Chiaki Nanami

Chiaki Nanami is a character from the Danganronpa 2: Goodbye Despair game.

Chiaki is a student of Hope's Peak Academy's Class 77-B, and a participant of the Killing School Trip.

Her title is Ultimate Gamer.

Appearance
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 outwards with short straight bangs. Additionally, her strands also curl inwards. 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 dark 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. She also has stripe decorations at the bottom of her cardigan that appear to pale gray.

Chiaki is often seen wearing a paler pink cat-like backpack as well that has a white ribbon and a white pocket at the bottom. Under her hoodie, she wears a white buttoned shirt with a black shirt line, with a pink ribbon and a pale beige skirt. Chiaki also wears black thigh high stockings and light pink mary-jane style shoes with white soles.

She is seen wearing a ruffled white bikini with a ribbon and ruffled pants during Chapter 2.

Personality
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 Hinataduring 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.

Ultimate Gamer
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.

Trivia

 * Nanami means “Seven Seas” while Chiaki 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 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.
