I am who I am now because of everything that's happened. If I try to deny my past, I'm denying the person I've become.

Iori Nagase (永瀬 伊織, Nagase Iori) is one of the main characters of Kokoro Connect series. She is the president of the Student Cultural Society. She attends the same homeroom as Taichi and Inaba and is seen as a bright and popular individual amongst her peers. A bold and dynamic character, Iori endeavors to bring excitement and fun to the Cultural Club and later develops into the voice of reason amongst her friends, keeping peace during times of strife. Iori also lives alone with her single mother who is often out.

Character Overview


Iori is generally shown to be energetic, playful, and strongly opposed to negative feelings, working tirelessly to relieve tensions and keep things light-hearted. Also, due to previously having a violent stepfather, she has developed a habit of altering her personality to fit the expectations of others. As a result, Iori presents herself as especially courteous when around authority figures and especially cheerful when she's around her friends. Iori enjoys making perverted jokes and tongue twisters which Taichi often finds himself roped into.

After Michi Random, Iori expresses herself much more freely, embracing the good and bad parts of herself, even being violent when necessary. She is also the one that keeps everyone together, giving wise advise to the rest of the club and looking after the 1st years.

In Yume Random, Iori, because she likes working with kids, decides that she will be a teacher in the future. In Precious Time, Iori decides to go to a university and major in education. She received a recommendation from Yamaboshi High, and also began doing volunteer work as a teacher for an affiliated elementary school in her free time.

Key Problem

Growing up with five fathers, Iori adapted to her changing conditions by acting with different personalities to appease everyone's expectations of her. As Iori constantly changed her behavior for the people around her, she realized that she has, overtime, lost touch of her original personality. Throughout the series, Iori strives to find her true self so she can stop pretending to be someone she feels she's not.


Iori is considered to be very cute and big busted body. She wears her shoulder-length, dark-purple hair in a pigtail with a pink scrunchy on the left side. She has dark-blue eyes and a beauty mark on her face, just below her mouth. Iori is usually seen wearing her school's uniform and opts to wear shorts underneath her skirt. In later volumes of the novel, Iori is shown to abandon her pigtail, allowing her hair to flow freely.

Background History

When required to choose a club to join, Iori could not favor any club over the others and decided to make her homeroom teacher, Gotou, randomly choose for her. As a result, Iori was placed in the Student Cultural Society. Iori was initially against becoming the club's president, but reluctantly accepted the role after losing a game of rock-paper-scissors.

Iori grew up with five different father figures in her life. Her 2nd father was very violent, so Iori would change her personality to appease him and keep him from harming her and her mother. Ever since then, Iori has made it a habit to alter her behavior to meet the expectations of everyone around her. Iori's 5th father, who passed away during Iori's 3rd year in junior high, encouraged her to "live her own life",[1] a task she was unsure how to fulfill at this point.
