She is not good with stories of the occult, but loves to talk about it a lot. She's had a sixth sense for it even since she was a child.

She is fond of saying "Let's eat a banana".

She is a martial arts expert, with dozens of martial arts skills mastered. However, she is a strict and merciless older sister to her younger brother. Like a nagging grandmother, she worries for the brother but easily goes overboard into "severe scolding mode", even using force. She always justifies herself by saying "It's training!"
