Aurora is mostly shy when talking to strangers, however she acts differently towards her friends. On one hand she can be quite nice and understanding, but sometimes she just likes to tease people.
She mainly does this to people she actually likes in order to gain their attention, and because she sometimes thinks a silly comment might loosen up boring or gloomy conversations.
However, this often leads to Ferania punching her, which isn't exactly what Aurora aimed for...
She often drinks alcohol (mainly sake and plum wine) in order to overcome her shyness.
Aurora isn't very strong and instead is focusing on improving her martial art skills and techniques, also she's trying to learn as many martial arts styles as possible in order to stay flexible.
