- "Six of us are... dead. Counting myself, there are only three left. They were killed. I... I guess you could say I killed them... No...no, that's not quite right. Not just them. Not just these six... All of them... All six billion... Soon, I will have killed six billion people..."
- — Diana to the Operator, about the dire situation at the facility
Diana is one of the three main protagonists of Zero Escape: Zero Time Dilemma, the other two being Carlos and Q. Although somewhat emotionally timid, Diana is a cheerful, pacifistic, and gentle nurse. Abducted against her will, she is a player in the Decision Game and the leader of Team D, which also consists of Phi and Sigma Klim.
In the timeline leading to Virtue's Last Reward, on December 31st, 2028, a suicide virus called Radical-6 was released. After the pandemic and Antimatter Plant Explosions, 6 billion people humans died, as well as millions of animals. Diana holds herself responsible for the deaths of these 6 billion and almost the entire human race. Later in this timeline, Diana was the basis for the creation of the GAULEM known as Luna for the Nonary Game: Ambidex Edition.
Diana has slightly droopy eyes that are two different shades of blue, a blue small lined pattern around her pupils, orange eyelashes, faint freckles around her nose, and a wide mouth. Her eyebrows are thicker than Luna's. She has orange middle parted hair falling just past her shoulders; part of her hair is kept up in a waterfall braid around her head, decorated with purple daisy flower clips on the sides and a silver barrette in the back where the braids connect. She also has small side bangs in front, which are shorter than the rest of her hair.
She wears a blue collared shirt with a red boat-neck sweater on top of it. The sweater's cuffs have a yellow ring around the start of them, and the blue shirt cuffs are peeking beneath that. She has a long brown skirt with cream laced edges. The pattern of the cuts on the skirt suggest that it is a denim skirt. A thin blue belt holds it around her waist. She has red tights underneath and white-with-blue-stripes flats. The shoes have little blue bows on them. Like the other players, she has a black bracelet on her left wrist.
Diana's necklace is a caged bluebird, which also functions as a music box that plays "Blue Bird Lamentation", a reference to the caged bluebird's loneliness and sorrow. However, she doesn't actually wear it, only showing it to Sigma once in the Healing Room.
The necklace was inspired by Maurice Meaterlinck's play The Blue Bird. In Maeterlinck's original story, it doesn't end with Tytyl and Mytyl waking up. When Tytyl and Mytyl try to feed the bird, it leaves the cage and flies away. It reminds Diana of the following lesson: "Happiness is closer than you think."
Diana is cheerful, kind, and gentle. Diana loves peace, just wants everyone to get along, and hates fighting and violence. Phi comments that Diana is too nice, and Diana says people tell her that it's a fault. During her time as the D-Team leader, she develops a close bond with both Phi and Sigma and tries her best to ensure their survival. She also seems to care and have empathy for animals; in D-END: 2, when Sigma discusses how long their food will last, Diana says, "You remembered to include Gab, right?" and during the true ending, she comments how glad she is that Gab is safe. As the template for Luna in both appearance and personality, Diana is pacifistic and wishes to escape the facility with everyone alive. However, this may come at a fault; her strong desire to save Phi is the reason the Radical-6 apocalypse occurred.
Diana seems to possess an inquisitive and curious side - she is someone who wants to learn more about the world and everything around her. She frequently dishes out questions and has a will to find the truth.
There are subtle differences between Diana and Luna; the former is a human and the latter is a robot. Diana is more "flawed", and she is seen arguing with Sigma, lashing out at him, using sarcasm, slapping his face once, and even insulting him at one point saying he's a "coward with no balls", something Luna would likely not do.
Diana seems to almost always have an uncomfortable, scared, nervous, anxious or worried expression - it is unknown if this comes naturally, or if it is the result of having the lives of the entire human race, as well as her own, as a burden on her shoulders. It also may be a result of the stress and trauma she was dealing with due to her ex-husband.
Diana exhibits some borderline suicidal traits, or possibly can't deal with guilt. If Diana kills Sigma in the Trash Disposal Room, she picks up the revolver and shoots herself in the head. Also, after killing six other players in an acid shower room, she refuses to leave and traps herself in the shelter. Zero then appears and suggests she has multiple personalities, or that she faked having multiple personalities, so she wouldn't have to deal with her guilt for killing six people, but doesn't go into detail. Phi wonders if Diana has "alien hand syndrome".
Due to being a playable character, some of Diana's actions can be determined by the player, leaving to varying interpretations of who she is.
Diana also expresses some disdain for social media, saying she became sick of the urge to constantly check online feeds, and how many people try to document every waking moment of their life online, or try to make it seem like they have "perfect" lives.
Virtue's Last Reward
Sigma, Tenmyouji, and Clover found a blue memory card in the Pressure Exchange Chamber's safe. They decide to look at what is stored on it by inserting it into a monitor in the Infirmary. A recorded conversation starts, taking place on December 31, 2028 at the Mars Mission Test Site. An operator is heard talking to the participants inside of the facility. He realizes that his feed has been hacked. The situation has gone awry in the facility, with Diana reporting that the Radical-6 virus escaped and eerily says that she didn't kill just six people, but six billion.
Sometime before the events of Zero Time Dilemma, Diana was married. Her husband was once serious and kind. However, once married, he began abusing alcohol, and physically abusing Diana by beating her, for no apparent reason. He laughed while kicking and punching Diana.
Fed up with her husband's cruelty, Diana divorced him. However, this did not stop her ex-husband from harassing her and making constant attempts at contacting her for money or sex. He would show up at her work at a local hospital where she was a nurse. One time, he entered the hospital cafeteria, flipped a table, and started screaming at her. He would lash out and turn violent, beating her until she was black-and-blue in bruises, but every encounter ended with him weeping, proclaiming that he loved her so much. His pain called out to Diana, and Diana found herself caving into him.
Diana eventually became tired of his stalking. The head nurse, Rebecca, recommended that she participate in the Mars Mission Test Site (Dcom) experiment in Nevada in December 2028. Seeing the week long seclusion as a means to stay away from her ex-husband, Diana willingly became a participant.
During her time there, she was approached by a young woman among the participants, Phi. Out of nowhere, Phi asked if she could hug her, which she obliged, thinking that Phi was experiencing stress from the experiment. Something about Diana's scent seemed familiar to Phi, but Diana was just simply happy to help Phi calm herself. Near the end of the experiment, Diana was captured and forced to participate in the Decision Game by Zero II.
Zero Time Dilemma
Diana is a participant of the Decision Game. She leads Team D, which also includes Sigma and Phi. As such, Diana handles certain decisions and responsibilities that affect Sigma's and Phi's fates. Her team is trapped in Ward D of the Underground Shelter.
In the Trash Disposal Room, she may choose to shoot Sigma with a revolver that has a 50% chance of killing him, or not shoot and incinerate Phi.
In one decision, Diana pulls the trigger and it fires off one of the loaded bullets, killing Sigma. Phi is released from the incinerator and sees Sigma dead and Diana weeping. Phi blames Diana for killing Sigma and, filled with grief, Diana takes the revolver from its pedestal and shoots herself in the head, hoping she will reunite with Sigma soon.
D-END: 1 (Circle Of Fate/A Rabbit In Your Future)
This is the timeline that leads to Virtue's Last Reward.
Diana escapes the Underground Shelter and calls the operator. Diana insists on securing Phi's survival, which leads to the Radical-6 pandemic.
In the Post-Apocalypse files, it is revealed Diana eventually moved in with Sigma on the Moon about 5 months after the end of the Decision Game in May 2029. This means she somehow survived the Radical-6 outbreak and the Antimatter Plant Explosions.
Together she lived with the Sigma consciousness that returned from the events of Virtue's Last Reward for about three years. During that time, Sigma and Diana fell in love with each other. She also helped Sigma with researching genetics, quantum mechanics, cosmology, biochemistry, artificial intelligence, etc. Despite having access to Medical Pods, Diana's health quickly began to deteriorate due to the low gravity of the Moon and she developed a circulatory illness. Diana passed away peacefully in Sigma's cybernetic arms as she dreamed of another possible future where she lived out a full, happy life with Sigma. Sigma kept her blue bird music box and would eventually give it to a lonely Luna.
Years (decades) later, Sigma's son/clone Kyle Klim wanted a mother. Prior to this, Sigma already constructed a GAULEM, Luna, for the purpose of the AB Project. Sigma asked her to fulfill Kyle's request, despite it not being his original intention for Luna. While not a perfect copy, Luna closely resembled Diana in appearance and personality and even had the same bluebird music box necklace that Diana once possessed.
D-END: 2 (The Hope Of Two/A Silver Lining)
Should Diana choose not to fire the gun at Sigma, Phi is incinerated as a penalty for not pulling the trigger. The two despair over the death of Phi and the only memento left of her is her brooch which managed to survive the incineration. However, they are not given long to mourn as they are knocked out by their bracelets.
After completing the Transporter Room and learning about the transporter, Diana and Sigma find themselves stuck in the Underground Shelter since Akane Kurashiki had used the X-Door, thus preventing them from leaving themselves. With no way out, Diana and Sigma settle down and wait in hope that Akane will eventually return with help, with little over ten months' worth of food available.
At first, Diana takes things well, finding her time with Sigma to be pleasant and peaceful, free from the worries of the outside world. However, a month into their lock-in, Diana's stress begins to rise, believing that Akane had abandoned them. Sigma reveals that he knows about her past with her abusive ex-husband.
Diana's mental health continues to worsen and she eventually starts drinking heavily and lashes out at Sigma for knowing things he should not and being nonchalant with their predicament, and she wants to be left alone. When Sigma forcefully takes her alcohol, she is annoyed and tries to grab it back, causing the bottle to slip and spill onto the floor. Diana attempts to lick it, causing Sigma to shove her away, and she claims she was merely joking. Diana asks for sex. When Sigma remains silent, she asks Sigma to kill her, prompting Sigma to slap her face. Depressed, Diana returns to the Transporter Room to cry by herself. Sigma eventually comes to her and finally opens up to her, saying that he was afraid of losing her, like he did in a different history, or like the blue bird in the cage represented in her necklace.
Diana and Sigma forgive each other and confirm their love by sleeping together in the Transport input pod, resulting in the birth of twins on November 16th, 2029. However, with no food left in the shelter, Diana and Sigma decide to copy the twin's atomic data into the Transporter in order to save them. Before starting the process, the couple gives their children their names. Diana names their son Delta, after Sigma who is also named after a Greek letter as well as having a "D"-name like her. Sigma names their daughter Phi in honor of Phi herself. Diana gives her daughter Phi's brooch and her son the bluebird music box. Needing a safe point to transfer their children, Phi and Delta's codes are sent prior to Zero II's acquisition of the devices, sometime before 2009. Diana and Sigma flip the switch, and hope that their children will live happier lives.
What happens to Sigma, Diana, the original Phi and Delta, and Gab is unknown. It is possible they were rescued, but it is also possible the five of them starved to death.
Force Quit: D
With all three teams spreading the votes during the first Decision Game as well as not pressing the yellow button in the Decontamination Room, D-Team, like the others teams, eventually awaken in the Lounge alive, but still by themselves. However, the mysterious Force Quit Box, which was previously closed, is now open for D-Team. Inside, the screen displays a message asking for "Mother's Mementoes".
If the D-2 Route is completed, Diana realizes that the mementoes refer to the gifts she gave to her children in that route. Suddenly, Diana receives a flash of memories through morphogenetic resonance. Recalling the events of the D-2 ending, Diana suddenly embraces Phi, realizing that Phi is in fact her daughter. Sigma and Phi also recall this history and Sigma embraces his family, having realized that their family has been reunited, but in another timeline.
CQD-END: 2 (Pay-off 2/The Final Decision)
In the True Ending route, Diana realizes both Phi and Delta are her children. Diana learns from Delta that she and Sigma were brought into the Decision Game to be stressed, causing epigenetic changes in their reproductive cells, in order to ensure the births of Phi and Delta.
Diana survives in the True ending of the game. Her fate after the events of the Decision Game in this ending is unknown, such as if she chooses to pursue the religious fanatic. It is unknown if she goes back to being a nurse, if she lives with Sigma and Phi, if she finally gets to avoid her ex-husband, if she and Rebecca make up, etc.
