History
[Warning: Several spoilers follow this section!]

Prior to the Tragedy
Chiaki is not an actual human, and as a result, did not have a life before the Tragedy. 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. This fact is revealed in the last trial, after Monokuma mentioned both Chiaki and Usami was a NPC/Observer of the Future Foundation.

Island Life of Mutual Killing
In the beginning, Chiaki is able to stayed calm in all situations, such as when Usami revealed herself and when Monokuma took over the island and forced them to killed if they wanted to get off the island. She does not believe anyone will kill, however.

In Togami's party in the first chapter, she worried about Monokuma inflitrating the party, Chiaki stands guard outside of the old hotel lodge to keep Monokuma out of it, along with Usami. While standing guard, she encounters Kuzuryu, who was happened to walk by the lodge. (Though she suspects this is because Kuzuryu actually did want to join the party.) This becomes valuable evidence for proving Kuzuryu innocent, as it shows that he did not enter the lodge, and as a result, could not have killed Togami . Chiaki 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, Chiaki attends the girls-only beach party, by brought ice creams and some games to be played. Chiaki were excited when Monokuma gave them a new motive, namely Twilight Syndrome Murder Mystery. She explained to Hajime that she is the fans of the game series. Chiaki as Ultimate Gamer showed her ability to explained 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, Chiaki along with Sonia, Tanaka, Soda , and Saionji move to the motel in the thirds island. Chiaki 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 Hajime to check the live house, where he discovers Ibuki Mioda and Hiyoko Saionji dead.

In the forth chapter, she was the person who stoped Hajime, before entering the Final Dead Room. But later, Komaeda entered the Final Dead Room due to his eagerness to helped the students revealed the culprit of the fourth chapter. By the helped of Komaeda, Chiaki and Hajime were able to deduce the culprit.

Chiaki is revealed to have been the culprit in Chapter 5. In an attempt to stop a fire, Chiaki accidentally kills Komaeda, through his efforts to reveal the traitor. Chiaki tells Hajime that she is the traitor, and Hajime is forced to prove this to everyone. They vote for Chiaki, 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. Chiaki is executed afterwards.

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

Execution

Usami/Monomi
Both Chiaki 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 Chiaki is found guilty, the two are executed together.

Hajime Hinata
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 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, Hajime frequently turned to Chiaki when the case seems to be going nowhere. Hajime generally sides with Chiaki during a case, and vice-versa.

When Chiaki confesses as being the traitor in chapter 5, she relied on Hajime to prove her guilt. Much to the survivors Hajime's and dismay, the group gave in to Hajime's reasoning and trusted in Chiaki, believing that she was the murderer. Chiaki is also seen in Hajime'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 Chiaki's 4th free-time event, she falls into Hajime's chest while they are looking through storage boxes. Hajime 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 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 event 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.
