Shuraiya

シュライヤ

Shuraiya is an anime-original character who appears in episode 36 and episode 37. He is a prince from a far away kingdom.

He went to Seiyo Academy to find the Embryo and prove to his father that he is more skilled and better than him and at the same time, to find a bride. When he saw Amu purify an X-Egg, he decided to make her his bride, but she turned him down at every turn. Yukari and Utau gave him a pendant that they claimed was the Embryo. As he wore it around his neck, he gained power from X-Eggs ad ran amok in the woods of Seiyo Academy and began to lose himself. But thanks to Amu and his loyal servant, Pearl, he managed to return to good and later returned to his country. As a person, he has an arrogant and demanding personality. When Tadase undergoes Character Change, their personalities become identical. His Guardian Character is Ramira, created from his wish to be a strong king like his father.
