Mahiru Koizumi (小泉 真昼 Koizumi Mahiru) is one of the characters featured in Danganronpa 2: Goodbye Despair. Her title is Ultimate Photographer (超高校級の「写真家」chō kōkō kyū no “shashinka”).
Mahiru's appearance consists of an olive-green school jumper with a cream-and-orange tie, which she knots around the collar of her white uniform shirt. She is nearly always seen with a camera, which she carries on an orange shoulder strap. She wears knee-high socks in a slightly darker shade of olive green the her outfit, and her shoes are a dark shade of forest green. Directly below the opening of the socks, there is a small orange symbol. She wears her hair in a short, slightly choppy crimson bob, and her eyes are almost the same color of her jumper. It should be noted she has a light dusting of freckles on her nose.
Mahiru 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. Mahiru compares her photographs to those of her mother, a famous war photographer whose career led her to be absent from home for much of Mahiru'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.
Mahiru 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. Mahiru is introduced as hating people who lack manners, though she later develops a very close friendship with Hiyoko.
She thinks her title of “Ultimate Photographer” is stupid compared to everyone else's.

Prior to the Tragedy
During her stay at Hope's Peak Academy, Mahiru 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 Fuyuhiko'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”. She also had an unemployed father who didn't help Mahiru do the house chores when her mother was gone. Mahiru says that she feels inferior to the other students when comparing her talent to theirs.
Island Life of Mutual Killing
Prologue - Welcome to Dangan Island! Panic at the Heart-Throbbing School Trip!?
Hajime first finds Mahiru near the Lodge in Hotel Mirai. Mahiru directly scolds Hajime, because he had lost consciousness and Mahiru said that he must protect the girls. Nagito introduced her to Hajime, stating that he heard Mahiru had won all kinds of photography awards, saying that she is best known for her characteristic portrait. At first, Mahiru doesn't seem flustered like the other students when they first arrived at the island. In fact she actually replies saying that she thinks Hajime and Nagito are decent stating that most of the others are wierdos. Mahiru is also the one who explains that after you collect all the Hope Fragments, they all get to leave off the island together. When Hajime starts freaking out over it she starts scolding him again for not paying attention. Mahiru than asks Hajime about his introduction, and after his introduction Mahiru labels him "Unreliable Hijime". She tells both him and Nagito to man up and to do better.
Later when Usami tells everyone to head to the beach and Byakuya asks everyone for their opinions on the island. Mahiru is the 6th person to talk, saying that the hotel is nice and that she wishes they were staying there. After the discussion of Jabberwock Island she says that she is a tad less worried now. She also calls Akane's solution stupid. She and a few other students receive Usami's presents happily and when Usami says that they can have a party Mahiru cheerfully suggests a campfire. Mahiru is one of the many students excited to go swimming.
Chapter 1 - Destination Despair
The next morning, Mahiru attended Byakuya's meeting at the hotel restaurant. All students had arrived, except Kazuichi Soda, Mahiru then dragged Kazuichi with her to the hotel restaurant, in order to start the meeting. Having done so with Kazuichi, Mikan suddenly fell in a weird pose, Mahiru quickly helped her up, aside from Hiyoko's insults and Ibuki and Teruteru's lewdness. When the problems were solved, Byakuya started the meeting with a declaration that he'd lead the groups until they escaped from the island, which made Mahiru 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 “decoration”, Sonia told her that a leader would have protect his men, something Byakuya appeared willing to do, and after that, Mahiru accepted Byakuya as the leader.
During the party, Mahiru is willing to take her friends picture. When the murder occurred, this photograph help the students to deduce the person who set up the blackout plan.
Chapter 2 - Sea and Punishment, Sin and Coconuts
In the beginning of Chapter 2, her friendship with Hiyoko bloom after she was willing to help Hiyoko solve her problem by taking a bath with her and teaching her how to tie her kimono obi. And after she heard that Nagito was tied in the Old Lodge, she forced Hajime to bring him breakfast. But actually, she had met with Nagito, who later told her to play the second motive, Twilight Syndrome Murder Case but she decided to not played it until she received a file filled with real life photos from Fuyuhiko, Mahiru finally decided to play the game. There, she regains her memories and feels compelled to ask everyone involved in the game to talk to her about it. She invites Fuyuhiko, Hiyoko, Ibuki and Mikan to the beach house, but the latter four declined due to having a previous engagement - Sonia's girls-only swimming trip. When Peko heard Mahiru and Hiyoko's plan to discuss about Twilight Syndrome Murder Case, she quickly sent them a fake message. Peko sent a message to Hiyoko (Peko sent the message using Mahiru's name) to meet Mahiru in Beach House at 2.00 a.m. and Peko sent a message to Mahiru (Peko sent the message using Hiyoko's name) at 2.30 a.m.
Mahiru came to the beach house right at 2.00 a.m., where she was met with Fuyuhiko and caught in an argument about the current motive. Just a second before Fuyuhiko went into action, Mahiru was then bludgeoned on the head by Peko on Fuyuhiko's behalf using a metal bat, incidentally recreating the final scene in the Twilight Syndrome Murder Case.
In Chapter 3, Hiyoko made a shrine dedicated to Mahiru to recall her kindness.
Even though Mahiru is the same age as Hiyoko, she treats her as a younger sister, such as helping her with her clothing and taking baths with her. She was the only one that Hiyoko refereed with respect.
Mahiru often scolded the Ultimate Yakuza 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 on during Chapter 2, Fuyuhiko was invited by Mahiru to go to the Beach House on the Second Island to discuss the current motive. But they got into another argument, this time the argument was stopped by Peko who killed Mahiru in the same fashion as Sato.
Before Mahiru got dragged to the Jabberwock Island with the others, she developed a friendship with Sato, one of Hope's Peak talented student. Mahiru and Sato were friends with Mikan, Hiyoko and Ibuki. One day, Sato was tired of seeing Mahiru being bullied by Fuyuhiko's sister, when she attempt to stop her bullying action in peace, Sato ended up murdering Fuyuhiko's sister in the music room. Mahiru knew this and promised she would cover her by destroying the evidence. When Sato's body was found she was the only one out of the group of friends to cry.
Mahiru and Fuyuhiko's sister shared the same photography class, but for some unknown reason (Most likely due to Mahiru's photos being better than Fuyuhiko's sisters') Fuyuhiko's sister started bullying Mahiru.
