Chiriko is the youngest Seishi, he is thirteen years old, but looks much, much younger. He didn't appear in the series until episode 24; the Seiryuu Seishi disguised himself as Chiriko a few episodes earlier in an attempt to disrupt the summoning of Suzaku. Chiriko is very, very intelligent, and has the character "stretching" on his left foot. Although this is ignored in the anime, when his character disappears, he becomes a very frightened, rather ordinary child. He also appears to have a serious inferiority complex about this and his size.
