第1話: Kal-El AlbusとArielが政治的な駆け引きの中でパイロットとしての訓練を受けるためにIslaに到着する。

Kal-El Albus and his younger sister, Ariel are preparing to enter Cadoque's High Aerial Division to train to become military pilots. The high school is located on the flying island known as Isla, where an alliance of three different nations (Kingdom of Qi, Balsteros Republic, and Bentares) hope to commandeer the island and learn more about the prophesied End of the Sky, which are rumored to reveal the secrets about the creation of their world by the god Saint Aldista. After being assigned to their dorms, Kal-El is taking a stroll on the island when he runs into a girl who is having trouble with her bike. He helps fix her bike and offers to take her back to her home in order to make her curfew. Along the way he learns the name of the girl, Claire Cruz, and they enjoy a breathtaking ride through the clouds until Kal-El accidentally crashes the bike. He shares a touching moment with her and they embrace. After he drops her off, he learns that she is of noble blood and he is not allowed to visit her, and he promises to meet her again.
