Yuki, an aspiring pilot, has been building an airplane with his friend Rotts in the hopes of being the second pilot to fly across the ocean, following in the footsteps of his idol, Schmidt (though he keeps these plans a secret from his mother, Miranda). So far, he has been rewarded with little success, with nearly twenty projects which, for varying reasons, have failed to get him where he wants to be. On this final flight, he finds that his mother stowed away on his plane, and is unable to fly high enough with the extra weight.
His reprimanding of his mother is interrupted, however, by the sight of a girl in a carriage being chased by several men. Yuki decides to get involved, and swoops down, inevitably crashing into the forest. He and Miranda fight to defend the girl, who they learn to be Alfina, a Communicator, one of those who speaks with the Guardian beasts. They, in light of what had just happened, offer to escort her to the temple at Arcriff, and become more and more involved in the events surrounding the disappearance of Alfina's brother, Emelious.
