–Celestia Ludenburg, Danganronpa: Trigger Happy Havoc
Celestia Ludenberg (セレスティア・ルーデンベルク Seresutia Rūdenberuku), real name Taeko Yasuhiro (安広 多恵子 Yasuhiro Taeko), is one of the characters featured in Danganronpa: Trigger Happy Havoc and a participant in the Killing School Life.
Celestia enrolled in Hope's Peak Academy's Class 78th and has the title Ultimate Gambler (超高校級の「ギャンブラー」chō kōkō kyū no “gyanburā.” lit. Super High School Level Gambler) She was renowned for managing to rob any who challenged her of all their money. Due to her nature, she was given the title “Queen of Liars”.
In Chapter 3, Celestia was revealed to be the culprit of the third murder case, as part of which she has manipulated Hifumi Yamada into killing Kiyotaka Ishimaru and then murdered him herself, and was thereupon executed by Monokuma.
Celestia played a minor role in Danganronpa 3: The End of Hope's Peak Academy.
Celestia is around 19 years old, though she believed herself to be 17 in Danganronpa because of the memory loss. 
She has a slim figure and pale skin. She has black hair (in the video game it is shown as dark, deep blue) in two large twin-drill pigtails (which are actually just clip-ons as mentioned in the art book), red eyes, gold earrings, and black nail polish.
Celestia wears a gothic lolita-style outfit, consisting of a white blouse with a Peter-Pan collar, a black jacket that includes white ribbon lacing down the sleeves, fastened by a simple ribbon across her chest to show her red tie with a butterfly pattern on it and the waist of her skirt, which is many-tiered and features white lace.
Celestia wears knee-high stockings trimmed in ladder lace, red mary janes with a thick heel, a white lace headpiece and a silver, almost weapon-like ring (reminiscent of a certain ring by Vivienne Westwood) on her index finger.
An experienced gambler, Celestia appears collected, cold and cunning by nature. She possesses the ability to manipulate others into her bidding and can lie with a straight face. She is shown to be fairly intelligent, referencing several aspects of game theory such as Prisoner's Dilemma or Zero Sum Game and her manipulative and coercion skills are shown in Chapter 3, being able to deceive the majority of the students, including Byakuya up until the Trial. Her intelligence is also shown in previous cases in which she, alongside Kyoko, Byakuya and Makoto are the ones to bring up crucial points and is also capable of keeping up with Byakuya and Kyoko's train of thoughts during the trials as well.
Celestia is a very ambitious person, as she declared that she will do anything it takes to win, and is ready to go as far as murdering someone or manipulating others in cold blood. She is extremely selfish and values her life over the lives of others, stating she has no problem sacrificing others in order to save herself. She also has a lot of pride, refusing to surrender no matter how far into the corner she's pushed, as long as the chance for victory remains. However, if it's known that she's about to lose with no way out, she accepts it calmly.
Celestia believes in adaptability to be the key to survival, rather than strength or intellect, and she acts upon this by setting up measures such as the voluntarily imposed night-time curfew to protect the other students, as well as herself, from potential killers during the Killing School Life. She often reminds others to obey the curfew and is often annoyed when people such as Byakuya Togami, violate the curfew. After the death of Chihiro Fujisaki, she coldly remarks that people who disobey the rules pay the price. She also tells the other students to endure the Killing School Life in order to survive, such as complementing unlocked rooms after the students survive the Class Trial stating that they will enrich life. In reality she was lying and after being voted guilty, she openly stated she couldn't stand living in the school.
Celestia speaks softly and smiles often, but in a way that tends to creep out everyone around her. She usually uses polite language whenever she talks to the others, but her short-temperedness surfaces when something fails to go as well as she expects it to, such as when Hifumi fails to make her royal milk tea as she likes it. Another example is during the third Class Trial when she pinned as the blackened, Celestia quickly lost her composure after being accused of murder. She shouted and denied accusations towards her with unusually rude mannerism, often using vulgar language.
She aspires to be like European royalty, such as wearing lolita clothing, using an old English accent (English localization only) and making her fake name sound like European royalty. Her other mannerisms and strict, spoiled nature emphasizes this. She also seems to have quite a lot of made-up stories about her life as Celestia Ludenberg. Her goal in life is to live in a big fancy European castle with handsome man servants dressed as vampires. The reason for all of this is a bit unclear, but she appears to hate her real self, as she dislikes ordinary and common things and considers her real identity and name ones of "a loser".
As the Queen of Liars, Celestia claimed that she can even fool her own emotions, but this doesn't seem to be entirely the case. She appears to lack empathy and claims that she feels no guilt for bad things she's done, though considering her status as a consummate liar, it's possible that she felt at least something.
Skills and Abilities
At young age, she became a gambler and won countless games, even ones at the stake of her own life, but was able to win regardless. She states during a game of King of Liars, she spilt tea on her favorite dress and she had to end the game quickly to take it to the cleaners. She once even managed to accumulate over ten million dollars. She also won a Shogi tournament despite not really knowing how to play the game. Though her poker-face helped, she claims that the secret to her success is the luck she was born with. She was renowned for managing to rob any who challenged her of all their money and she gained the title "Queen of Liars". She kept earning money for her main goal in life - to live out the rest of her days in luxury in a big fancy European castle with handsome man servants dressed as vampires.
Queen of Liars
She was renowned for managing to rob any who challenged her of all their money. She was rather proud of her ability to tell lies, as shown how she can manipulate someone on her own gain through lying.
Prior to the Tragedy
Celestia's real identity is Taeko Yasuhiro. Little is known about her past, but it's implied that she was a completely ordinary and un-special person (at least in her own opinion) and she created the fabricated persona of 'Celestia Ludenberg' as a result.
Celestia's fake backstory explains how her father is of French nobility and that her mother is a musician from Germany. She also states she was born in the Tochigi prefecture.
The most important thing for her, along with her dream, was her spoiled cat Grand Bois Chéri Ludenberg. This implies that she didn't care for any people, including possible blood relatives.
Celestia also used to visit a cafe (with an owner that somewhat resembled Hifumi), where she would enjoy her preferred royal milk tea.
Celestia attended Hope's Peak Academy's Class 78th as the Ultimate Gambler.
After agreeing with Jin Kirigiri's proposal about sheltering the Class 78th in the old school building during the Tragedy, Celestia is seen casually drinking tea at a small table while her classmates work to seal up the school.
During the Tragedy
During the Tragedy, Jin, the Headmaster of the Academy, planned to seal the school building and let the students live forever inside the Academy in order to protect them from the destruction. His plan was agreed by the class, and they sealed the building together and lived peacefully inside it for a year without knowing that the Ultimate Despair members were already in their midst.
Junko Enoshima took away the Class 78th school memories so they could participate in the Killing School Life.
Prologue - Welcome to Despair
Much like the other students, Celestia awakens to find herself trapped inside the school grounds, to her annoyance. She appears to adapt quickly to the new conditions, claiming that it is the only way to survive, and suggests the others do the same. She was also the person who suggest the students to not went out from their room at Night Time, to prevent a murder.
Chapter 1 - To Survive
When Monokuma introduces the first “motive” to each of the students through individualized footage on CDs, Celestia is horrified at what her CD shows (but refuses to say what exactly she saw, which is never revealed). She later appears in the gym after Sayaka Maizono's corpse found by Makoto Naegi who falls unconscious. After witnessing the death of Mukuro Ikusaba (disguised as Junko), she looks at the Monokuma File and notices Sayaka's murder was in Makoto's room, creating near unanimous suspicion on him.
During the class trial, Celestia initially believed it was Makoto, and when Kyoko Kirigiri reveals that Sayaka sent a note to the killer to meet up in her room, she initially didn't believe it since going to Sayaka's room would be where Makoto was, however Makoto explained this with the nameplate swap, as it meant that the killer went to the Makoto's room which had the Sayaka nameplate on it, where Sayaka was.
When it is discovered that Sayaka tried to kill the culprit, Celestia realizes that Sayaka was using Makoto and explained that it took care of the nameplate issue, as it was used as a part of Sayaka's plan to kill the culprit in Makoto's room to frame him.
Later it is found out that Leon Kuwata killed Sayaka after she tried to attack him, though he claims self-defense, Celestia disagrees, stating that since he got his tools from his own room, he had plenty of chances to end it there.
Chapter 2 - Boy's Life of Despair
Makoto first encountered Celestia and everyone in the cafeteria; using her poker face, she was able to manipulate Hifumi to make a cup of Royal milk tea, only for her to lose her temper and shout at Hifumi when he failed at first.
Celestia plays a key part in Chapter 2, having encountered Chihiro in the storage room prior the latter's death. During this encounter, Celestia notices Chihiro's blue jersey partially hanging out from his bag, which he then stuffs back inside before going off in a hurry. This later proves to be a major factor in figuring out Mondo Owada, as the culprit.
Chapter 3 - A Next Generation Legend!
After Mondo's execution, Celestia is among the students who witness Monokuma present a ton of cash (10 million dollars) for whoever “graduates” from the academy. Succumbed to her own greed, Celestia plans to commit a murder herself so she can get the cash to escape the nightmare while ignoring her own comrade's survival.
To initiate her plan, Celestia takes Alter Ego, the AI developed by Chihiro before his death, and hides it to cause confusion and upset both Hifumi and Taka. Using their conflict for Alter Ego as her first step of her plan, Celestia enlists Hifumi as her accomplice (and tells him that she will act as his) by lying. She tells him that Taka made her steal Alter Ego by forcing his way into her room, threatening her, abusing her and taking photos to blackmail her with. She then furthers her own lie by telling him that Taka plans to kill Hifumi so he can have alter ego all to himself.
Hifumi believes Celestia and the two begin to conspire. They frame Yasuhiro Hagakure by knocking him out and stuffing him into a robot suit. Celestia organizes Hifumi's “death” after Taka is killed, managing to trick the others into looking for the suspicious person wearing a robot suit. After Hifumi relocates himself and Taka's body to the Art Room, Celestia turns against him and kills him, as she planned to do from the beginning.
During the class trial, Celestia urges the students to declare Hiro (Hifumi's last clue before his real death) as the culprit to both murder since the robot costume matched his height. However, Byakuya, Makoto, and Kyoko see past her lies and manage to prove Hiro's innocence.
Even with evidence having her cornered, Celestia refuses to admit (changes her polite personality into her unusual rude mannerism), and would repeatedly deny Makoto's question over her real name and kept claiming that Hiro is the culprit of the third trial, since she never revealed her real name since their first encounter.
In the end however, Celestia's last stand is proven futile as Makoto mentions her e-Handbook (real name displayed in every student's handbook) and would let her guard down and that evidence alone would lead to her downfall.
As she finally went to the gallows and Monokuma reveals her real name as Taeko Yasuhiro, Celestia finally told them and admits to her crimes before facing her execution, stating that she wants to go out “gracefully”. Aoi Asahina and Hiro who still don't know why Celestia would commit such a murder even though she was the one who tell the groups to 'adapt' with their environment.
Celestia then declares she is the one who most wanted to get out from the Academy. She told to everyone that she had a dream to live in an European castle and surrounded by handsome butlers for the rest of her life, but her dream will be ruined if she is forced to stay at the Academy forever. She also believed that after her death she will reincarnate as Marie Antoinette, Hiro mentions that she would just be executed again.
Celestia gives Kyoko the key to the locker Alter Ego is stashed in, bidding her classmates farewell and having Monokuma drag her off to her execution afterwards.
Celestia is seen alongside her deceased classmates in Makoto's hallucination. Celestia is later seen on fire when all of the deceased morph into how they looked when they died.
Grand Bois Chéri Ludenberg is Celestia's pet cat. She enjoyed his company and pampered him, and most likely she was planning on having him with her in her dream mansion.
Grand Bois Chéri was also Celestia's Captive and closer to her than anyone else. This implies that she didn't care for any people, including possible blood relatives.
Hifumi and Celestia's relationship consists primarily of her bossing him around. A prime example of this is when Hifumi makes Celestia tea, only for her to dash the cup to the ground, claiming that she only drinks a certain milk tea. This is later taken to greater extents as Celestia manipulates him into murdering Taka with the premise of escaping the academy alongside her, using a photograph of Alter Ego in Taka's room to provoke his anger; however, she subsequently backstabs him by murdering him in a similar fashion, then framing Hiro.
Shortly after Celestia and Hifumi's deaths, the survivors found a picture of the two and Sayaka. In it, Celestia seems to be angry with Hifumi, indicating that their relationship was the same during their time in high school.
Celestia seemed to be rather fond of Makoto and she was curious to see if his luck as the Ultimate Lucky Student could beat her luck as the Ultimate Gambler. When she does her personal ranking, she ranked him with C-rank, which is higher than any of her classmates. While Makoto considers Celestia a friend, he is intimidated by her luck and that she would have a person assassinated if she found them boring.
During the Killing School Life, Celestia planned to frame Hiro in her murder case scene. The reason why is because Hiro was one of the stupidest students in Celestia's mind until the point that she pitied Hiro's parents for having a son such as Hiro.

Creation and development
Celestia is a goth-loli character and has been consistently goth-loli since the planning stages.
The character designer, Rui Komatsuzaki, has a personal interest in goth-loli fashion, so the design advanced to its final stage without much deviation. However, Celestia was a bother to draw due to the goth-loli style's many ornaments and embellishments, as well as her clip-on twin tails.
Celestia was made to look more doll-like than the other characters, so her skin's saturation lowered considerably. She is noted to be relatively tall because she's of average height but wears high heels.
