Chiaki Nanami (七海 千秋 Nanami Chiaki), is a student of Hope's Peak Academy's Class 77-B, and a participant of the Killing School Trip featured in Danganronpa 2: Goodbye Despair. Her title is Ultimate Gamer (超高校級の「ゲーマー」chō kōkō kyū no “gēmā lit.” Super High School Level Gamer).
The AI takes the appearance of the real-life Chiaki, a teenage girl around the age of 17–18 years. 
Chiaki has short, pale mauve hair which is slightly curled. She wears a white clip in the shape of the spaceship from Galaga to the side of her face and has pale pink eyes. She wears a one button teal-grey cardigan with a symbol on the chest pocket and a hood that has pointed ears on the top and two pink eye-like markings on the front.
Chiaki is often seen wearing a pink cat-like backpack as well. Under her hoodie, she wears a white buttoned shirt with a pink ribbon and a pale beige skirt. Chiaki also wears black thigh high stockings and pink mary-jane style shoes.
She is seen wearing a ruffled white bikini and top during Chapter 2.
Chiaki normally has a quiet and sleepy disposition, but she becomes a lot more lively when discussing games and concentrates hard when playing. She has a number of unusual habits, such as dozing off while playing games and taking long pauses during her conversations to think about everything she wants to say. She sometimes even sleeps while standing and forgets to breathe when she's playing games. She also quite often uses gaming terms and references.
Chiaki is very calm and she once mentioned that she has never screamed. She often helps Hajime Hinata during the Class Trials and provides important points. She can be stern and bluntly honest, even at times forgetting to take other people's feelings into consideration.
While Chiaki is extremely observant and analytical, she lacks knowledge on a variety of ordinary subjects due to the nature of her existence. For example, she doesn't know where milk comes from (she mentions that she knows how babies are made, though). She doesn't really understand how romance or love works, is very curious about it. She also feels a bit uncomfortable around animals, because they're unpredictable and feel warm when touched, which is "a bit scary" in her opinion. She is occasionally a bit playful and tries to make jokes or play little pranks on Hajime, though they're a bit weird and sometimes borderline creepy.
Chiaki usually ends her sentences with a negative note even though she actually means to compliment someone or cheering someone, such as "...I think", or "Maybe...". Hajime once said that sometimes he wishes that Chiaki would end her positive sentence on a positive note. However, she truly does care about and wants to protect everyone. She dislikes killing more than anything and she gets very serious about the topic. She is the nicest towards Monomi and she is very understanding towards Nagito Komaeda, even though his actions frustrate her.
While she is based on some of human Chiaki's traits, AI Chiaki differs from her in some ways. Unlike the human, she appears constantly sleepy and her way of speaking is much less natural sounding. As an AI she also appears unusually calm and unfazed, even during her own execution, which is very different from the human Chiaki's much more human and painful reaction. She also has her own identity as an AI created by Chihiro, considering him her "dad" and Alter Ego and Usami her siblings. Some of Chiaki's behavior also appears a bit childlike, most notably her handwriting and drawings that resemble ones of a young child, which could be a result of her being a relatively young AI. However, she matures throughout the course of the game and in the end, she even seems to be able to resist her programming, albeit just a little bit.
Chiaki is the Ultimate Gamer, a talented person that is very good at any game, and even plays the "crappy" ones. She always finds out how to enjoy any genre or game that she plays. She states that the sole goal of playing video games is to have fun, and not to just focus on winning or losing. However, Chiaki does have one genre that she can’t play very well: Dating simulators. Also, Chiaki tends to focus too much when playing video games, to the point that she sometimes forgets to sleep and even breathe.

During the Tragedy
Being an AI, Chiaki has existed only for a few years and only exists inside the Neo World Program.
She was created either soon before or after the Tragedy started. Along with her "sister" Usami, she works for the Future Foundation and moderates the others on the virtual Jabberwock Island as NPCs/Observers.
She was created by Chihiro Fujisaki and considers him her father. Even though she has no memory of him, she has heard many things about him. She was presumably modified by her "big brother", Alter Ego, after Chihiro's death.
Inside the Neo World Program, Chiaki is seen playing Gala Omega when she meets Hajime. She introduced herself as the Ultimate Gamer and says that it was nice to meet Hajime, then she gave a polite bow. Hajime introduced himself, saying that it was nice to meet her as well. The two then shake hands.
Prologue - Welcome to Dangan Island!! Panic at the Heart-Throbbing School Trip!?
Chiaki stayed unusually calm in upheaval, such as when Usami revealed herself and when Monokuma took over the island from Usami and began the Killing School Trip. She did not believe anyone would kill, however.
When Hajime first sees her, she is deeply engrossed in a game at the Hotel Lobby, only stopping after Nagito calls her. She awkwardly introduces herself, Hajime stating that she isn't very good at conversations. Nagito then says that Chiaki is still playing the game, to which she agrees and she also states that she needs to compose what she's going to say in her head. Chiaki then states she's tired, ending the conversation.
Chapter 1 - Destination Despair
In the first chapter, Chiaki was worried about Monokuma infiltrating the party that the Ultimate Imposter arranged, so she stood guard outside the old hotel lodge alongside Monomi in order to keep Monokuma out of it.
Chiaki encountered Fuyuhiko Kuzuryu, who happened to walk by the lodge (though she suspected that Fuyuhiko actually did want to join the party). Because Chiaki was his alibi, knowing he did not enter the lodge, he was exonerated from murder suspicion. Chiaki also played an important role along with Gundham Tanaka, discovering a space under the lodge which the culprit had used as a spot to commit the murder.
Chapter 2 - Sea and Punishment, Sin and Coconuts
In the second chapter, Chiaki attended the girls-only beach party, for which she brought ice cream and some board games to play. Chiaki was excited when Monokuma gave them a new motive, namely Twilight Syndrome Murder Case. She explained to Hajime that she was a fan of the game series.
Chiaki as the Ultimate Gamer showed her ability to explain and help Hajime find the game's True Ending by pressing the “Down button five times”, and with this, they discovered a disclaimer that the game was actually based on a real-life event.
Chapter 3 - Trapped by the Ocean Scent
Chiaki made a crucial discovery which heavily altered the scene of the crime. The black curtains in the meeting room at the hospital were used by the culprit to make it seem like it was at the live house.
Chapter 4 - Do Ultimate Robots Dream of Electric Clocks?
In the fourth chapter, Chiaki and the other investigate the fourth island, riding the roller coaster and finally getting trapped by Monokuma in the Funhouse.
Chiaki stopped Hajime from entering the Final Dead Room. With the help of Nagito, Chiaki and Hajime were able to deduce the culprit.
Chapter 5 - Smile at Hope in the Name of Despair
Chiaki was revealed to have been the culprit in the fifth chapter. In an attempt to stop a fire, Chiaki accidentally killed Nagito, due to his efforts to reveal the traitor. Chiaki told Hajime that she was the traitor and he was forced to prove this to everyone.
They voted for Chiaki relying on Nagito's luck, and it was revealed that she was the true murderer, even though Komaeda was trying to keep the traitor alive as they were not influenced by despair. Chiaki and Monomi were executed afterwards.
Chapter 6 - This is the End Goodbye Academy of Despair
Despite her apparent death, Chiaki was able to appear in Hajime's thoughts during the final chapter's Graduation Session. Chiaki convinced Hajime to keep his head high, defeat AI Junko Enoshima and not to fall into despair.
Epilogue - The Day Before the Future
As the Neo World Program shuts down, Chiaki's voice could be heard, saying that she'll never forget anyone, as they will be friends forever.
Chiaki made a cameo apperance in Super Danganronpa 2.5 in Nagito's flashback with the rest of the surviviors.
AI Chiaki appeared to Hajime as a live depiction of his memory upon the boat leaving for Jabberwock Island. Clutching Usami in her arms, she recalled the time Hajime first entered the Neo World Program, when an A.I. was created to monitor them. She explained that it was everyone's desire to see her once more that brought her into the program, as a depiction of their memories. She acknowledged she is not the same Chiaki but still pointed out that the class were able to see her again.
Chiaki ended by expressing they all won a miracle together, Hajime, in response, stated that an ending like that wasn't so bad. Chiaki A.I. agreed, stating she fought and risked her life for this. Hajime and her both stared upon the rising sun, Chiaki stated they can all make their future together, she turned to Hajime and smiled once more. Nagito then called Hajime over so he wouldn't miss out on the food, Chiaki fades away as Hajime goes to join the others.
- Main article: Please Insert Coin
Both Chiaki and Usami are AI's and share a sibling relationship. The two are usually together, trying to protect the other students from Monokuma and from despair, as seen in Chapter 1 when the two were outside the old building during the Ultimate Imposter's party.
When Chiaki was found guilty and revealed as the mole for Future Foundation, the two were executed together.
Chiaki and Usami were created and sent into the Neo World Program by Future Foundation as a mole. Chihiro Fujisaki, who she referred to as her "father" was the one who created her while Alter Ego, who she referred to as her "big brother" was the one who modified her to be Chiaki.
In Danganronpa V3: Killing Harmony's non-canon Ultimate Talent Development Plan, Chiaki meets Chihiro and they act friendly towards each other, though they do not appear to be very close as she is a human and not the AI created by him.
- Killing School Trip Participants:
Chiaki quickly proved herself to be a useful help to Hajime in the investigations right from Chapter 1, having experience from murder mystery games. Though he thought she was a little odd and spacey, he respected her unusually sharp eye for detail. At the beach party in Chapter 2, he also became flustered at the sight of her in a bikini, implying he felt an attraction for her.
The two's bond is especially evident during Chapter 4 onwards and in Free Time Events. In the strawberry house in chapter 4, Chiaki is the only one who stops Hajime from entering the Final Dead Room, saying that he'd lose his way. During the Class Trials, Hajime frequently turned to Chiaki when the case seemed not to be going anywhere. Hajime generally sided with Chiaki during trials, and vice-versa.
When Chiaki confessed being the traitor in chapter 5, she relied on Hajime to prove her guilt. Much to the survivors' dismay, the group gave in to Hajime's reasoning and trusted Chiaki, believing that she was the murderer. Chiaki was also seen in Hajime's thoughts in chapter 6, willing him on to not give into despair.
Throughout various Free Time Events, it's hinted that the two were interested in each other romantically. In Chiaki's 4th Free Time Events, she fell into Hajime's chest while they were looking through storage boxes. Hajime commented about how fast his heart was racing and how they should meet together another time. In the 5th Free Time Events, the two of them “frolicked” around the island, with Hajime chasing her. It's later revealed that she wanted to have a “date” and was turning to Hajime for information.
At the end of the Free Time Events Hajime recollects that his partnership with Chiaki wasn't fake, and that if they escaped from the island, he would take Chiaki lots of places.
In Danganronpa V3: Killing Harmony's non-canon Ultimate Talent Development Plan, Chiaki is very close with Hajime as well and their relationship is based on the one they had in Danganronpa 3. Despite that fact, the event's "canonical" timeline showed a lot of inconsistency, to the point that whether she is the AI, the human Chiaki, or some blend of both, is difficult to discern.
At first, Chiaki and Nagito both do not pay much attention to each other. However, after the events of the first trial, when Nagito's true colors are revealed, Chiaki becomes the nicest person towards him, although she can be quite frustrated by him at times. Unlike other students, she is more understanding towards him and is not quick to accuse him of plotting something. Chiaki also appears concerned about Nagito's well-being when he's tied up, saying that she'll check on him later.
They provide each other with crucial information during class trials and Nagito even asks Chiaki to help him investigate at one point.
Although he is unaware of it, Nagito tries to save Chiaki (the traitor) by having her unintentionally murder him and get the other students killed. However, this fails when Chiaki revealed herself as the traitor among the students. When Chiaki was about to be executed, she had no ill will towards Nagito, believing that the difficult circumstances were the reason for his extreme behavior.
Chiaki and Mikan are shown to be on very friendly terms with each other.
In Chapter 2, Chiaki is shown to be spending time with Mikan in the Mirai Hotel lobby. Mikan remarks how kind Chiaki was for teaching her how to play games, and even playing a round against her. Right after Mikan explains that she was happy to be able to play with a friend, which is one of the few instances where Mikan does not apologize for assuming that someone is her friend. After being thanked, Chiaki interjects by saying that Mikan doesn't need to thank her as she had fun too. Hajime's internal dialogue highlights this as he notes how this was the first time he had ever seen Mikan that happy, and that he should thank Chiaki for it.
In Chapter 3, Chiaki is shown to be clearly disappointed in Mikan after the latter gets infected by the Despair Disease and recalls her memories as Ultimate Despair. Because of their previous interaction and Chiaki's nature as an AI, this can be due to not being able to rehabilitate Mikan as she was supposed to, and feeling disappointed in herself. Though it can also be taken as Chiaki simply being upset about losing a friend she had made herself.
In the same chapter, during the trial, the localization has Chiaki remark the retelling of Mikan sleeping on Hajime as "too much info". In the original Japanese, she says "gochisōsama" in response, which can be taken as sarcasm, as it's a phrase used most often after eating/being treated to a meal, which roughly means "thank you for the meal".
Sonia is a close friend of Chiaki's. They are often seen talking together and get along very well. In the fifth class trial after Chiaki revealed herself as the traitor from the Future Foundation, Sonia kept denying it, saying that she couldn't have been the traitor. Sonia considered Chiaki as one of her beloved comrades that experienced so many things in the Killing School Trip. Sonia went too far in proving that Chiaki is not the traitor by engaging in a rebuttal showdown with Hajime.
Free Time Events & Bonus Mode Guides
The links below are full transcripts and indepth guides for Chiaki Nanami's relationship routes in Free Time Events, School Mode, and Ultimate Talent Development Plan including her MonoMono Machine Present preferences and most effective dialogue options.
|Free Time Events||Island Mode||Ultimate Talent|
- Nanami (七海) means “Seven Seas” while Chiaki (千秋) means “One Thousand Autumns”.
- Chiaki shares her birthday, March 14, with that of her creator's, Chihiro.
- Another similarity between Chiaki and Chihiro is that both of them have kanji numerals in both their given names and last names, with the numerals in their first names both being 千 chi, which means "thousand".
- Chiaki's relation to Chihiro is also subtly hinted at through their similar promotional illustration art. The only differences between the two is that Chihiro, being a programmer, is surrounded by computers while Chiaki is surrounded by game consoles, and that Chihiro is seated in a chair while Chiaki seems to be sitting on a floor.
- In Chiaki's character illustration features a Game Boy Advance SP, a PlayStation 2 slim, a GameCube, a Nintendo DS, a Game Boy, a Game Gear, a PS3, a Sega Saturn, an Xbox, an Xbox 360, and a Famicom.
- Chiaki enjoys any kind of video game, even games falling under the "kusoge" genre (games intentionally designed to be unlikable), with the exception of dating sims, the only genre she is bad at.
- In her Free Time Events, Chiaki will talk about or reference other video games, like "Trio The Punch", and "Dead Rising".
- In Chiaki's cottage, the same "Time Travelers" (a game by game company Level-5 written by Chunsoft's writer Jirou Ishii) poster as the one seen in the cinema can be spotted. In the Vita and PC versions, this is changed to a poster for "Danganronpa Another Episode: Ultra Despair Girls" in both the cinema and her cottage.
- Chiaki doesn't like the idea of swimming, because she fears she might fall asleep and drown.
- Chiaki doesn't know about Girls' Day (Hinamatsuri), a holiday in Japan where families pray for the health of their daughters, until Hajime told her. This is a hint to the fact that Chiaki is an AI.
- Chiaki was featured in the last formal executions, while the real-world Chiaki she was based upon was featured in the first formal execution.
- AI Chiaki's execution mirrors Junko's, with both of them going through several sequences before ultimately getting crushed to death.
- Interestingly, real-world Chiaki's death in Despair Arc is very similar to Mukuro's death in Danganronpa: Trigger Happy Havoc: being suddenly impaled by dozens of spears. The deaths also double as acts of betrayal from those who were closest to them (Junko, in Mukuro's case, and Chisa, in Chiaki's case).
- Considering these facts, it's also worth noting that Mukuro was the first person to be executed during the Killing School Life, while Junko was the last.
- In the stage play, AI Chiaki is executed by spear impalement, just like her real-world counterpart.
- Chiaki is the only one of the eight characters shown on the cover of Danganronpa 1 ・2 Beautiful Days who is not shown in her promotional art.
- According to the series creator, Kazutaka Kodaka, the Chiaki who appeared to help Hajime during Chapter 6 of Danganronpa 2 didn't feel like the same Chiaki who appeared during most of the game, giving him the idea of another, different Chiaki—her real life counterpart.
