Miranda is cute and polite, in contrast to her family, which is a tyrannical and genocidal undersea monarchy. Despite her cuteness, Miranda was raised believing things like murder and genocide are fine, which show in her treatment of peasants and serfs, and using execution and intimidation to keep others under control.
She is fairly innocent, not knowing much about sex and believing it should just be used to determine who is a good suitor. She is very driven to find a prince, resorting to things like poison apples, or dating sites.
She owns many serfs, having one for practically everything she does, including eating. How she stays alive is a mystery, but in a lunchtime event, the player speculates they feed her through an IV while she sleeps.
She enjoys princess movies, tyrannical regimes, cat videos, complicated silverware, and emojis. Her love for silverware.
