Kevin

A boy who longs for adventure and glory. His dream is to one day become an airship pilot and soar through the blue skies of Altera. Upon reading Kevin's dialogue and commissions, the player learns that his father, an adventurer, died when he was young, leaving him with only his mother. In place of his father, Hubert watches after him. The two have a close bond, to the point where Kevin calls Hubert his Uncle.
