Vega is serious, uptight and disciplined. In the beginning, he acts cold and mistrusting, but as he starts to warm up to people, he becomes much more protective and outspoken about his concern about others’ safety. Though he struggles to express it, he cares deeply for his friends and adoptive family. When romancing him, he initially is cold and expresses disbelief of the summoner’s feelings, but once he realizes that their feelings are genuine, he gets increasingly flustered and shy.
