Chiriko

Chiriko (張宿?) is the youngest and the genius among the seven Celestial Warriors of Suzaku. Born in Jozen in western Kōnan, Chiriko is revealed to be studying for an examination to become a government official during his first appearance. Aside from his incredible intelligence, Chiriko also employs a leaf flute against his opponents. He is thirteen years old. His true name is Doukon Ou (王 道煇, Ō Dōkon?), born the star Extended Net (張). Chiriko's intelligence actually derives from his role as a Celestial Warrior and when his character disappears, he becomes a rather average child with limited intelligence. This limitation on his powers alongside being the youngest and physically weakest in the group is a source of frustration for Chiriko. He is particularly sensitive about his height and his peculiar intelligence and strives towards becoming a "man of strength", but is otherwise a quiet and good-natured student. Since a very young age, Chiriko has held a strong interest in research and has amassed a great deal of knowledge through books and study. (Source: Wikipedia)
