Azura

Due to the heavy rejection, bullying, and discrimination she faced in her time as a princess in Nohr, and the distrust from some of the people in Hoshido due to said Nohrian ties, Azura developed a reserved and stoic personality, sprouting from her fear of provocation, persecution, and rejection, only opening up to people she is close to. Azura feels guilty that she received the love from the Hoshidan people and the royal siblings that rightfully belonged to Corrin. (I don't own this character, this character is owned by Nintendo.)
