Nanami Hisami is a character from Wake Up, Girls! New Chapter and a member of the idol group Wake Up, Girls!. She is the youngest member of the group, being a second-year middle school student at the start of the series. Nanami has been training in singing, dancing, and playing the piano since she was very young, and she holds a deep admiration for the Hikarizuka Revue, a theatrical performance group. Her background in disciplined training gives her a strong technical foundation as a performer compared to some of the other members.

In terms of personality, Nanami is described as prideful and social. She carries herself with a confident and sometimes haughty demeanor, and she holds herself to high standards. She is ambitious and eager to succeed as an idol, which drives her to constantly practice and improve. While she initially comes across as full of herself, her pride is rooted in a genuine desire to conduct herself well and meet the expectations she sets for herself. She tries to project a powerful and confident image even when she feels nervous or uncertain, often brushing off her own insecurities rather than showing vulnerability.

Nanami's primary motivation is to become a successful idol. Her dedication to her craft is evident in her continuous training and her insistence on not settling for mediocrity. She possesses a strong competitive streak and dislikes the idea of losing or retreating in defeat. This drive is reflected in a key moment when the group faces a setback and debates returning to Sendai from Tokyo; Nanami firmly rejects the idea of going back without achieving success, declaring that she absolutely hates returning in defeat.

Her role in the story is that of the youngest and most technically trained member of Wake Up, Girls!. Her pride and competence sometimes create a contrast with other members who are less experienced or more uncertain, but she also acts as someone who pushes others to reach their potential. She occasionally complains about tasks but is more likely to be the one encouraging or gently chastising fellow members for not working hard enough.

In terms of development, a significant turning point occurs when Nanami is faced with a decision between continuing with Wake Up, Girls! and pursuing an entrance exam for another opportunity. While waiting alone at an airport, she reflects on her memories and experiences with the group, realizing how important the other members and the group itself are to her. This realization leads her to choose to remain in Wake Up, Girls! and participate in the finals, prioritizing her bonds with the group over her individual aspirations. This moment highlights her growth from a prideful individual focused on personal achievement to someone who values the collective journey and the relationships she has built.

Regarding key relationships, Nanami cares deeply for her fellow Wake Up, Girls! members. This is shown when she pleads with her parents to allow her to live in a shared dorm with the group instead of finishing school from home, demonstrating that the group and her friendships are worth sacrificing convenience for. Her interactions with the other members are marked by both her competitive nature and her underlying loyalty.

Notable abilities include her extensive training in singing, dancing, and playing the piano, which she has been practicing since childhood. These skills give her a strong technical edge as a performer within the group. Her pride and competitive spirit are also notable traits that drive her actions and contribute to her character arc.
