Mahiru Koizumi is a student of Hope's Peak Academy's Class 77-B, and a participant of the Killing School Trip featured in Danganronpa 2: Goodbye Despair. Her title is the Ultimate Photographer. 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. When Hajime Hinata was being scolded by Mahiru, he likened it to being yelled at by his mom. Mahiru has high expectations of men and is quick to be abrasive towards them. She is much more tolerant and friendly to girls. In the original Japanese, she refers the girls in her class with their first name and "-chan" honorifics, while she refers the guys casually with their last name only. The subjects of her photos are usually of girls and explains that she easily gets bored of photographing guys. She loves taking photos of people's smiles, and it's revealed in her Free Time Events that she recorded everything in Jabberwock Island so that they won't forget, except for the guys which she only recorded once every three days. Despite her love for photography, Mahiru believes her title is stupid compared to her classmates. She has been shown to dislike selfies.

Danganronpa
A group of 15 elite high school students are gathered at a very special, high class high school. To graduate from this high school essentially means you'll succeed in life, but graduating is very difficult. The school is presided over by a bear called Monokuma, and he explains to them that their graduation hinges around committing a murder. The only way to graduate is to kill one of your classmates and get away with it. If the other classmates discover the identity of the killer, the killer is the only one executed. However, if they fail to catch the killer, only the killer graduates and the others are annihilated. Which of the 15 will survive the bloodbath to come?

Danganronpa 3: The End of Hope's Peak High School - Despair Arc
Hope's Peak Academy's unconventional class 77-B is about to have an even more eccentric addition: Chisa Yukizome, an alumna with the title of Super High School-Level Housekeeper—and their new homeroom teacher. Cheerful, passionate, and capable, Chisa immediately sets about correcting the students' problematic behavior and strengthening their relationships. It may not be easy dealing with diverse pupils ranging from princesses and nurses to yakuza and impossibly lucky students, but anything is possible with the power of hope. Meanwhile, Hajime Hinata, an unremarkable boy from the school's Reserve Course, longs for a talent. One day, he has an unexpected meeting with class 77-B's Super High School-Level Gamer Chiaki Nanami, who presents to him a new, hope-filled outlook on life. However, unbeknownst to him, the school's upper echelon is about to execute a sinister project centered around Hajime that will bring Hope's Peak—and the rest of the world—to its knees. Zetsubou-hen chronicles the daily lives carried out at the talent-cultivating academy, and the darkness that lurks beneath. As despair slowly infects hope, plans are put into motion to start the Biggest, Most Awful, Most Tragic Event in Human History, and the end begins.
