As an experienced gambler, Celestia appears collected, cold, cunning and very selfish by nature. She possesses the ability to manipulate others to do her bidding and can lie with a straight face. She even has a habit of ranking men between Rank A and Rank F, supposedly to test who is worthy of being one of her servants. She uses polite language, but her short-temperedness surfaces when something fails to go her way. She is looking forward to summer with her acquaintances.
