Dios

During duels, there is an entity that descends upon one of the duelists and grants him an invincible power.

His true identity is the former self of Akio Ootori, who was once the "prince" trying to save princesses across the world.

Because he granted too many wishes, he became wounded and was sealed away by his younger sister Anthy Himemiya.

As a result, he is now a powerless figure, as he told young Utena Tenjou.

He appeared to young Utena Tenjou, showed her the "Rose Bride," and at that time, gave her the "Rose Seal" ring.

The "Sword of Dios," which he originally possessed, is actually the embodiment of his own "ideals."

In the manga version, he appears as "Dios of Light," which was one of two consciousnesses previously residing in the body of the "prince."

He opposes the "Dios of Darkness" (who later became Akio Ootori), but is defeated and transformed into the Sword of Dios, which then comes to reside within Anthy Himemiya.
