Celestia Ludenberg

Celestia Ludenberg is one of the characters in Dangan Ronpa. Her real name is Taeko Yasuhiro.

Personality
As one would expect from an experienced gambler, Celes is collected and cunning. Titled as ‘Queen of Liars,’ she has no difficulties telling lies with a straight face and manipulates others into her bidding. She evidently makes 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 short-tempered nature that surfaces if something doesn’t go as well as she expects to be.

Pre-Despair Incident
Very little is known about Celestia's life before being trapped in the school with her fellow classmates. However from conversations with Naegi the player can find out that Celestia has been gambling for most of her life and hasn't heard the term 'lose' for a long time. Celestia also reveals that she used to go to a cafe where the owner looked a little like Yamada and that she always used to have milk tea but prefers Royal milk tea.

High School Life of Mutual Killing
Celestia like the other students wakes up to find herself trapped in the school grounds much to her annoyance. After finding out that they are trapped in the school Celestia is quick to adapt to the conditions and simply says that it's the only way to survive and those who don't will die.

When Monobear gives the students 'motives' through the use of footage on a CD, Celestia was horrified at what she saw but refused to tell anyone what it was. It's never revealed what Celestia saw on her CD. After the deaths of Maizuno and Junko, Celestia helps the other students solve the case.

Celestia played a key part in chapter 2 due to her seeing Chihiro in the storage room at 10pm. Celestia points out that the sleeve of Chirhiro's sweatshirt was haging out of the bag she was carrying, Chihiro thanked Celestia and ran off in a hurry. Celestia did not know that this would be the last time she would see Chihiro alive. These events helped the other students work out who Chihiro's murderer was.

After weeks of staying in the school Celestia finally decided that she has had enough and started to plan a murder and how to get away with it. The first thing she did was take and hide Alter Ego in order to create confusion and to upset Yamada and Ishimura, later that day Celestia confronted Yamada and told him that Ishimura has taken Alter Ego and that he was planning on killing him. Yamada believed the lie and the two of them hatched a plan to kill Ishimura and escape the school by graduating. The two of them framed Yasuhiro Hagakure by knocking him out and stuffing him into a robot outfit. After Ishimura's death Celestia then organised Yamada's 'death' and managed to trick the others into looking for a suspicious person in a robot suit. After Yamada's body 'disapears', Celestia met up with Yamada who had moved himself and Ishimura's body to the art room, much to Yamada's horror Celestia turned on him and killed him.

During the trial Celestia pushed for the others to declare Hagakure as the culprit however Togami, Naegi and Kirigiri saw through her lies and managed to prove Hagakure's innocense. She became more desperate then and after being pushed by the three of them she finally broke and 'lost'. Celestia admits to her crimes but is content with her iminant death saying that she wants to go out 'gracefully'. She gives Kirigiri the key to the locker Alter Ego is located in and bids her fellow classmates farewell before being dragged by Monobear to her execution.

Execution
Celestia is tied to a stake and begins to burn. Celestia is content with this and accepts her death happily until a firetruck crashes into her, killing her instantly.
