“ ...In a sea of fragments, if you ever disappoint me again, I will find the most miserable fragment and seal you there! You were miserable in the first place as a human, so it'll fit to send you to a really miserable world! „ ~ Lambdadelta

**Lady Lambdadelta**, also known as **The Witch of Certainty**, is a supporting antagonist in *Umineko: When They Cry*.

She used to be known as the most powerful witch in the universe, but was defeated by Bernkastel (whom she cares for but hides her feelings) in "another game". She is also known as the Witch of the Absolute and her "magic of certainty" allows her to kill anyone with an absolute result.

Her goal is to "trap" Bernkastel by making the game between Battler Ushiromiya and Beatrice last for eternity, thus forever involving Bernkastel in the game. She has lived for a thousand years. As a witch, she embodies the concept that "hard-workers are rewarded", and is very much respected even by human beings.

She doesn't flee from the human concept of a witch; hence, the power of hers, which is respected by human beings, is immeasurable. However, she is whimsical about whose efforts she will reward and, in many situations, the person who can please her more will be able to receive her smile. Her tremendous and swiftly fierce power makes any kind of witch surrender in a moment. However, she seems to be reckless and it was thoroughly read by Bernkastel.

Lambdadelta was voiced by Fuyuka Ōura, who also voiced the younger version of Miyo Takano from *Higurashi: When They Cry*.

## Appearance

Lambdadelta appears as a young girl with short blond hair. Her eyes were amber in the original novel but were switched to red for the anime and the PS3 adaptation. In the *Pachi-Slot* adaptation, her eyes were changed back to amber.

She wears a pink hat and dress and wears white-and-pink-striped stockings and shoes and bows of a darker shade of pink, almost red. She also wears black long gloves. The aforementioned bows are to be found in her hair, on her hat, on her dress and on her shoes. Some of them look a little bit like candies in shape. She also wears a pumpkin on her dress and a few green leaves. You can also see a row of small white pearls on the bottom part of her dress.

## Personality

She is playfully cruel. She loves Bernkastel very much, but chooses to hide it. In *Twilight of the Golden Witch* however, she openly expresses her love towards Bernkastel (albeit in a disturbing manner). In the Tea Party of Episode 8, it is implied that she shares a rivalry with Erika and this was further explored in her story mode with Chiester 410 in *Ougon Musou Kyoku CROSS*.

Standing on a higher plane of existence than humans and most witches, Lambdadelta doesn't have a great concept of them. That is why she uses them as mere pieces to play "games" against Bernkastel. From this viewpoint, she isn't particularly evil or wicked, just disregarding for human life which she considers ultimately unworthy.

## Role in the Games

### Legend of the Golden Witch

Lambdadelta's name is first mentioned in the ???. She is said to have been dethroned by Bernkastel alone in the past and "terrifying because of her cruelty".

### Turn of the Golden Witch

Lambda first appears in the ??? when Beatrice invites her to bet against Bern for her victory. She offers to help Beatrice while planning to take revenge on Bern for defeating her. After everyone else leaves, Lambda gives Battler a rousing speech and encourages him to save Rosa from Beatrice's torture and get back in the game.

### Banquet of the Golden Witch

Lambda gives EVA-Beatrice the recommendation needed for her to become the new Golden Witch and becomes her guardian. She attends the coronation ceremony.

In the Tea Party, Lambda shows annoyance that Bern's new piece Ange suddenly barged into the game board without warning. She later has a private talk with Beatrice and shows disdain that she isn't trying to win. Lambda reminds Beatrice that she became a witch in exchange for Lambda being allowed to use her perfect game board. If Beatrice falls short of victory then Lambda won't hesitate to take away her powers and throw her into the worst Fragment.

### Alliance of the Golden Witch

Lambda tells Ange in private that Bern has tricked her. Even if Ange were to stop Beato's game and set her family free, they won't return to her own future; they will return to a six-year-old Ange of a different Fragment, while this 18-year-old Ange is just a piece and will disappear when Beato's game ends. She also mentions Bern's promise of finding a Fragment where Ange was living happily with her family but couldn't find it, and claims that such a thing doesn't really exist. Lambda gives Ange the offer of becoming her piece instead, with the goal of keeping Beato's game running for as long as possible; if Ange accepts, she can stay with her brother forever and will be allowed to reveal her identity while Lambda traps Bern.

Beatrice decides to abandon the game, believing that Battler is unfit to fight her; neither side will be able to make a move, and so there is no winner or loser. Lambda tries to convince Battler to prove his qualifications, but he is unable to and soon disappears. Beato abandons the game board, and Bern leaves with Lambda chasing after her. Beato s later forced to return to the game board after intervention from Ange. Lambda shackles her to a chair, intent on keeping her there and watching over her for eternity until she wins the game. Battler also comes back thanks to Bern and manages to regain his spirit and qualifications, but Ange sacrifices herself for it and is torn apart. Lambda comments on the sad scene as it plays out.

In the ???, after Battler and Beato's big debate, Lambda and Bern lie in a bed and talk about the game. Lambda reveals she set the rule about Ange not giving her name, feeling that she and Battler would demolish Beato otherwise. They also mock Battler's theories, with Lambda correcting some of them in red truth. Bern and Lambda talk about how much they see Beato as their plaything and declare on their titles that Beato will lose for all eternity, and a miracle will certainly not occur.

### *End of the Golden Witch*

*In the place of Beato, who stepped down from the position of Game Master in the 4th game, Lambdadelta serves as the new Game Master in the 5th game. Therefore, it is expected that, while the 5th game may be quite similar to the previous game, there will be differences...*

Beato falls comatose, having given up on the game still, and Lambdadelta wants to take over as Game Master for her. Battler won't allow it since this game is supposed to be between him and Beato. Lambda promises that she'll arrange the game the same way Beatrice would, insisting that it will help him understand her better. Bern threatens Battler with making the Fragment of Ange being sad in the future a reality, and Battler reluctantly acknowledges the game but says Bern can substitute for him if Lambda's going to replace Beato. Lambda accepts this arrangement and begins the game with Bern.

When Battler rejoins the game, Lambda replays everything from the start to show him what's happened. She presses Battler for his theories regarding certain scenes such as Kinzo's appearance and discussion with others despite his death. As the game continues, Lambda gives red truths in response in Bern's blue.

When Bern explains how she solved the epitaph, Lambda transports her and Battler to the Sea of Fragments and gives him some training on how not to lose himself in it. When Bern's Battler substitute (Bern-Battler) solves the epitaph on the game board and finds the gold room, Lambda confirms in red that it's real. During the game, Lambda also acts as The Man From 19 Years Ago when calling Natsuhi on the phone.

Lambda arbitrates a 24:00 court session in the Court of Illusions to determine if Natsuhi is the culprit, with Erika and Bern acting as prosecutors and Battler as defense. A new rule is implemented where Humans who speak in red must have appropriate proof. The trial goes on and Natsuhi is eventually presumed guilty. Lambda awards victory to Bern and Erika when Piece-Beatrice demands to be convicted in place of Natsuhi. Lambda decides to punish her by having her meet the same fate of the other losers in Beatrice's past games and summons a horde of goats to tear her apart, remembering that their contract called for Beato to pay with her life if she failed to entertain her.

Before the goats can kill Piece-Beatrice, Dlanor stops them and announces that Battler still wants to debate. Battler gives a red truth saying Natsuhi is not the culprit, but Lambda invokes the previous rule and asks for proof. Battler is shut down, and Lambda plays along with Erika and Bern's theory that Natsuhi had an affair with Kinzo.

In the ???, Battler revives. Lambda resicnds the previous judgement and acknowledges Battler as the new Golden Witch and Endless Sorceror, reopening court so he can present his new evidence. Battler and Erika exchange blows, and when Battler successfully uses Gold Truth, Lambda understands that eh has truly understood Beato's game. Lambda declares the game to be even and passes her role of Game Master to Battler.

### Dawn of the Golden Witch

Lambda watches over Battler and Erika's game to ensure it runs smoothly. She shows a lot of awe and concern when both sides pull off some daring moves, especially with Erika not wanting to declare Detective's Authority at the start. Lambda, Bern, and Erika talk about the closed rooms in the first twilight. Lambda refuses to give red since she knows how the rooms are constructed and tells Bern to just trust her non-red observations. Later, Bern gets angry when Battler threatens to kick her out when he notices her trying to interfere with the game, and Lambda has to mediate between them.

Battler and Erika debate over Battler's corpse disappearing from his closed room. Lambda takes a look at what both sides have planned and comments that Battler's move looks horrible. She warns him not to cause a Logic Error, or else the game board will be blown away. Battler claims that he escaped the room despite the chain being set and sealed with tape, and Lambda concludes it's a valid move. The trick involves Battler switching places with Kyrie, who was also a first twilight "victim", however Dlanor announces that Kyrie cannot save Battler in red. Lambda is shocked that Dlanor can repeat this in red despite Battler not confirming it himself and says that Natsuhi could do it instead. She's denied in rd as well, and Lambda desperately says that the other first twilight victims could switch places with Battler, but Erika soon reveals they're all dead because she killed and decapitated them.

With the threat of a logic error looming, Lambda suggests to Battler that he either admit he messed up or reconstruct the closed room trick with new logic. Battler insists he can still solve the logic error and is sent to a guest room similar to the one his corpse was in. Until Battler can solve it, his mind will be trapped there forever. Lambda gives Battler some advice as a "survivor of hell" and says he should be able to keep going so long as he hates Erika and Bern. Battler is shocked at her demeanor, and Lambda starts to go crazy from remembering the logic error she herself went through a long time ago. She wishes the Game Master luck and leaves.

Chick Beato is still determined to save Battler from his logic error, and Lambda decides to give her advice as well. She tells her that the old Beatrice loved detective novels and closed room tricks, and formed her magic compendium out of those. Lambda assures Beatrice that the old her could solve this trick and disappears, expecting to meet her again soon.

Erika asks Lambda her about her logic error. She says that Bern went through an even worse one when she was still a piece. She references the Infinite Monkey Theorem to put into perspective just how long Bern struggled to escape her logic error, explaining why she's the way she is now. Erika responds with an observation that her own hell had to do with her ability to understand the truth, and that Lambda and Bern couldn't become Witches of Truth because they didn't have that. Lambda feels insulted but lets it slide as a reward for Erika's victory.

Erika plans to wed the comatose Battler and holds a wedding ceremony at the Cathedral. Bern and Lambda watch from a balcony and talk about Battler's closed room, with Lambda betting that Beato will revive and save Battler. Chiester 00 arrives later and secretly informs Lambda that Beatrice plans to storm the wedding. She tells the security detail to prepare for battle, wanting to liven things up.

Sure enough, Beatrice has revived and invades Battler and Erika's wedding, challenging the Witch of Truth to a duel. Erika accepts, and Lambda once again judges the game to ensure Beatrice and Erika's theories are legitimate.

### Requiem of the Golden Witch

Lambda briefly appears in the Tea Party, where Ange and Lion are disturbed from being forced to watch the apparent true events of The Rokkenjima Mass Murders, and tells them to just watch.

In the ???, Bern is made the Game Master of Beatrice's final game. Lambda witnesses her red declaration that she will not give this game a happy ending.

### Twilight of the Golden Witch

Lambda attends Battler's party and brings several gifts. She also brings Will and Lion with her, having saved them from death and made them her pieces. She enjoys the festivities when Bern arrives and reveals she's also the Game Master and has taken Ange away. Lambda agrees to act as an observer for Bernkastel's game between her, Battler and Beatrice in exchange for Ange's release at the end.

After Ange's release, she and EVA-Beatrice soon attack Rokkenjima and summon goats to devour the island. Lambda has no intention of helping and just sits around watching the chaos. Lion talks with Lambda about how Bern's convinced Ange to seek out the truth of Rokkenjima even if it means giving up her life, but Lambda still has no interest in helping. She thinks the ending for Ange's game is obvious, but Lion tells her to keep watching since they know it won't end as predicted. Seeing Lion's certain faith in Ange despite Lambda herself making a certain declaration to the contrary, she decides to stick around longer.

Battler's party retreats to the Golden Land, where Erika issues an ultimatum and tells them to surrender. As the group pretends to argue amongst themselves, Lambda disguises as a konpeitou and secretly speaks to Battler and Beato, telling them that Bern's group is in the City of Books. Featherine is holding an unveiling of Eva's diary there, but it's protected by a magical barrier that only those with invitations or witches of the Senate can pass through. The invitations are not the way to go however since they deactivated the second the party started.

The group asks Lambda to help since she's a witch of the Senate and has gotten inside, but she's unwilling to since crashing Featherine's party means getting the entire witch world as her enemy. Everyone convinces Lambda that it'll be thrilling, and she'll be able to stave off boredom for a while. Lambda gets angry since the only reason she's still here is to watch an interesting show, not to die horribly with everyone else. Lambda rants about how lame she is and how she lives in a completely different world than the others, plopping down in a chair and getting depressed. Battler apologizes and wants to prove his determination to save Ange.

Ange reunites with the group and wants to go back into the City of Books to retrieve the diary, realizing she still has her invitation. Ange asks Lambda to take her there since she can traverse the Sea of Fragments, and Battler asks to go instead since he exists outside the cat box while Ange needs to live into the future. The siblings argue and Lambda discovers that Ange actually had two invitations, meaning the both of them can go. Lambda agrees to take them to the City of Books, but after that she's going back to the sidelines.

Once they reach the City of Books, Lambda reminds Battler and Ange that they were protected by the rules of the game board earlier, but now that they've left they could be destroyed easily by Bern. Lambda decides she's still going to help because she wants Battler and Ange to show her a perfect happy ending. They sneak past guard cats and find out where the key to the diary is being held. Seeing that more cats are guarding the key and that it'll take time to unseal, Lambda proposes they send someone out as a sacrifice to distract Bern and everyone else. They play rock-paper-scissors to decide who will be that sacrifice, and Lambda purposefully loses. Battler and Ange are concerned that they can't return to the Golden Land if Lambda dies, and she hands them a Fragment that will send them back. Lambda doesn't mind fighting Bern anyway, as she has a score to settle. She turns the siblings into konpeitou, flicks them towards the key, and goes to find Bern.

Bern and Lambda banter and fight. Battler watches them and is unable to comprehend what is going on, describing them as creating and destroying universes. Featherine soon arrives and asks Bern how the ceremony preparations are going. Bern mocks Lambda, saying that any attack she does to her will require Featherine to respond in kind as per their contract. The Witch of Miracles asks where Battler is, but the Witch of Certainty ignores her and makes a small attack towards Bern. Featherine is confused and apologizes on behalf of Bern for anything they might have done to Lambda, giving her a warning not to interfere anymore. Lambda declares that everyone in the Golden Land is her miko and jokes around while focusing on Featherine's memory device, wanting to attack it and make her bug out.

Lambda attacks Featherine, but she stops the story. She's too drunk to write a proper fight scene, so she skips to the end and has Lambda slammed into a bookcase, falling to pieces. The story resumes. As Lambda wonders aloud what killed her, she gives Featherine a parting insult before falling into the City of Books' void. During Bern and Battler's battle later, Bern asks for help but Featherine says she's busy writing Lambda's final moments.

At the end, Featherine reveals that Lambda is still alive and has been moved to audience seating. In the Tea Party, Bern stitches Lambda back together amidst her complaints. Erika plays around with Lambda's limbs and then gives a status report about Dlanor and various other characters.

Lambda is restored and parts ways with Bern. They resolve to meet each other again when something else cries.

## Trivia

* She is very similar to Miyo Takano from Higurashi no Naku Koro ni in appearance, personality, and goals. This is likely simply a reference to Higurashi, because the events of Higurashi precede those of Umineko by three years (Higurashi taking place in 1983; Umineko in 1986), and she is said to have lived for a thousand years.
	+ Another similarity would be her name "Lambdadelta" (λδ) which represents 34 when using Greek numerals and "Miyo" (三四) can be translated as "three, four" in Japanese, strengthening their connection. In addition, Shannon's real name "Sayo" has a similar lecture to the compound 三四.
	+ The "game" she played with Bernkastel is strongly implied to be the battle that took place in the world of Higurashi with the battle between Rika and Takano being the purpose of the game. However, in both the sound novels and in an interview with Ryukishi07, not only did Lambdadelta not finish reading Higurashi by the time Bernkastel offered to spoil the ending, Ryukishi07 stated that her similarity to Takano was nothing more than a red herring used to throw off readers who read Higurashi first.
	+ In Umineko no Naku Koro ni Tsubasa, it is heavily implied however that she set the story of Higurashi in motion by granting with certainty Takano's wish to become a god which would explain why Bernkastel always says that she was trapped in a witch's game which was most likely Lambdadelta's certainty.
	+ Also in Umineko No Naku Koro Ni Tsubasa it shows a scene that is implied to be Lambdadelta granting Yasu's wish to become a witch. This is even more heavily implied when the game says that a boy is also called a witch and that asking to be a witch implies nothing about this "person's" gender, suggesting that the person is Yasu and the writer still has not disclosed what Yasu's gender is.
* She shares the same distinctive laugh as Satoko Houjou from *Higurashi no Naku Koro Ni*, and also as the same penchant for making traps.
	+ Lambdadelta's link to Satoko Houjou is strengthened in Twilight of the Golden Witch, when the pie riddle that stumped Satoko in Higurashi was said by Bernkastel to have been failed by Lambdadelta.
