A Devil Child is a person who possess the powers of a human and a demon. They are described as "half-human and half-demon" even though they look exactly the same as humans. Devil Children appear in the Devil Children series of games. Devil Children each possess a demon that is their unique guide. This guide absorbs power over time and "evolves", which is something unique to these guides. Devil Children are called DemiKids in the North American version of the game. Their counterparts are Angel Children.
