Description
Nanako Oohara is a twenty year old university student who first appears in the series after meeting Shinnosuke Nohara when he gets something in his eye while walking in the neighborhood. She stops to help him remove it, and from that moment Shinnosuke develops a deep affection for her, considering her his true love. She lives in the Lagarto apartment complex in Kasukabe.

Her personality is gentle, patient, and understanding. She is kind and easygoing, with a naive and sincere outlook that allows her to perceive and care for the emotions of others. Unlike most adults, she remains completely unruffled by Shinnosuke's unusual and mischievous behavior, which is a key part of her role in the story. She is the only person for whom Shinnosuke tries to behave properly, often becoming shy and blushing in her presence.

Her primary motivation is her aspiration to become a kindergarten teacher, a dream that aligns with her natural warmth and patience with children. She attends a women's university and is shown to be diligent in her studies. Beyond her personal goals, she acts as a kind older sister figure to Shinnosuke, inviting him on outings such as trips to the beach, skiing, and picnics, and often looks after him or spends time with his family.

Her role in the story is that of a recurring supporting character and the object of Shinnosuke's innocent romantic crush. She appears in many episodes and several films, often participating in adventures alongside the main cast. Her relationship with Shinnosuke is built on mutual fondness: she treats him with genuine care and amusement, while he consistently tries to impress her and protect her. She also interacts with other members of the Nohara family, including Shinnosuke's younger sister Himawari, and occasionally spends time with them at their home. She has a father who appears in some episodes, and there are storylines involving a potential fiancé and her part-time jobs.

Over the course of the series, Nanako shows little negative development, remaining a consistently kind and reliable presence. Her notable abilities include her emotional perceptiveness, her patience in dealing with Shinnosuke's antics without getting frustrated, and her practical caregiving skills, which are highlighted when she temporarily takes on a maternal role or helps care for a sick person. She is also physically active, participating in activities such as jogging and hiking, and is shown to be adaptable in various situations, from house sitting to handling unexpected events.
