Koroku Inumura

The story revolves around Charles Karino, a Levamme kingdom mercenary aerial pilot who mans the twin-seater reconnaissance seaplane Santa Cruz. One day, he receives a preposterous assignment: to fly solo over 12,000 kilometers of enemy waters to protect a girl named Fana del Moral. Fana happens to be the next in line to the kingdom's throne and a girl possessing beauty "equal to 5,000 beams of light."
