Chiaki Nanami (Danganronpa 2)

Chiaki Nanami (七海 千秋 Nanami Chiaki) is one of the characters featured in Danganronpa 2: Goodbye Despair. She has the title Ultimate Gamer (超高校級の「ゲーマー」Chō Kōkō Kyū no "Gēmā"). She is actually revealed to be an AI created by Alter Ego to be a mole for the Future Foundation. She is the culprit of Chapter 5, where she is tricked into accidentally killing Komaeda.

Appearance
Nanami has short, light pink 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 an unzipped dark green hoodie which has pointed ears on the top of her hood and two pink markings on the front. She is often seen wearing a pink backpack as well. Under her hoodie, she wears a white buttoned shirt with a pink ribbon and a pale brown skirt. Nanami also wears black thigh highs and white shoes.

Personality
Nanami normally has a sleepy disposition, but she concentrates hard when she plays games. She often helps Hajime Hinata during school trials and provides important points. Nanami can also be stern when she tells people to do things and becomes a lot more lively when discussing games.

Nanami has a number of unusual habits, such as dozing off while playing games and taking long pauses during her conversations to think everything she wants to say. She is extremely observant and analytical, but lacks knowledge on a variety of ordinary subjects.

She 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". Hinata once said that sometimes he wishes that Nanami would end her positive sentence with a positive note.

History
[Warning: Several spoilers follow this section!]

Pre-Despair Incident
Nanami is not an actual human, and as a result, did not have a life before the Malefaction. Instead, after the Malefaction started, she was created as an AI along with Usami to moderate the others on the island. She was created by Alter Ego.

Island Life of Mutual Killing
In the beginning, Nanami is able to stay calm in all situations, such as when Usami reveals herself and when Monokuma reveals that they have to kill to get off the island. She does not believe anyone will kill, however.

Worried about Monokuma inflitrating the party, Nanami stands guard outside of the old hotel lodge to keep Monokuma out of it, along with Usami. While standing guard, she encounters Kuzuryuu, who was happening to walk by the lodge. (Though she suspects this is because Kuzuryuu actually did want to join the party.) This becomes valuable evidence for proving Kuzuryuu innocent, as it shows that he did not enter the lodge, and as a result, could not have killed Togami . Nanami also play an important role along with Tanaka. Both of them discovered a space under the lodge, that culprit used as the murder place.

In the second chapter, Nanami attends the girls-only beach party, by brought ice creams and some games to be played. Nanami were excited when Monokuma gave them a new motive, namely "Twilight Syndrom Murder Game". She explain to Hinata that she is the fans of the game series. Nanami as Ultimate Gamer showed her ability to Hinata, explain and helped him to found the true ending of the game by entered "Down-Up-Left-Left" button, with this, they could stated that the game are based on real life story.

In the third chapter, To avoid despair fever spreading, Nanami along with Sonia, Tanaka, Souda , and Saionji move to the motel in the thirds island. Nanami makes a crucial discovery that heavily alters the scene of the crime. The black curtains in the meeting room at the hospital, to make it seem like it was at the live house, was used by Mikan Tsumiki. Tsumiki tricked Mioda into filming herself climbing up a ladder and hanging herself, though this was staged and convinces Hinata to check the live house, where he discovers Ibuki Mioda and Hiyoko Saionji dead.

Nanami is revealed to have been the culprit in Chapter 5. In an attempt to stop a fire, Nanami accidentally kills Komaeda, through his efforts to reveal the traitor. Nanami tells Hinata that she is the traitor, and Hinata is forced to prove this to everyone. They vote for Nanami, relying on Komaeda's luck, and it is revealed that she is the true murderer, even though Komaeda was trying to keep the traitor alive as they were not influenced through despair. Nanami is executed afterwards.

Nanami appears in Hinata's thoughts at Chapter 6. Nanami convinces Hinata to keep his head high, and defeat Enoshima Junko and not fall in despair. As the New World Program shuts down, Nanami's voice can be heard, saying that she'll never forget anyone, as they will be friends forever.

Execution

Usami
Both Nanami and Usami were created by Alter Ego. The two are usually together, trying to protect the other students from Monokuma and them falling into despair, as seen in Chapter 1 when the two are outside the beach house during Togami's party. When Nanami is found guilty, the two are executed together.

Hinata
The two's bond is especially evident during chapter 4 onwards and in free-time events. In the strawberry house in chapter 4, Nanami is the only one who stops Hinata from entering the Final Dead Room, saying that he'd lost his way. As no one else had even known his whereabouts at the time, it is implied that she genuinely cared for him. During class trials, Hinata frequently turned to Nanami when the case seems to be going nowhere. Hinata generally sides with Nanami during a case, and vice-versa.

When Nanami confesses as being the traitor in chapter 5, she relied on Hinata to prove her guilt. Much to the survivors Hinata's and dismay, the group gave in to Hinata's reasoning and trusted in Nanami, believing that she was the murderer. Nanami is also seen in Hinata's thoughts in chapter 6, willing him on, and to not fall into despair.

Throughout various free-time events, it's hinted that the two were interested in each other romantically. In Nanami's 4th free-time event, she falls into Hinata's chest while they are looking through storage boxes. Hinata comments about how fast his heart was racing and how they should meet together another time. In the 5th free-time event, the two of them "frolick" around the island, with Hinata chasing her. It's later revealed that she wanted to have a "date" and was turning to Hinata for information.

At the end of the free-time event Hinata recollects that his partnership with Nanami wasn't fake, and that if they escaped from the island, he would take Nanami lots of places.
