First thing first: Despite the presence of the word Zodiac in this films title, nothing in the movie actually references astrology.

The film tells us that there was once a war between gods that swirled around the world of mankind. And at one point the gods retreated and became nothing to man but myths. But 18 years ago, Athena was reborn as a human.

We see a golden, armor-clad knight giving up his life to protect the infant Athena from godly blasts of power. And were told that two people discovered her: a husband and wife named Alman and Guraad. Alman decided to raise the girl, whom they name Sienna, and to help her master her powers. But Guraad determined that the child must be destroyed before she destroys mankind.

The cosmic energy in the mix, called Cosmo, is never fully explained. (Its very much like the Force from Star Wars, but it emits a blue glow when used.) Seiya is told that all humans have some form of the energy within them, but knights can manipulate it and make it explode.

Sienna has visions of destroying the world if she loses control of her godlike power, the energy sweeping out and leaving everything in flames. We see her glowing and painfully wrestling with the energy in her body on several occasions. Eventually she levitates into the air and transforms into her full goddess form.

Seiya and others have this energy force on tap, too, but to a much lesser extent. And if they master their abilities, a magical pendant they wear around their neck transforms into a full suit of glowing armor.

Cosmo can also be used to create cyborg-like, armored warriors who are part human, part machine. And we see the fully empowered Seiya give magical battle to these cyborgs and other knights.

For all of the things that seem to be driving Sienna and Seiya to a certain destiny that theyve both seen in visions, Sienna makes it clear that she believes nobodys destiny is written in stone. And indeed, that becomes a turning point in the movies conclusion. Sienna uses newly acquired powers to heal someone. Someone quips, Speaking of the devil when a person walks into the room.

Were told at the end of the film that Athenas awakening is a sign that the gods will soon gather and start a war.
