Then an alien species, Victim, attacks the human colonies leaving only one planet, Zion. In an effort to stop Victim from destroying the last planet a training school, GOA, is set up to gather boys from the Zion colonies and train them to become pilots of the Ingrids AKA The Goddesses, five fighting robots that protect Zion. The boys must possess a rare blood type, EO , as well as a special ability, or EX. Zero (Candidate 88) has just arrived in GOA when he falls into the cockpit of the Ingrid Eeva-Leena. Since the synch between pilot and Ingrid are very sensitive everyone believes the Goddess will kill Zero in an attempt to synch. Just before Zero passes out he makes a full synch with the Goddess. Before he can find out more about the incident, his pilot training begins.

Around the the 37th year of the Meiji Era (1904) in the midst of the Russo-Japanese war, the small Japanese army, in need of assistance, uses its special flying (thanks to a benevolent demon) ship, the Amanohara, to attack Russia’s major base at Port Arthur (Lushun). Umakai Shintaro, a Russian diplomat originally from Japan, defects and goes to Sapporo to teach at a girls academy. However, that girls academy is not typical – it is on board the Amanohara, and the five girls Shintaro teaches are known as the Raimu Unit – girls with the ability to summon powerful beings to fight for them. Shintaro eventually becomes their teacher and general in battle, and so the six embark on a weird and excessively erotic journey, as Shintaro helps the girls overcome their weaknesses, become stronger for the final stand at Lushun, and also understand the motives of the “Russian Spiritual Corps” that assist the opponent, which, unfortunately, has one member whom Shintaro knew well….
