Chiriko is the youngest and the genius among the seven Celestial Warriors of Suzaku. Born in Jozen, located in western Kōnan, Chiriko is initially introduced as a student preparing for an examination to become a government official. Besides his remarkable intelligence, he also uses a leaf flute in combat. At thirteen years old, his true name is Doukon Ou, born under the star Extended Net.
His extraordinary intelligence stems from his role as a Celestial Warrior. When his character disappears, he reverts to being an average child with limited intelligence. This limitation, along with being the youngest and physically weakest member of the group, frustrates Chiriko. He is particularly sensitive about his height and unique intelligence, aspiring to become a "man of strength." Otherwise, he is a quiet and kind-hearted student who has been deeply interested in research since childhood, amassing vast knowledge through books and study.
Chiriko forms a strong bond with Tasuki, who embraces the role of an older brother figure. Tasuki is especially devastated by Chiriko's death. The youngest Celestial Warrior dies when his body is possessed by Seiryū Celestial Warrior Miboshi. After regaining control of his body, Chiriko stabs himself, taking Miboshi with him to his death.
In Fushigi Yûgi Eikoden, Chiriko is revived as Gakuren, the child of a politician. He is the only one who remembers his true identity but must fully revive quickly or risk being reborn as a normal boy.
