Korone

Korone (ころね) is a Liradan (リラダンRiradan), a race of androids sent by the government to observe Akuto Sai 24/7.

Appearance
Korone has green green hair and dark green eyes. She typically wears the female uniform of the academy with the addition of a light pink handbag with a darker pink strap on her right side, which contains numerous firearms and other items, a sort of hammerspace. She wears white panties with green horizontal stripes and a rabbit's tail that can be pulled on her lower back, which causes her to deactivate.

Personality
Korone 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 perverted things in front of him to get a response. She sleeps in a small storage closet in Akuto's dorm room, much to Akuto's dismay due to Korone watching him from the closet during their first few days together. Despite her emotionless demeanor, Korone seems to have feelings for Akuto, displaying a visible emotion of sadness when Akuto scolds her after being ordered by the higher-ups to seduce him.

Abilites
Korone has the ability to read other people's emotions, and can detect an individual's presence based on mana emitted by that person's body. She, like all Liradans, can be temporarily deactivated by pulling a switch resembling an animal's tail (in her case, a rabbit's) located on her lower back. She will reactivate after the tail is pulled again, and is otherwise unconscious while she is deactivated. Being an android, she is unable to use mana. Instead she is able to uses weapons and gadgets.
 * Cannon: She is usally seen using a large cannon in combat.
 * Radar: She is a able to use a radar to locate/detect an individual's presence based on mana emitted by that person's body.

Manga
She is also married to Akuto along with Kena Soga, Junko Hattori, Fujiko Eto, and Lily Shiraishi in Volume 5 Chapter 50.
