Celestia Ludenberg

Personality
As one would expect from an experienced gambler, Celes is calm and collected. Titled as 'Queen of Liars,' she has no difficulties in telling lies with a straight face and manipulates others into her bidding. She evidently makes her use of her talent when she tricks Yamada into killing Ishimaru and deceives other students at most part of Chapter 3. Celes is shown to be fairly intelligent, referencing several aspects of game theory, such as Prisoner's Dilemma or Zero Sum Game in her speech. She also has a very short temper that surfaces if something doesn't go well with her expectations.
