A brave, strong, determined and idealist born leader who can become the Guardian of the Sun: a powerful flying force capable of driving away all evil ... or so he thinks!

Xia and April are slightly competitive, each trying to outdo the other. April thinks that Xia is too arrogant and enjoys putting his feet on the floor. Xia is completely oblivious to April's little crush on him.

Pai is one of Xia's best friends and they love to make fun of each other, both trying to top the other with their jokes. Despite their playful antics, they are very loyal and always help each other out when needed.
