The Place I Want to Go
A policeman, Cooks, visits a family where one of the Children used to live, in an attempt to find out what's going on. Helga and Chit are recaptured on the mainland and sent back to Chikao, which please neither of them - especially since Chit is getting sent to another orphanage. A crazed speedboat driver (the man from the first episode with the cryptic ramblings) crashes into the boat carrying Chit, however, and Thoma happens to be on hand to rescue him, so they set out together to rescue Helga once more.

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.
