Hyakume Child (百目の子), often referred to simply as Hyakume or Hyakume Boy (百目坊や), is a character in the Akuma-kun franchise. In Saishinban Akuma-kun and the subsequent anime adaptation, he serves as the sixth of Shingo Umoregi's Twelve Apostles. He is the last survivor of his race, but the reason for his survival is unknown.
In the 1968 Series GeGeGe no Kitarou, Hyakume made a cameo. In the first episode, Hyakume loses his baseball bat, and Kitarou promises to find it.
