Korone is an android that was sent by the God Mahct to observe the new demon king.
Korone comes from a race of androids known as Liladans. She was sent by the government to monitor Sai Akuto 24/7.
As expected of an android, Korone doesn't show many emotions. Despite this, she does have a curiosity about most things and can display some human characteristics.
On one assignment, she is asked to try and provoke a sexual response from Sai and would constantly be teasing him. Even before this though Korone would be teasing Sai. She often tries to sleep in the same bed as Sai, much to his dismay. After his objections, she decides to sleep in his closet, where she can usually be seen watching him from a crack in the door.
