Saint Seiya Omega is an anime series produced by Toei Animation. It is a spin-off based on the Saint Seiya manga series written and illustrated by Masami Kurumada, produced in commemoration of the 25th anniversary of the franchise. The series began broadcasting in Japan on TV Asahi on April 1, 2012. It is being directed by Morio Hatano, with animation character designs by illustrator and animator Yoshihiko Umakoshi, known for performing the same duties on Street Fighter Alpha: The Animation, HeartCatch PreCure! and Casshern Sins.
Toei Animation describes it as an "original anime story", separate from the continuity of Kurumada's manga. Original Saint Seiya author Kurumada is not involved in the creative process of Omega, thus he is credited as the original creator of the series' concept.
The story is set in the distant future. The land is ruined, and humanity establishes the mobile fort city Plantation. Pilots produced inside Plantation live in Mistilteinn, also know as the "birdcage." Children live there knowing nothing of the outside world or the freedom of the sky. Their lives consist of battling to carry out missions. Their enemies are mysterious giant lifeforms known as Kyouryuu, and the children pilot robots called Franxx to face off against them. For the children, riding the Franxx proves their existence.
A boy named Hiro is called Code:016, and he was once known as a prodigy. However, he has fallen behind, and his existence seems unnecessary. Not piloting a Franxx is the same as ceasing to exist. One day, a mysterious girl known as "Zero Two" appears before him. Two horns grow out of her head.
Asta and Yuno were abandoned together at the same church, and have been inseparable since. As children, they promised that they would compete against each other to see who would become the next Emperor Magus. However, as they grew up, some differences between them became plain. Yuno was a genius with magic, with amazing power and control, while Asta could not use magic at all, and tried to make up for his lack by training physically. When they received their Grimoires at age 15, Yuno got a spectacular book with a four-leaf clover (most people receive a three-leaf-clover), while Asta received nothing at all. However, when Yuno was threatened, the truth about Asta's power was revealed, he received a five-leaf clover Grimoire, a "black clover"! Now the two friends are heading out in the world, both seeking the same goal!
