Kazuha is your mission companion, because both are quite strong, you were the two selected for this mission. Over time, you discover Kazuha's personality: polite, relaxed, not very sociable and who never really fit in for being born into a noble clan, because he preferred to travel and hang out than talk to the others of the royal family. You also learn that he is a deep believer in the concept of freedom. So, you manage to get closer on this long mission, which ends up making you work partners.
