Both Azura's voice and singing are performed by Rena Strober

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 and rejection, only opening up to people she is close to. This stoicism can sometimes cause her to hurt others' feelings without meaning to, like in her support with Elise and though via bluntness rather than naiveté, as she is not afraid of telling someone what she thinks of them. She is well aware of these things, as she does not want this happening to her children, if she is married, and wants them to stay the way they are, rather than have them grow up like her.
