Personality
Koizumi is an optimistic and sensible girl who is generally rather calm. She might come off as a little rude; but in fact, she's a girl that's not afraid to state her mind. She's very confident and wants men to act properly. She is harsher towards men, but she doesn't dislike them. Koizumi wants to help as many people as she can, however, if you're being impolite, then she won't hesitate to either scold you or let you suffer consequences. Koizumi hates people who lack manners, but it is never said that she hates men. She at first thought of her title of photographer as stupid compared to everyone else's.

History
Pre-Despair Incident

During her stay at Hope's Peak Academy, Koizumi was revealed to have an especially close friendship with Ibuki Mioda, Mikan Tsumiki, and Hiyoko Saionji. Free time interactions with her reveal that she wanted to follow in her mother's footsteps as a photographer, thus gaining her title as "Super High-school Level Photographer". Koizumi reveals that she feels inferior to the other students when comparing her talent to theirs, but Hinata reassures her by pointing out her good points.

Island Life of Mutual Killing
After receiving a note from Kuzuryuu, Koizumi decides to play the game Twilight Syndrome. There, she regains her memories and feels compelled to ask everyone involved in the game to talk to her about it. She invites Kuzuryuu, Saionji, Mioda, Pekoyama 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 Kuzuryuu's behalf using a metal bat, incidentally recreating the final scene in the Twilight Syndrome game. Saionji witnessed said murder, and escaped the beach house. 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.
