Personality
Koizumi is an optimistic and sensible girl who is generally rather calm and unafraid to speak her mind. She initially comes off as confident, but is later revealed to have self-esteem issues. Koizumi compares her photographs to those of her mother, a famous war photographer whose career led her to be absent from home for much of Koizumi's life. Her father was a very poor parent, leaving the responsibility of the housework entirely to her.

She has high expectations of men and is quick to be abrasive towards them. She is much more tolerant and friendly to girls. The subjects of her photos are usually of girls, and she tells Hajime that she easily gets bored of photographing guys.

Koizumi wants to help as many people as she can, but is not a pushover- she doesn't hesitate to scold those who are rude to her. Koizumi is introduced as hating people who lack manners, though she later develops a very close friendship with Saionji.

She thinks her title of "Ultimate Photographer" is stupid compared to everyone else's.

History
[Warning: Several spoilers follow this section!]

Prior to the Tragedy
During her stay at Hope's Peak Academy, Koizumi is revealed to have an especially close friendship with Ibuki Mioda, Mikan Tsumiki, and Hiyoko Saionji. During her stay, she joined the photography club with Kuzuryu's sister. She was then bullied by the latter.

Her Free Time Events reveal that she wanted to follow in her mother's footsteps as a photographer and gain her title of "Ultimate Photographer." Koizumi says that she feels inferior to the other students when comparing her talent to theirs.

Island Life of Mutual Killing
Hajime first finds Koizumi near the Lodge in the Hotel. Koizumi directly scold Hajime, because he had lost consciousness and Koizumi said that he must protect the girls. Komaeda introduced her to Hajime, stating that he heard Koizumi had won all kinds of photography awards. Koizumi's best known for her charateristic portrait. At first, Koizumi doesn't seem flustered like the other students when they first arrived at the island. She and few other students receive Usami's presents happily. They enjoyed the presents at the first beach until Monokuma ruined everything.

In the next morning, Koizumi attended Togami's meeting at the hotel restaurant. All students had already arrived, except Kazuichi Soda, Koizumi then dragged Soda with her to the hotel restaurant, in order to start the meeting. Having done with Soda, suddenly Tsumiki fell in a weird pose, Koizumi quickly helped her up, aside Saionji"s insults and Mioda and Hanamura lewdness. Just when the problems were done, Togami started the meeting with a declaration that he'd lead the groups until they escaped from the island, which made Koizumi rather annoyed by his aggressive declaration, she preferred Sonia Nevermind, mainly because she thought that Sonia's made her fit to be a leader. But Sonia told her that her title is just for a "decoration", Sonia told her that a leader would have protect his men, something Togami appeared willing to do, and after that, Koizumi accepted Togami as the leader.

When Togami throw a party, Koizumi is willing to take her friends picture. When the murder occured, this photograph deduce the person who set up the black out plan.

In chapter 2 After receiving a note from Kuzuryu, Koizumi decides to play the game Twilight Syndrome Murder Mystery. There, she regains her memories and feels compelled to ask everyone involved in the game to talk to her about it. She invites Kuzuryu, Saionji, Mioda and Tsumiki to the beach house, but the latter four decline due to having a previous engagement - Sonia 's girls-only swimming trip. Koizumi was then bludgeoned on the head by Pekoyama on Kuzuryu's behalf using a metal bat, incidentally recreating the final scene in the Twilight Syndrome Murder Mystery.

Saionji witnessed said murder, and escaped the beach house via the front door. Her death is avenged thanks to the efforts of Hajime Hinata, Nagito Komaeda, and Chiaki Nanami.

Hiyoko Saionji
Even though Koizumi is the same age as Saionji, she treats her as a younger sister, such as helping her with her clothing and taking baths with her.

Fuyuhiko Kuzuryu
Koizumi often scolded the Ultimate Gangster when he would mouth off to his classmates, resulting in arguments between the two that had to be broken up by the others, usually Komaeda or Hajime. Later at Chapter 2, Kuzuryu invite Koizumi at Beach House at Second Island to discuss the curent motive. But they caught up at arguments and Koizumi killed by Pekoyama in result.

Satou
Before Koizumi got dragged to the Dangan Island with the others, she develop a friendship with Satou, one of Hope's Peak talented student. Koizumi and Satou also team up with Tsumiki, Saionji and Mioda. At one day, Satou was tired looking at Koizumi who being bullied by Kuzuryu's sister, and attempt to murder her.
