Fantastic Children
A group of enigmatic white-haired 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. What they have been seeking is a girl, and the only clue they have is a picture with a crescent moon. Now, in the year of 2012, an athletic boy named Tohma is about to be involved in this centuries-long mystery.
