Description
Izumi Katsuragi is a main character in the Love Live! Hasu no Sora Jogakuin School Idol Club project. She is a second-year student at Hasunosora Girls' High School, enrolled with the 105th class, and is a member of the school's idol club. Her image color is chevalier green.

Izumi was initially introduced as a supporting character and a rival. In her debut appearance, she was a first-year student at Mizukawa Girls' School before transferring to Hasunosora following the closure of her previous school. Before her involvement in school idols, she attended school in Tokyo and accumulated a diverse range of accomplishments, including winning an award for acting, first place in a national fencing competition, and first place in a programming competition. She first encountered her partner, Ceras Yanagida Lilienfeld, on a rainy day outside Izumi's school grounds in Tokyo. Ceras confided that her school was closing and that she needed to win Love Live! to save it. Izumi almost instantly agreed to help, offering to transfer schools just to win for her. In return for this pledge, Ceras agreed to give her everything. To hone her skills for this goal, Izumi entered numerous competitions, accumulating about twenty performances in only nine months. She won every single one, though she claims they were all narrow victories.

In terms of personality, Izumi is a highly skilled dancer whose maturity and looks belie her young age. She has a habit of referring to herself as onee-san, or big sister, even among girls her own age. She is very perceptive when it comes to performances and can instantly identify where someone is lacking. She is a tenacious and self-confident individual who takes her duty to win very seriously, going so far as to say that her entire reason for living is to make Ceras's dream come true. She explains this dedication by stating that she loves people who chase their dreams. Despite her immense talent and ability to handle most things with ease, she does not actually take any personal pleasure in winning itself.

Izumi's role in the story is closely tied to her partnership with Ceras. Together, they form the previously independent school idol duo Edel Note, which later falls under the Hasunosora Girls' High School Idol Club. Her initial interaction with the main group occurs when she meets the 104th class at a park and gives them advice on why they are not synchronizing correctly in their performances. Her core motivation is singular and unwavering: to make Ceras's dream a reality. This commitment is so total that Ceras herself compares Izumi to a demon who made a deal with the devil for power.

Regarding development, Izumi's journey is defined by her transition from a rival soloist attending a different school to a transfer student and key member of the Hasunosora Idol Club. She is noted as the second school idol overall to debut as a soloist, and the first to do so while also being part of a unit. Her partnership with Ceras is the most significant relationship in her life, with Izumi having pledged her entire existence to supporting Ceras's ambitions. Izumi's notable abilities extend beyond performance; she is extremely talented in a wide array of fields, including sports such as sprinting, and has proven skills in acting, fencing, and programming. Her specialty, as she describes it, is replicating examples. Her hobbies include physical activity and people watching.
