Yang, First of the Twins, son of Estaphis, is an angelic like Sage - placed as the Guardian to Heaven's Gate. Unknowingly, before he was born, he selfishly took the pure essence of his mother to become a holy being, leaving his brother to have a mischievous and sinful nature.
Yang enjoys reading and has his own library full of books where he leisurely appreciates a cup of tea as he soaks his mind in stories. As well as involve his thoughts into fables told by others, he also writes general education books for Kenjin Doa. One well known book is called "Goku's Theory" which the Sage of Wisdom had expressed his thoughts to Yang in order for it to be dispersed in the lands.
Just because he is a holy being does not mean that Yang has no faulty nature, he tends to be selfish when it comes to sweets Cakes, Cookies, Candy, Pie - He loves them all!
It is very rare when the Guardian to Heaven's Gate does not wear a smile. He is full of warm attributes and extremely kind as one could imagine. Most of his attention is directed to taking care of his brother in concern, helping him not get into too much trouble. He is sometimes found chilling at Levi's beach house with Rowen, Ixe and of course the bubbly Water Sage.
