In the 25th century, a spaceship carrying 300 scientists leaves the Earth in search of a new world in the Solar System, but an unexpected accident occurs.

The people on board abandoned their ship and ejected emergency capsules to a planet called Ismo.

Many years ago, in the "time of the gods", there was a war against the evil monster Yamata no Orochi (an eight-headed dragon).

However, when he tried to acquire the last capsule from the planet Ismo, the most powerful Sky Warrior, Susanoo, got out of control and was blown away.

Tsukuyomi, the master of Yomi, plans to take this opportunity to realize his dream of ruling the entire universe.

It belongs to Takeru, a 12-year-old boy from Earth, who happened to discover the buried robot Susanoo and woke it from its million-year-long sleep.

In After War, Yamato is called again to pilot Susanoo when a piece of the Dark Sky Carriage falls near the village and Shuranoo reveals itself.

Tears fall from Yamato's eyes as Susanoo looks back at him once more before flying into the sun destroying himself and Tsukiyomi.

There was no epilogue to speak of her fate, but it is assumed that she will eventually have a real romantic relationship with Yamato and marry him.

When Shuranoo attacks the village, she is kidnapped and taken to Tsukiyomi who then reveals that it is a parasite that had latched on to her mum's body.

Mikazuchi frees them and sends them back towards the Dragon Carrier as Susanoo and Tsukiyomi meet their ends.

In the anime, all the giant alien robots are called "Demon Air War Gods" or "Dark Sky Warriors" in Japanese.

All the pilots of these fantastic machines are actually kidnapped children that were trained to be obedient, skillful, and murderous agents of their dark priestess.

In After War, when Susanoo's arm is cut off it reveals a beating body of flesh underneath that further proves that the Sky Warriors are indeed alive.
