Iori Nagase

Nagase Iori (永瀬 伊織) is the President of the Student Cultural Society Club. She attends the same homeroom class as Taichi and Inaba and is seen as a bright and popular person amongst her peers. A bold and dynamic character, Iori acts as the mood maker for the group, bringing excitement to their daily lives. Iori also lives alone with her single mother who is often out.

Personality
Iori is often 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 is shown to be especially courteous around authority figures and especially cheerful when she's around her friends.

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 feels that she has, overtime, lost touch of her original personality. Throughout the series, Iori strives to find her original self so she can stop pretending to be someone she feels she's not.

Appearance
Iori is considered to be very cute and wears her shoulder-length, dark-purple hair in a pigtail 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 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 or 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", a task she was unsure how to fulfill.
