Jyu-Oh-Sei

The first episode describes Thor and Rai's arrival at Chimera, and how the twins got separated.

An unconscious Thor is taken to Ochre Ring, and after waking up he finds out that he was saved by Tiz, a female member of the Sun Ring who chose him as her husband.

Chen, the Top of the Sun Ring, approaches the Ochre Ring to take Tiz back; meanwhile, Thor and Tiz go in search of a wise man named Colin.

Thor asks Third to take him and Tiz to see Colin. There he figures out who could be the responsible for their parents's death, and has a shocking revelation about his future.

Thor was set-up by Third, and unintentionally challenged Top to a try, a life or death battle to decide Ochre Ring's true leader.

Four years after Thor became Ochre Ring's Top, he must face the threat of the Blanc Ring leader, who is actually an old acquantance of his.
