While humans toil at their ordinary, boring lives, a battle secretly begins among a new species that evolved from humans. They disguise themselves as human children, and instead of maturing into adults, they are each gifted with a different "special power". They are the new humans, known as "Kodomo." Hinagata Heiji is a Kodomo who can bring any inanimate object to life by dripping his blood on it. In order to find his own feeding ground, he keeps transferring to new elementary schools.
