Toaru Hikuushi e no Tsuioku

The war between the Levamme Empire and the Amatsukami Imperium has been raging for years. In the midst of this struggle, the prince of the Levamme Empire declares his love for Juana del Moral and vows to end the war in one year, as part of his marriage proposal. When the Amatsukami catch wind of this, they assault the del Moral residence, targeting Juana's life. As a last ditch effort to bring the prince his bride, the San Maltilia Airforce hires a mercenary of mixed blood—a bestado—to fly Juana to the Levamme capital in secret. The pilot, Charles, accepts the mission...but traversing an ocean alone, into enemy territory, proves a much more dangerous ordeal than anyone could have anticipated. (Source: NIS America)As a beautiful daughter of the noble family del Moral, Fana was proposed to by Prince Carlo, who is the crown prince of their country Levamme. However, since Levamme is at war with Amatsuvian, the marriage had to wait until the war ends. Meanwhile, as a bestado, the lowest caste in Levamme, Karino Charles had always dreamed of flying and eventually became the ace pilot of the San Maltilia air force. Although he was often mistreated, a glorious chance came about when the Amatsuvian bombarded del Moral's home in order to get rid of the future empress. Charles was then entrusted with the top secret mission of delivering the princess to the prince of Levamme.
