Hidden somewhere beyond the highest clouds is the castle of Destino, a school for very special students. They're the Melowies, little unicorns born with a symbol on their wings and a hidden magical power.

But Destino is also a place where friendships are born, where the Melowies find their courage, and where they learn their path to growing up. Five of the students are Clio, Kora, Maia, Selene, and Electra. And the time destined for them to meet has now arrived.
