Korone is a Liladan, a race of androids, sent by the government to observe Akuto 24/7. She is usually emotionless and stolid, but occasionally curious when it comes to certain things. However, she does display human characteristics on occasion; particularly, she enjoys teasing Akuto, often doing ecchi things in front of him. She sleeps in a small storage closet in Akuto's dorm and has numerous firearms and other items stored inside her handbag, a sort of hammerspace. Korone has the ability to read other people's emotions and can detect an individual's mana levels. She, like all Liladans, can be temporarily deactivated by pulling a switch resembling a rabbit's tail located on her lower back. She starts having feelings for Sai.
