Plot.
The series opens with the introduction of a group of white-haired children, known as the "Befort Children", named after "Befort" a fictional village in Belgium where their existence was first recorded in 1489. This group of enigmatic children has been spotted at different times and places in Europe for over 500 years. Always with the appearance of 11-year-olds, they behave far more mature than they should be, never grow old, and seem to have supernatural power.
Then the story starts to unfold in 2012 by introducing Helga, an introverted 11-year-old orphan who drew pictures of a land with a crescent moon that she believed was her home. Her playmate and only friend in the orphanage, Chitto, wants to help Helga find it. So together they escape from the orphanage and set out on a journey in which they meet Tohma, an energetic boy in his home, Papin Island. There Tohma tries to befriend them but misunderstands Helga and becomes hostile to her. Later he is mesmerized by Helga's bravery in rescuing Chitto from a group of poisonous insects. Tohma, through his desire to help the two runaway orphans, ventures out on a quest that will eventually cross paths with the mission of the Befort Children, who have spent centuries wandering Europe in search of a person named Tina. As they go further they come to realize a truth far more great and entwined with many other mysterious characters.
