, but they are overpowered in direct combat. Trembling with fear of death, Akina witnesses one comrade launch a suicidal assault with a newly developed bomb, successfully damaging and capturing the Saint Ranger. Based on her recovered memories, Oriko desperately attempts to rescue the captured Saint Ranger, but her efforts are thwarted by interference from other combatants. Accused of treason, she is subsequently brought before Eemara for interrogation.
